Warning Signs Your Immobilizer Control Module Might Be Failing:
- Your car won't start, even though the battery is good and the starter is working.
- The security light on your dashboard stays on or flashes constantly.
- The car starts and then immediately stalls.
- You're having trouble with the key being recognized by the car.
- Intermittent starting problems that come and go.
How to Test if This Part is the Problem:
- Check the Basics: Make sure your car battery is fully charged and the starter is functioning correctly.
- Inspect the Wiring: Look for any damaged or corroded wires connected to the immobilizer control module.
- Try a Spare Key: If you have a spare key, try using it to start the car. If the spare key works, the problem might be with the original key.
- Professional Diagnosis: The best way to diagnose an immobilizer problem is to take your car to a qualified mechanic. They can use specialized tools to read the car's computer and pinpoint the exact cause of the problem.
Common Failure Causes:
- Electrical Surges: Power surges can damage the sensitive electronics inside the immobilizer control module.
