Daytime Running Lamp Relay: Service and Repair
DAYTIME RUNNING LAMP RELAYWARNING: TO AVOID PERSONAL INJURY OR DEATH, ON VEHICLES EQUIPPED WITH AIRBAGS, DISABLE THE SUPPLEMENTAL RESTRAINT SYSTEM BEFORE ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, AIRBAG, OCCUPANT CLASSIFICATION SYSTEM, 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.
NOTE: The DRL relay is installed in the Junction Block (JB) on the driver side outboard end of the instrument panel. Vehicles equipped with this relay MUST NOT have a headlamp high beam relay installed in the JB. Also, although the terminals of the DRL relay are laid out in a footprint that is similar to that of a conventional International Standards Organization (ISO) relay, a standard ISO relay MUST NEVER be installed in the place of the DRL relay.
REMOVAL
1. Disconnect and isolate the battery negative cable.
2. Remove the trim from the driver side end of the instrument panel.
3. Remove the Daytime Running Lamp (DRL) relay (3) by grasping it firmly and pulling it straight out from the receptacle in the JB.
INSTALLATION
1. Position the Daytime Running Lamp (DRL) relay to the proper receptacle (3) in the JB. The adjacent receptacle (2) must NOT be populated by a headlamp high beam relay on a vehicle that is equipped with a DRL relay.
2. Align the DRL relay terminals with the cavities in the JB receptacle.
3. Push firmly and evenly on the top of the DRL relay until the relay base is fully seated in the JB receptacle.
4. Reinstall the trim onto the driver side outboard end of the instrument panel.
5. Reconnect the battery negative cable.
