Test I: One Or More Stoplamps Are Inoperative

PINPOINT TEST I: ONE OR MORE STOPLAMPS ARE INOPERATIVE

Normal Operation
When the brake pedal is applied, the stoplamp switch closes and routes voltage to the high mounted stoplamp and the multifunction switch through circuit 10 (LG/RD). The multifunction switch then routes the voltage through circuits 9 (LG/OG) and 5 (OG/LB) to the LH and RH rear lamps, respectively. Ground for all the stoplamps is provided through circuit 57 (BK).

This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- High mounted stoplamp
- Multifunction switch
