WARNING: This page is about a different variant/trim than selected.

Check wires to fog lamp for an open circuit Open-circuit, permanent faults , short circuit to ground Short-circuit to ground, permanent faults , and contact resistance and oxidation Contact resistance and oxidation .

Check relay (2/34).

HINT: The voltage across the relay should be 12 V at pins 1 and 3 when the fog lamp is on.
