Test 55D - Repairing Parking Lamps Inoperative In Auto Mode
NOTE:
For connector terminal identification, see CONNECTOR IDENTIFICATION
. For wiring diagrams, see WIRING DIAGRAMS
. Perform TEST VER-1 after each repair.
CAUTION:
Always turn ignition switch to OFF position prior to disconnecting any module connector.
- Using DRB, actuate parking lamp relay. If parking lamps toggle on and off, replace Body Control Module (BCM). BCM is located behind right kick panel. If parking lamps do not toggle on and off, go to next step.
- Turn ignition switch to OFF position. Disconnect BCM Gray connector. Connect jumper wire between BCM Gray connector terminal No. 24 (Light Blue wire) and ground. If parking lamps illuminate, replace BCM. If parking lamps do not illuminate, go to next step.
- Disconnect jumper wire. Remove parking lamp relay. Parking lamp relay is located behind dash, below parking lamp switch. Using DRB in voltmeter mode, check voltage on parking lamp relay connector terminal "B" (Pink/Red wire). If voltage is less than 10 volts, repair open Pink/Red wire. If voltage is more than 10 volts, go to next step.
- Using DRB in voltmeter mode, check voltage on parking lamp relay connector terminal "C" (Pink/Red wire). If voltage is less than 10 volts, repair open Pink/Red wire. If voltage is more than 10 volts, go to next step.
- Connect jumper wire between parking lamp relay connector terminals "B" (Pink/Red wire) and "D" (Black/Yellow wire). If parking lamps do not illuminate, repair open Black/Yellow wire. If parking lamps illuminate, go to next step.
- Disconnect jumper wire. Using an external ohmmeter, check resistance of Light Blue wire between BCM Gray connector terminal No. 24 and parking lamp relay terminal "A". If resistance is more than 5 ohms, repair open Light Blue wire. If resistance is less than 5 ohms, replace parking lamp relay.
