Pinpoint Test 3

PINPOINT TEST 3: THE STOPLAMPS ARE ON CONTINUOUSLY

Step 1 - 7:

Step 8 - 10:

Normal Operation
When the brake pedal is applied, the stoplamp switch allows voltage to flow through circuit (LG). Circuit (LG) provides voltage to the high mounted stoplamp and the SJB. The SJB then provides power to the LH and RH rear lamps through circuits (LB/B) and (R/LG), respectively.

Possible Causes
- circuit (LB/B) short to power
- circuit (LG) short to power
- circuit (R/LG) short to power
- stoplamp switch
- cruise control module
- SJB
- PCM
- ABS module
