3360228 - I05 DIPPED HEADLAMPS NOT WORKING

Neither of the dipped beams work under any circumstances (either in manual or AUTO mode). When the appropriate lever on the stalk unit is raised or lowered with the key ON, or the appropriate button is pressed, the turn signals/hazard lights work but the intermittent operation is irregular.

Dipped beams are controlled by the Body Computer Node via a relay on the Facia Control Unit.

Lights can be turned on/off by means of the following controls:

• Specific control (Exterior lighting control)
• Control from dusk sensor
• Follow me home control
• Dipped beam maintenance control when main beams on
