Test H: One Or More Stoplamps Are Inoperative

PINPOINT TEST H: ONE OR MORE STOPLAMPS ARE INOPERATIVE

Normal Operation
Voltage is supplied from the bussed electrical center (BEC) to the smart junction box (SJB) through circuits 1523 (DG), 905 (GY/LB), and 1052 (TN/BK) to power the LH stoplamps, RH stoplamps, and the high mounted stoplamp.

The stoplamp switch is provided voltage through circuit 10 (LG/RD). When the brake pedal is applied, the stoplamp switch routes voltage to the SJB through circuit 511 (LG). The SJB then provides voltage to the stoplamps through circuits 1783 (RD/WH), 1374 (TN/LB), 1728 (LB/OG), and 1363 (WH/RD). Ground for the stoplamps is provided through circuit 1205 (BK).
