Thank you for choosing Alcohol Interlock Systems, enclosed you will find a users manual that covers the day to day use of the ADS Determinator 2 interlock. After reading this entire manual, you should have a good understanding of the use of the device, if not re-read the material. Finally the installer will walk you through the basics. There is a lot of information here so take your time and familiarize yourself as much as you can with it.  We are here to help and have put together this information for you to succeed.  You may contact us via email:

 FACT:  Lease payments must be made on the install date of each month, unless you make other arrangements.  Alcohol Interlock Systems, LLC does not mail statements.  It is your responsibility to make your payments on time.   If for any reason you fall behind in your payments or can’t make payments, Coach Automotive Restylers, LLC will remove the device from your vehicle, report to Kansas Dept of Revenue, and will seek legal action for monies owed. It is your responsibility to notify Coach Automotive Restylers, LLC of any address, phone number or credit card change.  Operating hours are Monday – Friday, 9am to 5pm. Office phone is 913-677-9440. Fax phone is 913-677-9474.  Web site is

 FACT: You will receive 3 mouthpieces at the time of your install.  These mouthpieces are PLASTIC.  Be careful how you treat the hand held.  If you need more, MOUTHPIECES ARE $2 EACH

 FACT:  You will receive an appointment card for the next calibration date.  Each card will have a return date.  You are to present your hand held and your mileage on or before that date.  If you choose to present your handheld after that date, a penalty of $35 will apply. 

 FACT: Coach Automotive Restylers, LLC are closed for the major holidays:

Memorial Day; Independence Day; Labor Day; Thanksgiving Day & Black Friday; Christmas Day; New Year’s Day.  If the date of calibration is on a weekend or holiday, it must be calibrated the day before. 

 FACT:  Rental vehicles would not be available for use by the Lessee during the suspension and restriction period.

 FACT:  Some states such as Kansas will allow an IID to be installed on a motorcycle.  For safety reasons, Alcohol Interlock Systems, LLC will not install an IID on a motorcycle. 

 FACT: A driver on an interlock restriction may legally operate an employer’s vehicle without an ignition interlock installed during normal business activities provided you don't own or part own the vehicle or the business. This does not by pass the interlock requirement though - you will still have to have one in your own vehicle in order to complete the interlock requirement and get your regular license back. This provision does not apply to a driver who is on a limited ignition interlock - this is where you apply to KDOR to install the interlock early instead of being suspended.

 FACT:  The hand held has its own heater and will warm up after the unit is plugged in and the car turned to the “on” or “run” position.  Using any other method is unauthorized and may result in damage to the unit. If damage to the hand held occurs for any reason and is found to be a result of misuse then Lessee is responsible for the cost of repairs.

 FACT:  If the engine dies, or is turned off, a courtesy restart is allowed.  The vehicle may be restarted for up to two minutes.  Turn the key to the run position and wait for the device to say “you may start the vehicle”.  DO NOT ATTEMPT TO RESTART VEHICLE UNTIL YOU HEAR THE VOICE COMMAND. 

 DON’T:  DUE TO WEATHER OR THEFT, DO NOT LEAVE YOUR HAND HELD IN VEHICLE.  If damage to the hand held occurs for any reason and is found to be a result of misuse then Lessee is responsible for the cost of repairs.

 DO:  The interlock device has a blow/inhale/blow technique that needs to be learned.  Coach Automotive Restylers, LLC will provide a demonstration. Please listen carefully and follow directions.  Please read the device instructions thoroughly.  Instructions should be kept in vehicle to refer to them when needed. The IID will also instruct you to what you need to do to provide a successful sample.  If you have a problem and need to call the office for any reason, please be at your vehicle with the hand held.  You must provide us, word for word, the information given on the hand held.

 QUESTION:  Can an installation of an IID damage my vehicle?

ANSWER:  An IID is installed using wiring under the dashboard and in the engine compartment.  Once the device is removed, the vehicle will be restored to its condition prior to installation.

 QUESTION: Will the IID drain my vehicle’s battery?

ANSWER: The device draws less than .04 of an amp when not in use and less than half an amp when preparing for a test.  The device won’t drain the battery of a vehicle with a properly functioning electrical system unless the car has not started for 7 days.  A car with a compromised electrical system or weak battery may be affected sooner.

 QUESTION:  Will the IID lose its data if the vehicle’s battery is disconnected?

ANSWER:  The unit has a backup lithium battery that retains all data even if it loses its primary power.

 QUESTION: Will any disconnection of the vehicle’s power source be considered tampering with the IIID?

ANSWER: A driver OR a technician must contact the ignition interlock service provider before having any repairs done.  The repair shop must document any disconnection of the vehicle’s power source; otherwise it will be recorded as an attempt to tamper with the IID.  There is not a code that disables the IID.  You must stay with your car while the repairs are being made.  DO NOT allow technicians to provide a sample.

 DON’T: Any person tampering, circumventing, or otherwise misusing this device is subject to a fine, imprisonment, or both, and may be subject to civil liability.

 QUESTION: Will I be able to start my vehicle without a breath sample?

ANSWER: This can only be accomplished by a deliberate means of circumventing the ignition interlock. This would be considered tampering and would be recorded by the ignition interlock as a start violation.

 QUESTION: Can the IID be recalibrated/serviced at any time?

ANSWER:  The handheld will prompt the driver when to take the vehicle to the service center.  Call the service center in advance of your arrival.  The service center hours are Monday – Friday 9am to 5pm.  The service center closes promptly at 5pm. NO after -hour service.  If the IID is not recalibrated within the 30 days, it will allow a 7 day grace period.  On the 30th day, the device will say “LOCK DUE AT MIDNIGHT.  On the 31st day, the device will say “LOCK DUE IN 7 DAYS”.  If you choose to use any of the 7 days, there will be a $35 charge. This is considered by the State of Kansas being “NON-COMPLIANT” resulting in possible termination of driving privileges.

 QUESTION:  Are the IID units accurate?

ANSWER:  Every IID meets standards outlined by the National Highway Traffic Safety Administration (NHTSA).  When properly calibrated, the IID will accurately detect the presence of alcohol of any form. 

 QUESTION:  Will the IID shut the vehicle off?

ANSWER:  An IID CAN NOT shut off an engine once a vehicle is operating.

 QUESTION:  Can a vehicle, with an IID installed, be jump started off another car when vehicle’s battery is dead?

ANSWER:  When your car battery is dead, unplug the hand held unit from the cable.  You may jump-start your car from another car.  Turn off the other car. It CAN NOT be running or the key CAN NOT be on.  Leaving the other car on could cause the hand held to crash. 

 QUESTION: Can my friend/ family provide a sample?

ANSWER: The Lessee is informed that they are responsible for all samples recorded on the vehicle’s ignition interlock.

 QUESTION:  Can an IID spontaneously abort, preventing the vehicle from starting?

ANSWER:  The majority of aborts are caused by using an improper technique to blow into the collection tube i.e. “not in time”, “pressure too high” pressure too low”.  If you do not use the proper technique within 3 minutes the device will record a “NO RRT” violation. 

 QUESTION:  What happens when the hand held detaches from the cord while driving?

ANSWER:   The response from the hand held will be “unauthorized start, pull over” and it will beep continuously.  It will not record a violation. Simply pull over safely to re-attach the hand held.  Continue driving to your destination.

QUESTION:   Can a balloon or another source of air imitate human breath?

ANSWER:  The IID is equipped with an anti-circumnavigation device (thermometers) that detects air sources that do not come from a human.  The temperature from a human is approximately 98.7  If the hand held detects abnormal breath temperature, be sure to have a bottle of water in the vehicle.

 QUESTION:   Can I leave my vehicle running outside of a bar while drinking?

ANSWER:  Within minutes of driving away, the IID will require a random rolling sample.  If it detects alcohol present, it will record a violation.

 QUESTION:  Are random rolling tests dangerous while driving?

ANSWER:  Providing a sample while driving could be considered distracted driving. The driver has ample time to pull over.  The IID allows 3 minutes to perform a random rolling test.  If you do not use the proper technique within 3 minutes the device will record a ‘NO RRT” violation.  If you receive 5 or more violations in the 30 day period will result in notifying Kansas Dept of Revenue. When the 5th violation has occurred, a random amount of days will disappear causing an early recalibration.

 DON’T:  Having your car radio at its highest volume level could cause you not to hear the device ask for a sample.  If a sample is missed, a violation occurs.

 DON’T:  Leaving your vehicle unattended after starting could cause a missed random rolling test.  If a sample is missed, a violation occurs.

 QUESTION: Will a missed “RRT” cause the car’s engine to shut down while driving?

ANSWER:  The IID will require random rolling tests to ensure the driver remains alcohol-free.  A failure will not cause the engine to stop. It will merely record a violation. Missing a random rolling test is a violation as well as testing positive for alcohol.  If you receive 5 or more violations in a 30 day period will result in notifying Kansas Dept of Revenue, Div. of Vehicles.  When the 5th violation has occurred, a random amount of days will disappear causing an early recalibration.

 DO:  Recalibrate your hand held before the 30 days are over.  The device will notify you how many days are left and the day and date you are to return to the service center.  Be aware that if your device says Sat or Sun, be sure to get into the service center before the weekend or holiday.   Be sure to call your service center for appointment.

DON’T:  Waiting to get a recalibration after the 30 days plus the 7 day grace period will cause you to call service center for a lock-out code. Lock-out codes are good for 24 hours from the time the code is entered into the hand held.  Check with your service center for the additional cost of each code.

 DON’T:  If day 31 is used, the date on the hand held will change from the original service due date to a new service due date.  Using any of the 7 day grace period will result in a penalty fee.  Check with your service center for the cost.

 QUESTION: Can my engine stop following a failed a rolling test?

ANSWER: There is only one wire interrupted for the installation of the ignition interlock device and it serves no other purpose than to send the signal to the starter for the vehicle to start once the test is passed. If the individual fails a test while driving, it simply records a violation. IT DOES NOT SHUT YOUR VEHICLE OFF.

 QUESTION:  Is an alcohol breath sample of .08 within the alcohol limit programmed into the IID?

ANSWER:  The IID is programmed with a minimum alcohol limit of .03. If above this minimum, the IID will not allow the vehicle to start.  It will enter into a short lockout period of 14 minutes to allow any mouth alcohol to evaporate.  A second failed test will prompt the IID to go into a longer lockout period preventing the vehicle to start. 

 QUESTION:  Can I have one beer or glass of wine prior to attempting to drive?

ANSWER: If one drink is consumed one hour or more prior to startup, the average person will pass the test. Alcohol is normally metabolized at the rate of 1 ounce of alcohol per hour. It should be noted that size, gender, and several other factors play a key role in determining the body’s absorption of alcohol. There is no single formula that can be used for everybody in determining how much he or she can drink before they are affected by the alcohol.

 QUESTION:  Can anyone, other than the individual for whom the IID was ordered, use the vehicle?

ANSWER:   While it’s true that anyone can learn the breathing technique needed to use an IID, the unit requires random rolling retests to ensure the driver remains alcohol-free.  In addition, it’s a crime in most states to blow into an IID to start the vehicle for another person.  The individual for whom the IID was ordered is responsible for all failed tests.

 QUESTION:   Can aftershave, perfume, hairspray, cause an IID to fail?

ANSWER:  Even though these products contain alcohol and you don’t drink them, they will affect the operation of an IID.  Do not spray these products near the hand held or inside the cab of the vehicle.  If the hand held gets even a whiff of alcohol, it could test positive.

 QUESTION:  Will eating spicy foods cause the IID to fail?

ANSWER:  In some cases spicy foods, when mixed with the HCL in the stomach creates a gas called methane. With the non-alcohol specific devices the methane gas will create a false positive because the sensor reacts to the hydrocarbons. Anti-acids and water will usually relieve the situation. This phenomenon DOES NOT occur with the alcohol specific ignition interlock.

 QUESTION:  Will chocolate, mints, gum, doughnuts, pastries cause the IID to fail?

ANSWER:  Only alcohol-filled chocolate will affect the IID. The sugar and yeast in a pastry can prompt an IID to fail.  The sugar and yeast combined with the body’s natural acetone could test positive for alcohol.  Rinsing the mouth with water before using the unit is recommended to prevent failure.

 QUESTION: Can eating raw fruit and vegetables on the IID to fail?

ANSWER:  To prevent IID failure, do not consume any OLDER fruits or vegetables.  The major products of yeast fermentation are alcoholic drinks and bread.  Virtually any fruit, vegetable or sugary plant sap can be processed into an alcoholic beverage. The process is well known being essentially an alcoholic fermentation of sugars to yield alcohol and carbon dioxide.  Rinsing the mouth with water before using the unit is recommended to prevent failure.

 FACT:  Apple Cider Vinegar is used in salad dressings, marinades, vinaigrettes, food preservatives, and chutneys, among other things. It is made by crushing apples and squeezing out the liquid. Bacteria and Yeast are added to the liquid to start the alcoholic fermentation process, and the sugars are turned into alcohol. In a second fermentation process, the alcohol is converted into vinegar by acetic acid-forming bacteria (acetobacter). Acetic acid and malic acid give vinegar its sour taste.  Rinsing the mouth with water before using the unit is recommended to prevent failure.

 QUESTION:  Will cigarettes or chewing tobacco cause an IID to fail?

ANSWER:  Smokers are instructed to take several deep breaths before using an IID in order to maintain a steady blow.  While smoke does not affect the device, smoke should never be blown into an IID.  Tobacco should not be in the mouth during the collection process.  Any fluid getting into the device could cause the IID to short out.  If damage to the hand held occurs for any reason and is found to be a result of misuse then Lessee is responsible for the cost of repairs.  Smokers should keep a bottle of water in the vehicle in case of a breath temp error.

 QUESTION: Can eating strong foods help me beat a breath test?
ANSWER:  Eating can help you sober up over the long run, but it won't help you beat a breath test. People have tried eating foods like onions, coffee grounds, breath mints, but all to no avail. Strong substances such as these will often mask the odor of alcohol on your breath, but that doesn't make the alcohol content disappear. When you blow into a breathalyzer, the device will still be able to read the alcohol in your breath.

 QUESTION: Can drinking Zima register on a breathalyzer?
ANSWER: Because Zima does not smell as strongly of alcohol as other types of beer or liquor, there was a rumor floating around that drinking Zima, as your alcoholic beverage of choice would render your BAC undetectable by a breathalyzer. This myth, like that of eating breath mints or another strong substance, is based on the false assumption that there is no alcohol on your breath if there is no smell of alcohol. This is demonstrably false.

 FACT:  Kombucha is a centuries-old concoction that's made by mixing (or fermenting) black, green, or oolong tea and refined sugar with bacteria and yeast.  The amount of alcohol in the finished kombucha product should be minimal, less than 0.5%.  Keep in mind that some kombuchas are made to contain more alcohol.   U.S. Alcohol and Tobacco Tax and Trade Bureau (TTB) told several kombucha makers their fermented tea products contained too much alcohol.  The ignition interlock device starts testing for alcohol at .03%.  Rinsing the mouth with water before using the unit is recommended to prevent failure.

 QUESTION: Can gasoline fumes affect an IID?

ANSWER:  Normal refueling will not affect the operation of an IID.  If any gasoline is on hands or clothing and the hand held detects gas fumes, the IID could give a positive reading.

 QUESTION:  Can asthma inhalers cause the IID to test positive for alcohol?

ANSWER:  When using an inhaler, wait 15 to 30 mins before starting vehicle.

Asthma inhalers sometimes contain 30 percent or more alcohol that isn't absorbed into the bloodstream but is used as a propellant. Albuterol, the active ingredient in many asthma inhalers, also contains a methyl group and can trigger a false positive reading from a breath alcohol analyzer.

QUESTION: Can mouthwash/mouth spray give me a false positive ignition interlock result?

ANSWER:  Mouthwash and sprays usually contain up to 30% alcohol and will definitely react as alcohol in all ignition interlock devices. Non-alcohol mouthwash is available and all ignition interlock users should use this mouthwash. The alcohol concentration level can register as high as.250 but will immediately dissipate within a fifteen (15) minute timeframe due to being mouth alcohol only or quicker if the mouth is rinsed with water.

QUESTION:  Can dental adhesive or dental cleaner cause a positive reading for alcohol?

ANSWER: Dental adhesive and cleaner will not cause a positive reading for alcohol. When seeing a dentist for an exam, be sure to ask what products they use that contain alcohol.  Before leaving the dentist office, be sure to rinse your mouth thoroughly before blowing into the IID.

 QUESTION: Can pennies lower a person’s alcohol level?

ANSWER: Sucking on pennies or other copper has no effect on IID results. Even sillier is that people who believe it think the penny trick works because of the penny's high copper concentration. Pennies have been made of 97.5% zinc since the 1980s.

 FACT:  Some examples of familiar household uses of acetone (alcohol), as the active ingredient, are nail polish remover, paint thinner, varnish, printing inks, and resins.

FACT:  Hand sanitizers are commonly alcohol-based and may cause false-positive readings with a breathalyzer when the operator uses the hand sanitizer. The breathalyzer readings may be further elevated if more sanitizer is used or if it is not allowed to dry appropriately. No previous study has examined whether application of ethanol-based hand sanitizers by the person operating a common breathalyzer machine will affect the accuracy of the readings.

 FACT:  It is your responsibility that you do not consume alcohol in any form.  Be aware at all times that alcohol OR a form of alcohol could be in anything.  This is no longer about “drinking”.  The IID does not distinguish between different forms of alcohol.  Always check ingredient labels, restaurant menus, ask your doctor if alcohol is an ingredient in any medication you take.  Change to non-alcoholic mouth wash.  Keep these items away from the cab of your vehicle and your hand held. 

 FACT:  Diabetes is a very common disease in America.  If you're diabetic and have low blood sugar, you may have acetone in your blood.  IID does not actually measure the alcohol in the blood.  Rather, it uses infrared beams of light.  The light beams are absorbed by any chemical compound in the breath sample (including ethyl alcohol) that contains the “methyl group” in its molecular structure.  Thousands of compounds containing the methyl group can register as alcohol. One of these is acetone.  The machine is programmed to assume that the compound is “probably” alcohol.  It will read significant levels of alcohol on a diabetic’s breath, where in fact there may be little or none at all.  Monitoring your blood level is the key to a negative sample.

Displayed Message Explanation


Lockout: Enter Code (S/N 001001)

Unit is locked out either due to expiration of the service interval; notification of the pending lockout was displayed prior to the actual lock out. Provide the Hand Held’s Serial Number (it is displayed and printed on the unit’s rear label) to Alcohol Interlock Systems for a possible access code (fee will apply) A 5 digit code will be provided. Enter the code using the Hand Held’s keypad with the buttons representing the numbers 1, 2, and 3. The unit will allow for 24 hours of continued operation.


A random retest was not provided in the allotted time. Pull over as instructed and turn off the ignition.  Then retry.


No sample was provided in the allotted time. Pull over as instructed and turn off ignition. Then retry.


The temperature of the sample was too low or too high. Pull over as instructed and turn off ignition. Then retry.


A sample over the allowed limit was measured. If driving, pull over as instructed and turn off the ignition. Upon turning the ignition back to on you will see a NS X:XX this is a count down until you can retest (in Minutes) when this gets to 0:00 you can retest.  We highly recommend you rinse your mouth out with water and retest at least one time after a failed test. Before you do, consider what may have caused it and correct the situation, then retest.


System error: the internal ambient temperature is out of expected range. Turn off ignition roll windows down if hot and retry


System error: the heaters encountered an unexpected condition, this generally may be an indicator of a dead or low vehicle battery condition. Charge your vehicles’ battery up then retry. This error message will be gone when the vehicles’ battery has sufficient voltage to allow the device to heat up properly.


The Hand Held unit does not recognize the connected Vehicle Module. These two devices are paired at the Service Center and must remain matched.


The Hand Held could not communicate to the Vehicle Module. This could indicate a problem with either the device or the cable between them. Unplug the Hand Held check both sides of the connector for dirt or debris, blow out both with air, reconnect, and retry.


The Hand Held has an internal clock.  The clock has run out due to a glitch in the software.  The Hand Held will need to be brought back to the service center and exchanged for a new one.


                                                                                              Voice Prompts


The Determinator has several voice prompts that are spoken to alert the user to provide a sample or indicate the unit status.

 Spoken Prompt Explanation

 "Return for Service Soon"    Spoken after warm up if service is due in less than 5 days

 "Please Wait"    Spoken while heating, or before requesting a sample.

 "Determinator, Please Wait"    Start-up message

 "Please Provide Sample"    Spoken for a first test or rolling random retest. Provide a breath sample.

 "Please Retry Sample"    Previous sample failed. Provide another breath sample.

 "Provide sample now"    Spoken during a random retest if the first request is ignored

 "Provide Sample Now or Vehicle Lockout will begin"    Spoken during a random retest if the first two requests are ignored

 "Pull over and stop the vehicle"    The engine was detected as running without authorization to start/run. Continuing to drive after a positive alcohol sample or the failure to provide a random retest will also generate this message.

 "Invalid sample - Please wait"    Spoken if the provided sample could not be measured (temperature/pressure/etc.).

 "You May Start the Vehicle"     The vehicle may be started. Spoken if a proper sample was provided or if the engine dies and a courtesy restart is allowed.

 "Vehicle Starting is Disabled"     An alcohol positive sample was measured. The vehicle will not start.

 "Rolling Retest Passed. Thank You"    A valid sample was provided for a rolling random retest. A new random interval will be calculated.

 "Return for service now - Vehicle lockout"     Lockout period has elapsed. Vehicle is locked out and may not be started. If enabled, a code may be entered for a 24 hours grace period.
