What Are The Symptoms Of A Bad Ignition Control Module In Mercedes-Benz?

Ignition control module can control the frequency and amount of spark getting to the engine.

In a Mercedes-Benz, it is responsible for turning the ignition system on and off.

Within the ignition control module (ICM), a small sensor is responsible for: Firing the ignition coil Energy to trigger the spark plugs Ignite the air-fuel mixture

Over time of use, the ignition control module can go bad due to plenty of reasons.

If the ICM starts to fail, your Mercedes-Benz will show the following symptoms.

ENGINE STALLING

Bad ICM doesn't provide the right spark, so the car is unable to burn the air-fuel mixture and is left with some unburnt fuel.

As a result, the air-fuel mixture can get disturbed and cause engine stalling.

ILLUMINATED CHECK ENGINE LIGHT

Like other signs, the bad ICM also triggers the check engine light on the dashboard.

Take your car to the nearest repair shop for determining the causes behind it.

DIFFICULT STARTING

Combustion process will require 4 main inputs to start and drive properly: Exhaust Compression Spark Fuel

When the ignition control module fails, your car doesn't start or has difficulty starting.

ENGINE RUNNING ROUGH

ICM controls the frequency of ignition spark and is directly linked to the combustion process.

As a result, it will cause incomplete combustion and lead to a rough engine running.

CONCLUSION

Ignition control module is the sensitive component in your engine block.

If it is failed in your Mercedes-Benz, then consult a mechanic to fix it ASAP.
