Replacing the component

The central electronic module (CEM) has registered an internal fault.

If the fault is intermittent, it has been registered previously but is no longer present. Intermittent faults can be caused by interference at start up of the central electronic module (CEM) or may be a different type of fault which occurs on different occasions. The fault is evaluated depending on how it occurs. Replace the central electronic module (CEM) if the fault recurs.

Replace the central electronic module (CEM) if the fault is permanent.

Remedy as necessary.
