Pinpoint Test 1

PINPOINT TEST 1: THE EXTERIOR LAMP(S) ARE INOPERATIVE

Step 1 - 6:

Normal Operation
The SJB sends a reference signal to the multifunction switch through circuit (W/B). When the SJB detects the multifunction switch in the parking lamps ON position, the SJB provides a ground for the parking lamp relay coil. Power to the parking lamp relay is provided internally by the SJB. When the parking lamp relay is energized, voltage is sent to the parking and license lamps.

Possible Causes
- circuit (W/B) open
- parking lamp relay
- multifunction switch
- SJB
