Pinpoint Test 3

PINPOINT TEST 3: THE HIGH BEAM HEADLAMPS ARE INOPERATIVE

Step 1 - 4:

Normal Operation
The SJB receives power from circuit (LG/Y). The SJB sends a reference signal to the multifunction switch through circuit (LG/B). When the multifunction switch is switched to the high beam position, the voltage signal is routed to ground through circuit (B/W). When the SJB detects the multifunction switch in the headlamps ON and in the high beam position, the SJB sends voltage to the high beam headlamps.

Possible Causes
- circuit (LG/B) open
- circuit (LG/Y) open
- multifunction switch
- SJB
