Brake Lamp: Description and Operation

CIRCUIT OPERATION
Circuit F32 in the Power Distribution Center (PDC) feeds the stop lamp switch. A 20 Amp fuse in the PDC, cavity 16, protects circuit F32.

When the operator presses the brake pedal, the stop lamp switch CLOSES and connects circuit F32 to circuit L50. Circuit L50 connects to the right and left stop lamps. The L50 circuit is also spliced and supplies power for the Center High Mounted Stop Lamps (CHMSL).

Circuit Z1 provides ground for the stop lamps and CHMSL. The grounding point for the left and right stop lamps terminates at the rear body ground.

The grounding point for the CHMSL terminates at the liftgate ground.
