Damaged Microprocessor: One of the most common issues that can affect an ECM is a failure of the microprocessor. This can be caused by a variety of factors, including electrical surges, water damage, or physical impact. In many cases, a failed microprocessor can be replaced, allowing the ECM to be repaired and restored to its original functionality.
Circuit Board Damage: Another common issue that can affect the Cummins ISX ECM is corrosion or damage to the circuit board. This can be caused by exposure to moisture, heat, or other environmental factors. If the damage is not too severe, the circuit board can often be repaired by replacing damaged components or by rewiring damaged connections.
When you see these symptoms its a good idea to get a repair or replacement:
Engine misfires or runs roughly: If the engine is not firing properly, it may be due to a problem with the ECM.
Reduced fuel efficiency: A bad ECM may cause the engine to run less efficiently, resulting in decreased fuel economy.
Warning lights on the dashboard: If warning lights related to the engine come on, it may be a sign that the ECM is malfunctioning.
Engine stalling or not starting: A failed ECM may cause the engine to stall or prevent it from starting altogether.
