Replacing A Component

The Forward Sensing Module (FSM) has registered an internal fault in the forward facing radar.

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 Forward Sensing Module (FSM) 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 persists, replace the forward facing radar.

In the event of a permanent fault, replace the forward facing radar.

Remedy as necessary.
