Headlamp Relay: Testing and Inspection
The headlamp (or security) and horn relays are located in the Power
Distribution Center (PDC) in the engine compartment. Each of these relays can be tested as described in the following procedure, however the circuits
they are used in do vary To test the relay circuits.
WARNING: ON VEHICLES EQUIPPED WITH AIRBAGS, REFER TO AIRBAG AND SEAT BELTS/AIR BAGS BEFORE ATTEMPTING
ANY STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE. FAILURE TO
TAKE THE PROPER PRECAUTIONS COULD RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL
INJURY.
Relay Terminals
Remove the relay from the PDC to perform the following tests:
1. A relay in the de-energized position should have continuity between terminals 87A and 30, and no continuity between terminals 87 and 30. If OK,
go to Step 2. If not OK, replace the faulty relay.
2. Resistance between terminals 85 and 86 (electromagnet) should be 75 ± 5 ohms. If OK, go to Step 3. If not OK, replace the faulty relay
3. Connect a battery to terminals 85 and 86. There should now be continuity between terminals 30 and 87, and no continuity between terminals 87A
and 30. If OK, test the relay circuits. If not OK, replace the faulty relay
