Replacing The Component

The parking assistance module (PAM) 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 parking assistance module (PAM) or may be a different type of fault which occurs on different occasions. The fault is evaluated depending on how it occurs. Replace the parking assistance module (PAM) if the fault recurs.

Replace the parking assistance module (PAM) in the event of a permanent fault.

Remedy as necessary.
