• Ignition off.
• Remove connector from central electronic module (CEM).

  Check the wire between fuse 11C/32 2 (10A) and central electronic module (CEM) connector 6E for a short circuit to ground as described in Short-circuit to ground, permanent faults .

  Do the necessary corrective action.

  Additional information:
