Pinpoint Test 6

PINPOINT TEST 6: THE HEADLAMPS ARE ON CONTINUOUSLY

Step 1 - 6:

Step 7 - 8:

Normal Operation
The SJB sends a reference signal to the multifunction switch through circuits (R/Y) (low beam request), (LG/B) (high beam request) and (DUO) (flash-to-pass request). When the SJB detects a request for the low beams, the SJB sends voltage through circuits (DG/O) (RH headlamp) and (DL/W) (LH headlamp) to the low beam headlamps. When the headlamps are on and the SJB detects a request for the high beams, the SJB sends voltage through circuits (DL/LG) (RH headlamp) and (W/LG) (LH headlamp) to the high beam headlamps.

When the SJB detects a request for the flash-to-pass, the SJB sends voltage through circuits (DL/LG) (RH headlamp) and (W/LG) (LH headlamp) to the high beam headlamps.

Possible Causes
- circuit (LG/B) short to ground
- circuit (DL/W) short to power
- circuit (DG/O) short to power
- circuit (DL/O) short to ground
- circuit (R/Y) short to ground
- circuit (W/LG) short to power
- circuit (DL/LG) short to power
- multifunction switch
