Normal Operation
When the brake pedal is applied, voltage is routed to the high mounted stoplamp through circuit 15S-LG6 (GN/YE) and the generic electronic module (GEM) through circuit 15S-AA72 (GN/YE). Ground for the high mounted stoplamp is provided through circuit 31-LG6 (BK). The GEM provides voltage to the LH and RH rear lamps through circuits 49S-LG12 (BU) and 49S-LG19 (BU/RD), respectively. Ground is provided to the LH and RH rear lamps through circuits 31-LF23 (BK) and 31-LF24 (BK), respectively.
