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

  Check the wire between fuse 11C/7 2 (5A) and central electronic module (CEM) connector 10C and 1C for a short circuit to ground as described in Short-circuit to ground, permanent faults .

  Do the necessary corrective action.

Are wires OK? 

• YES 

  Refer to Checking the wires 

• NO 

  OKAY:  Troubleshooting has been completed.

Check the wire between fuse 11C/7 2 (5A) and central electronic module (CEM) connector 10C and 1C for an intermittent short circuit to ground as described in Short-circuit to ground, permanent faults .

Replace fuse.

Do the necessary corrective action.
