- Perform TEST VER-1 after each repair.
- Disconnect headlamp 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 headlamp 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, check resistance between parking lamp relay terminals "B" (Pink/Red wire) and "D" (Black/Yellow wire). If resistance is less than 5 ohms, replace parking light relay. If resistance is more than 5 ohms, go to next step.
- Disconnect BCM connectors. Using scan tool in ohmmeter mode, check resistance of parking lamp relay connector terminal "A" (Light Blue wire). If resistance is less than 5 ohms, repair short to ground in Light Blue wire. If resistance is more than 5 ohms, replace BCM.
