Video Summary
Sure, here's a summary of the video.- An ignition control module (ICM) controls the timing of spark plugs.
- The ICM is connected to the distributor cap and rotor assembly.
- A bad ICM can cause a bad smell, engine overheating, no power, poor performance, and/or stalling.
- To check the ICM, one must measure voltage across the igniter coil with a multimeter.
- The ignition switch and/or coils should be replaced if the voltage reading is less than 12 volts.
- The distributor or distributor gears are broken if the rotor cannot turn.
- The ICM may last between 5-10 years if well maintained.
