Replacing The Component

The engine control module (ECM) has registered an internal fault.

If the fault is intermittent, it has been registered previously but no longer remains. Intermittent faults can be due to disruption when the engine control module (ECM) started or can be another type of fault that may recur at different instances. The fault is assessed on a case by case basis. If the fault recurs, replace the engine control module (ECM).

In the event of a permanent fault, replace the engine control module (ECM).

Remedy as necessary.
