Pinpoint Test 3
PINPOINT TEST 3: THE PARKING, REAR OR LICENSE LAMPS ARE ON CONTINUOUSLYStep 1 - 7:
Normal Operation
The SJB sends a reference signal to the multifunction switch through circuit (W/B). When the multifunction switch is switched to the parking lamps ON position, the voltage signal is routed to ground through circuit (B/W). 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 through circuit (BR) to the parking and license lamps.
Possible Causes
- circuit (W/B) short to ground
- circuit (BR) short to power
- parking lamp relay
- multifunction switch
- SJB
