Replace Front Roof Console

Information 

The > 9900 - PIWIS Tester 3  instructions take precedence and may be different.

Information 

If the fault memories of individual control units (e.g. fault memories of the control units for front-end electronics, rear-end electronics, etc.) cannot be erased, proceed as follows:

• Switch off ignition.
• Disconnect the PIWIS Tester from the vehicle.
• Lock the vehicle using the driver's key.
• Wait approx. 1 minute before unlocking the vehicle again.
• Connect the PIWIS Tester to the vehicle.

If control units are found to have faults, which cannot be erased and are not caused by replacing the front roof trim panel, these faults must be found and corrected.
