Test 60C - Parking Lamp Switch Output Circuit Short To Battery
NOTE:
Perform TEST 60A
before proceeding with this test. For connector terminal ID, see CONNECTOR IDENTIFICATION
. For wiring schematics, see WIRING DIAGRAMS
in this article. Perform TEST VER-1 - VERIFICATION PROCEDURE
after each repair.
- Disconnect headlight switch connector. If parking lamps turn off, replace parking lamp switch. If parking lamps do not turn off, go to next step.
- If vehicle is equipped with a parking lamp relay go to next step. Parking lamp relay is located behind dash, below parking lamp switch. If vehicle is not equipped with a parking lamp relay, repair short to battery voltage in Black/Yellow wire between BCM and headlight switch.
- Disconnect parking lamp relay. If parking lamps do not turn off, repair short to battery voltage in Black/Yellow wire between Body Control Module (BCM) and parking lamp relay. If parking lamps turn off, go to next step.
- Ensure ignition is off. Using an external ohmmeter, measure resistance between component terminals "B" and "D" on parking lamp relay. If resistance is less than 5 ohms, replace parking light relay. If resistance is 5 ohms or greater, go to next step.
- Disconnect BCM connectors. Using scan tool in ohmmeter mode, measure resistance at terminal "A" (Light Blue wire) on parking lamp relay socket. If resistance is less than 5 ohms, repair short to ground in Light Blue wire. If resistance is 5 ohms or greater, replace BCM.
