Replacing The Component

If the other control modules on the MOST network are working normally, there is probably an internal fault in the phone module (PHM).

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 phone module (PHM) or may be a different type of fault which occurs on different occasions. The fault is evaluated depending on how it occurs. If the fault recurs, replace the control module.

In the event of a permanent fault, replace the control module.

Remedy as necessary.
