Brake Lamp: Description and Operation
STOP LAMPS
The STOP LP SW fuse in the underhood fuse block supplies battery positive voltage to the normally open stop lamp switch. When the driver presses the
brake pedal, the switch contacts close. The battery positive voltage flows to the left stop lamp assemblies, to the right stop lamp assemblies, and to the
center high mounted stop lamp (CHMSL). The left stop lamp and the CHMSL have ground at G402. The right stop lamp has ground at G401.
