Replacing A Component

The control module 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 problem returns, load the Forward Sensing Module (FSM) with new software.

If downloading of new software did not help, replace the Forward Sensing Module (FSM).

Remedy as necessary.
