Test K: All The Stoplamps Are Inoperative

PINPOINT TEST K: ALL THE STOPLAMPS ARE INOPERATIVE

Normal Operation
The stoplamp switch is supplied voltage through circuit 10 (LG/RD). When the brake pedal is applied, the stoplamp switch routes voltage to circuit 511 (LG). Circuit 511 (LG) supplies voltage to the multifunction switch and the high mounted stoplamp. The multifunction switch internally routes the voltage (when in the NEUTRAL position) to circuits 9 (LG/OG) (LH stoplamp) and 5 (OG/LB) (RH stoplamp). Circuits 9 (LG/OG) and 5 (OG/LB) are routed through the central junction box (CJB) to the LH and RH stoplamps, accordingly.

This pinpoint test is intended to diagnose the following:
- Fuse
- Wiring, terminals or connectors
- Stoplamp switch
- CJB
