Replacing A Component

The Forward Sensing Module (FSM) 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 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 recurs, try downloading new software to the control module. If this does not help, replace the Forward Sensing Module (FSM).

In the event of a permanent fault, try downloading new software to the control module. If this does not help, replace the Forward Sensing Module (FSM).

Remedy as necessary.
