Stoplamps and Center High Mount Stoplamp

Voltage is applied continuously from the stop fuse to the stoplamp switch. Voltage is applied from the stoplamp switch to junction block 1 C6 cavity 6 when the brake pedal is pressed. Voltage flows to junction block 1 CS cavity 7, continuing to SP450. At the same time that happens current flows through junction block 1 C3 cavity 1 to junction block 3 C3 cavity 2.

SP450 applies voltage to the following lamps:
^ The left and right stoplamps
^ The center high mounted stoplamp (CHMSL)

Junction block 3 C3 cavity 2 applies voltage to the following brake signal receivers:
^ Shift Lock Control Module (W/ automatic transaxle)
^ Brake Pressure Modulator Valve (W/ ABS)
^ Powertrain Control Module
