Pinpoint Test 2

PINPOINT TEST 2: ONE OR MORE STOPLAMPS ARE INOPERATIVE

Step 1 - 5:

Step 6 - 8:

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. All the stoplamp are provided ground through circuit (B).

Possible Causes
- circuit (LB/B) open or short to ground
- circuit (B) open
- circuit (LG) open
- circuit (R/LG) open or short to ground
- high mounted stoplamp
- SJB
