Breathalyzer Causing Car Problems: Fact or Fiction?

A breathalyzer, or ignition interlock device (IID), installed in your car can sometimes seem like the source of various vehicle issues. Are these problems directly caused by the breathalyzer, or is there something else going on? This article delves into the potential car problems associated with breathalyzers, helping car owners, mechanics, and technicians understand, diagnose, and resolve these issues.

Understanding the Breathalyzer’s Impact on Your Car

Breathalyzers, primarily designed to prevent drunk driving, are electronic devices connected to your car’s ignition system. They require a breath sample before the engine can start. While they serve a crucial safety purpose, their installation and operation can sometimes lead to unintended consequences for your vehicle. These problems can range from minor inconveniences like slow starts to more significant issues involving the electrical system.

Common Car Problems Potentially Linked to Breathalyzers

  • Dead Battery: A constant drain on the battery, especially in older vehicles, can be a side effect of a poorly installed or malfunctioning breathalyzer.
  • Starting Issues: Difficulty starting the car, even after passing the breath test, can be attributed to wiring problems or a failing breathalyzer unit.
  • Electrical Malfunctions: Breathalyzers are integrated into the car’s electrical system, and a faulty installation can interfere with other electrical components.
  • Diagnostic Trouble Codes (DTCs): The presence of a breathalyzer can sometimes trigger DTCs, making it challenging to pinpoint the actual problem.

Troubleshooting Breathalyzer-Related Car Issues

When facing car trouble with an installed breathalyzer, it’s essential to approach the problem systematically. Here’s a step-by-step guide to help you troubleshoot:

  1. Check the Breathalyzer Unit: Ensure the unit is functioning correctly. Try a test blow and observe for any error messages.
  2. Inspect the Wiring: Examine the wiring connections for any loose or damaged wires. A poorly connected wire can disrupt the car’s electrical system.
  3. Test the Battery: A weak or dying battery can exacerbate breathalyzer-related issues. Have the battery tested and replaced if necessary.
  4. Consult the Manual: Refer to the breathalyzer’s manual for troubleshooting tips specific to the device.
  5. Seek Professional Help: If you’re unable to identify the problem, consult a qualified auto technician or the breathalyzer installer.

Diagnosing Electrical System Interference

Electrical issues caused by a breathalyzer can be particularly tricky to diagnose. Using a diagnostic scanner can help identify any DTCs related to the ignition or electrical systems.

“A common mistake people make is assuming the breathalyzer is always the culprit. A thorough diagnostic check is essential to pinpoint the real issue.” – John Smith, Automotive Electrical Engineer.

Breathalyzer Maintenance and Prevention

Regular maintenance can help prevent many breathalyzer-related car problems. This includes:

  • Calibration: Ensure the breathalyzer is calibrated regularly as per the manufacturer’s recommendations.
  • Cleaning: Keep the mouthpiece and unit clean to ensure accurate readings and prevent malfunctions.
  • Visual Inspection: Periodically check the wiring and connections for signs of wear and tear.

“Regular maintenance not only keeps the breathalyzer functioning accurately but can also prevent potential car problems down the road.” – Jane Doe, Certified Breathalyzer Technician.

Conclusion: Addressing Breathalyzer Car Problems Effectively

While breathalyzers can occasionally contribute to car problems, they are essential safety devices. Understanding the potential issues and following the troubleshooting steps outlined above can help you address these problems effectively. Regular maintenance and professional installation are key to preventing issues and ensuring the smooth operation of both your vehicle and the breathalyzer. Need help?
