Brake Light Switch: Testing and Inspection
BRAKE LAMP SWITCH
WARNING: To avoid serious or fatal injury on vehicles equipped with airbags, disable the supplemental restraint system before attempting
any steering wheel, steering column, airbag, seat belt tensioner, impact sensor, or instrument panel component diagnosis or service. Disconnect
and isolate the battery negative (ground) cable, then wait two minutes for the system capacitor to discharge before performing further
diagnosis or service. This is the only sure way to disable the supplemental restraint system. Failure to take the proper precautions could result
in accidental airbag deployment.
1. Disconnect and isolate the battery negative cable.
2. Disconnect the wire harness connector from the brake lamp switch.
3. Using an ohmmeter, perform the continuity tests at the terminal pins in the brake lamp switch connector receptacle as shown in the Brake Lamp
Switch Tests table.
4. If the switch fails any of the continuity tests, replace the ineffective brake lamp switch as required.
