If the fault is intermittent, it has been registered previously but is no longer present. Intermittent faults can occur at start up of the phone module (PHM), or may be a different type of fault that occurs on different occasions. The fault is evaluated depending on how it occurs.

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