Brake Lamp: Description and Operation
During stop lamp operation, power is supplied from the STOP LP fuse in the underhood fuse block through CKT 1540 (ORN) to the TCC/stop lamp
switch. When the brake is depressed, the contacts of the TCC/stop lamp switch close, routing power to CKT 17 (WHT). CKT 17 supplies power to the
VECHMSL fuse and the high mount stop lamp relay coil. Current flows from the VECHMSL fuse through CKT 1320 (LT BLU) to the dome and high
mount stop lamp. The ground is provided by G202 through CKT 1850 (BLK). The high mount stop lamp relay coil is grounded through CKT 350
(BLK) to G102, which energizes the relay. When the high mount stop lamp relay is energized, current flows through CKT 895 (YEL) to the turn signal
switch. Current then flows to CKT 1418 (YEL/BLK) and CKT 1419 (DK GRN/WHT). CKT 1418 (YEL/BLK) supplies power to the LT TRN (rear)
fuse, which feeds the LH rear park and turn signal lamp terminal A, through CKT 618 (YEL). Ground is provided by CKT 1750 (BLK) to G475. CKT
1419 (GRN/WHT) supplies power to the RT TRN (rear) fuse, which feeds the RH rear park and turn signal lamp terminal A, through CKT 619 (DK
GRN). Ground is provided by CKT 2250 (BLK) to G422. When the left or right turn signal is turned ON, the appropriate turn signal will flash. The
opposite side will remain ON in order to serve as a stop lamp when the brakes are applied.
