Fault-Tracing Information

The control module has previously registered a fault but the fault is no longer active.

Intermittent faults may be due to interference at start up of the control module 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, replace the control module. Remedy as necessary.

In the event of a permanent problem, replace Start control module (SCU).
