Replacing The Control Modules And Downloading Software

Suspension module (SUM) has detected an internal fault. If the fault is intermittent, the fault has been detected on a previous occasion. In the event of intermittent faults, no corrective action need be carried out if the fault does not recur. The fault is evaluated depending on how it occurs.

In the event of a permanent internal fault, the control module must be replaced.

After replacing control module, new software shall be downloaded and the control module shall be calibrated.

Remedy as necessary.
