Replacing A Component

The phone module (PHM) has registered a fault on the integrated GSM/GPRS unit.

If the fault is intermittent, it has been registered previously but is no longer present. Intermittent faults may be due to interference upon start-up or may be another type of fault that can recur at different times. The fault is evaluated depending on how it occurs. f the fault recurs, replace the phone module (PHM).

In the event of a permanent fault, replace the phone module (PHM).

Remedy as necessary.
