REAR FOG LAMPS NOT WORKING

When the rear fog lamp switch is operated with the dipped beam headlamps on (or front fog lamps on), the rear fog lamp does not work, and this fault is indicated by the relevant warning light.

If the rear fog lamp does not work and the Instrument panel Node does not signal this, also see Table I30 LIGHTS NOT WORKING CHECK. If the dipped beam headlamps do not work either, first see Table I05
