Headlamp: Testing and Inspection

FAULT DIAGNOSIS HINTS
The headlamp is activated when ignition switch 20 is in the Drive position and when light switch 10 is in position 2.
1. Check that fuses 7 and 8 (full beam), and 5 and 6 (dipped beam) are intact and supplied with current.
2. Check that the lamps are intact and supplied with current.
3. Check the grounding of each lamp.
4. Check the light switch, the lighting relay, the dip- switch connections and filament monitor connections.
5. Check the operation of relay 78 and resistor 80 by taking readings on the connections.
6. Check the connectors, wiring harness and ground connections.

For fault diagnosis on the Parking Lights, see the Parking Lights.

IMPORTANT: When changing the bulbs, make sure that the new bulbs are of the correct rating. Otherwise, the lamps in the pictogram may light up due to imbalance in the filament monitor coil.
