Exterior Light Test 5A - Parking Lights Will Not Turn Off
NOTE:
Perform EXTERIOR LIGHT TEST 1A
before proceeding with this test. For connector terminal ID, see CONNECTOR IDENTIFICATION
and WIRING DIAGRAMS
. Perform TEST VER-1A - VERIFICATION PROCEDURE
after each repair.
CAUTION:
Always turn ignition switch to OFF position prior to disconnecting or connecting any module connector.
- Using scan tool, read park lamp switch sense. If scan tool displays PARK LAMP SW: CLOSED, go to next step. If scan tool does not display PARK LAMP SW: CLOSED, go to step 4).
- Disconnect headlight switch. If scan tool displays PARK LAMP SW: CLOSED, go to next step. If scan tool does not display PARK LAMP SW: CLOSED, replace headlight switch.
- Disconnect junction block connector "A". See Figure in CHIME TEST 2A. Using scan tool in ohmmeter mode, measure resistance on headlight switch connector terminal No. 8 (Light Green/Red wire). If resistance is less than 5 ohms, repair Light Green/Red wire for short to ground. If resistance is 5 ohms or greater, replace Body Control Module (BCM). BCM is located with junction block under driver's side instrument panel. See Figure in CHIME TEST 2A.
- Disconnect park lamp relay. See Figure in EXTERIOR LIGHT TEST 2A. If parking lights turn off, go to next step. If parking lights do not turn off, repair park lamp relay output circuit for short to voltage.
- Using external ohmmeter, measure resistance between ground and terminal "C" on park lamp relay socket. If resistance is 100 ohms or greater, replace park lamp relay. If resistance is less than 100 ohms, repair park lamp relay control circuit for short to ground.
