Headlamp Alignment Switch: Testing and Inspection
HEADLAMP LEVELING SWITCH
WARNING: To avoid serious or fatal injury on vehicles equipped with airbags, disable the Supplemental Restraint System (SRS) 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 SRS. Failure to take the proper precautions could result in accidental
airbag deployment.
1. Disconnect and isolate the battery negative cable.
2. Disconnect the instrument panel wire harness connector from the upper instrument panel switch pod.
3. Using an ohmmeter, perform the resistance tests at the terminal pins in the switch pod connector receptacle as shown in the Headlamp Leveling
Switch Tests table.
4. If the switch fails any of the resistance tests, replace the ineffective upper switch pod as required. See: Sensors and Switches - Accessories and
Optional Equipment/Integrated Accessory Switch Assembly/Service and Repair/Instrument Panel Switch Pod - Removal.
