Test 4 - Parking Lamp Switch Power Supply
NOTE:
For connector terminal identification and wiring diagrams, see BODY CONTROL COMPUTER
section in this article. Perform TEST VER-1
VERIFICATION TEST after each repair.
NOTE:
Low battery or momentary Chrysler Collision Detection (CCD) bus failure may cause DTCs to set.
- Remove and inspect fuse No. 9. See Figure . If fuse is open, go to TEST 64A . If fuse is okay, use scan tool in voltmeter mode to check voltage on fuse No. 9 (Pink/White wire). If voltage is more than 10 volts, go to step 4). If voltage is 10 volts or less, go to next step.
- Gain access to Power Distribution Center (PDC). PDC is located in engine compartment in front of left strut tower. Remove and inspect fuse "I". See Fig 1 . If fuse is open, repair short to ground in Pink/White wire and replace fuse. If fuse is okay, go to next step.
- Using scan tool in voltmeter mode, check voltage on fuse "I" connector (Black wire). If voltage is 10 volts or less, repair or replace PDC as necessary. If voltage is more than 10 volts, repair open Black wire.
- Reinstall fuse. Disconnect headlight switch. Using scan tool in voltmeter mode, check voltage on headlight switch 7-pin connector terminal No. 4 (Pink/Red wire). 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 headlight switch 7-pin connector terminals No. 4 (Pink/Red wire) and No. 5 (Black/Yellow wire). If parking lamps illuminate, replace headlight switch. If parking lamps do not illuminate, go to next step.
- Turn ignition off. Disconnect Body Control Module (BCM) connector. BCM is located behind right kick panel. Using scan tool in voltmeter mode, check voltage on BCM Bone connector terminal No. 23 (Black/Yellow wire). If voltage is 10 volts or less, repair open Black/Yellow wire between headlight switch and BCM. If voltage is more than 10 volts, repair open Black/Yellow wire between headlight switch and parking lamps.
