Checking Brake Switch

NOTE: For circuit identification and wiring diagram, see WIRING DIAGRAMS article. After each repair procedure has been completed, reconnect all components. Perform TEST VER-2  under VERIFICATION TESTS to ensure system is functioning properly. Brake switch is also referred to as brakelight switch.

Turn ignition on, with engine off. Using scan tool, read brake switch input while pressing and releasing brake pedal. If scan tool reading corresponds to position of brake pedal, brake switch is functioning properly. Test is complete. If scan tool reading does not correspond to position of brake pedal, replace brake switch.
