How to Fix the Ignition Control Module on an Audi 80?

The ignition control module (ICM) is a crucial component in the Audi 80's ignition system. When it fails, the car may not start or experience intermittent stalling. How can I diagnose and fix this issue?

First, use an ohmmeter to check the resistance of the ICM's terminals. A reading of 0 or infinite resistance indicates a faulty module. Replace it with a new one from a reputable brand.

If the ICM is getting power but still not working, check for any loose or corroded connections. Clean or tighten them as needed. Additionally, make sure the ground straps are in good condition and properly connected.
