Troubleshooting Ignition Interlock Malfunctions
Draeger Interlock devices help protect drivers by preventing alcohol impaired driving and are easy to use. If issues with the device’s usage do arise, our ignition interlock devices display easy-to-read messages to help you provide a correct breath sample so that you can get back on the road quickly. If you are experiencing ignition interlock device problems, the easiest way to resolve malfunctions is understanding how to use your device properly and what to do in case you experience any device issues.

However, if your device does show an error, don’t worry. Error messages on Draeger Interlock devices are self-explanatory and simple to troubleshoot.
Breath Test Messages
If you’re experiencing issues passing the breath test on your interlock device, or you see a flashing red light or hear a beep, check the display. It should provide a simple and clear message to help you troubleshoot. Here are some of the most common ignition interlock device problems:
Blow Longer! Repeat Test
This error means your breath sample didn’t last long enough. Press the OK button and wait a moment while the interlock resets. After a brief wait, blow slowly into the mouthpiece until you hear the tone stop, ensuring the blow lasts long enough for the device to obtain a complete sample.
Blow Stronger! Repeat Test:
Similar to the previous error, this means the breath sample you provided didn’t have enough force. Press the OK button and wait again, then blow into the mouthpiece with more force. Continue until the tone stops, blowing enough for the system to read the sample.
Suck After Blow Repeat Test:
For the ignition interlock to successfully analyze your sample and clear you to drive, it needs to test the sample in both directions. Retake the test and wait for the tone to stop, do not remove your mouth from the mouthpiece, and then sharply suck air back in through the device. Continue until you hear a beep.
This ignition interlock malfunction occurs when the IID detects low air quality, and it’s unable to analyze the sample successfully. The easiest way to resolve this error is to rinse your mouth with water and open the windows of the vehicle to ensure the air it’s detecting is clean. While you’re doing this, press OK on the IID, and it will begin a countdown. After the countdown finishes, test again.
Due to state requirements, the ignition interlock is set to request a retest at random intervals following your initial test. The device will beep with a continuous tone. Press the OK button and test again. If the test fails, your vehicle may begin honking and flashing lights, if required by your jurisdiction. You can disable this by turning the car off. If the device has an active countdown, you’ll need to wait for it to finish to test again. Remember, Draeger strongly recommends that you pull over to a safe location to perform any retests.
The ignition interlock device must be serviced within specified periods on an ongoing basis (typically every 30 to 60 days, depending on your state’s requirements). If the device is not taken to a service location within the required period, it will lock you out and display “Service Lockout.” The device will display a several day service countdown before you are locked out. When this happens, call your technician or service center for assistance. A lockout can be frustrating, and it’s critical to ensure you handle it according to your state requirements.
