Pinpoint Test 1

PINPOINT TEST 1: THE STOPLAMPS ARE INOPERATIVE

Step 1 - 4:

Normal Operation
The stoplamp switch is supplied battery voltage through circuit (LG/R) from the SJB. When the brake pedal is applied, the stoplamp switch allows voltage to flow through circuit (LG). Circuit (LG) sends voltage to the high mounted stoplamp and SJB, which in turn provides power to the LH and RH rear lamps.

Possible Causes
- circuit (LG/R) open
- circuit (LG) open
- stoplamp switch
- SJB
