Test point 21: Elimination:

• Replace support with gear unit.
• Actuate switch for memory seat adjustment.

The text in the fault memory changes from present  to not present  if the cause of the fault has really been eliminated.

If the fault is still present,  there is a fault in the wire.

For a fault in the wire, proceed as described below:

• Disconnect plug at support with gear unit. 
• Disconnect mirror  plug from the control module.
• Use an ohmmeter to check for short circuit on the support  plug Pin 1, wire color grey, and Pin 7, wire color pink. No continuity must be measured! If no short circuit is detected:
• Use an ohmmeter to check for open circuit on the support plug  Pin 3 and the mirror plug  on the control module Pin 5 Ohmmeter display <5ohm
• Use an ohmmeter to check for continuity on the support plug  Pin 1 and Pin 7.
• If no fault is detected in the wire but the fault is still present,  replace the control module.
