Pinpoint Test 2
PINPOINT TEST 2: THE FOG LAMPS ARE ON CONTINUOUSLYStep 1 - 3:
Step 4:
Normal Operation
The SJB sends a reference signal to the fog lamp switch through circuit (DL/W). When the fog lamp switch is engaged, the voltage signal is routed to ground through circuit (B/W).
When the SJB detects the fog lamp switch has been pressed, the SJB provides a ground for the fog lamp relay coil through circuit (LB/B). When the fog lamp relay is energized, voltage is sent through circuit (T/O) to the fog lamps.
Possible Causes
- circuit (LB/B) short to ground
- circuit (T/O) short to power
- fog lamp relay
- SJB
