Checking fuses and wires

Check that the fuses 11C/30 (group 1) and 11C/31 (group 2) respectively in the interior are intact.

For group 1, check the wires between:

• fuse 11C/30 and shunt 20/28
• shunt 20/28 and left or right lower lamp body 1 (in boot)

for an open circuit as described in Open-circuit, permanent faults , and for a short circuit to ground as described in Short-circuit to ground, permanent faults .

For group 2, check the wires between:

• fuse 11C/31 and shunt 20/33
• shunt 20/33 and left or right lower lamp body 2 (in boot)

for an open circuit as described in Open-circuit, permanent faults , and for a short circuit to ground as described in Short-circuit to ground, permanent faults .

Regardless of the group, also check the ground wires between the left or right lower lamp housing 4 (in the boot) and the ground point for an open circuit as described in Open-circuit, permanent faults .

Check the control unit connector B1 and lock unit connector 6 for Contact resistance and oxidation and check the intermediate wire for an open circuit as described in Open-circuit, permanent faults .

Do the necessary corrective action.
