Test 50A - Parking Lamps Inoperative In Auto Mode
NOTE:
Perform TEST 47A
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.
CAUTION:
Always turn ignition off prior to disconnecting any module connector.
- Using scan tool, 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 off. Disconnect BCM Gray connector. Connect jumper wire between ground and terminal No. 24 (Light Blue wire) on BCM Gray connector. 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 scan tool in voltmeter mode, measure voltage at terminal "B" (Pink/Red wire) on parking lamp relay socket. If voltage is 10 volts or less, repair open Pink/Red wire. If voltage is more than 10 volts, go to next step.
- Using scan tool in voltmeter mode, measure voltage at terminal "C" (Pink/Red wire) on parking lamp relay socket. If voltage is 10 volts or less, repair open Pink/Red wire. If voltage is more than 10 volts, go to next step.
- Connect jumper wire between terminals "B" (Pink/Red wire) and "D" (Black/Yellow wire) on parking lamp relay socket. 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, measure resistance between terminal No. 24 (Light Blue wire) on BCM Gray connector and terminal "A" on parking lamp relay socket. If resistance is 5 ohms or greater, repair open Light Blue wire. If resistance is less than 5 ohms, replace parking lamp relay.
