Interior Lights Test 2A - Courtesy Lights Inoperative From Any Switch
NOTE:
Perform INTERIOR LIGHTS TEST 1A
before proceeding. For connector terminal ID, see CONNECTOR IDENTIFICATION
and WIRING DIAGRAM. Perform TEST VER-1A
after each repair.
CAUTION:
Always turn ignition switch to OFF position prior to disconnecting any module connector. Ensure all connectors are clean and tight.
- Using scan tool in voltmeter mode, probe both sides of courtesy light fuse No. 16 (10-amp) in junction block. Junction block is located behind right kick panel. If voltage is more than 10 volts on both sides of fuse, go to step 3). If voltage is less than 10 volts on fused side (Pink wire) and more than 10 volts on B+ side (Red/Yellow wire), go to next step.
- Remove fuse No. 16. Using scan tool in ohmmeter mode, probe B+ (Red/Yellow wire) side of fuse No. 16. If resistance is less than 5 ohms, repair short to ground in Red/Yellow wire. If resistance is 5 ohms or more, replace fuse No. 16.
- Turn ignition off. Remove courtesy light relay in junction block. See Fig 1 . Using scan tool in voltmeter mode, probe courtesy light relay connector terminal No. 86 (Pink wire). If voltage is less than 10 volts, replace junction block. If voltage is 10 volts or more, go to next step.
- Using scan tool in ohmmeter mode, probe courtesy light relay connector terminal No. 87 (ground). If resistance is more than 50 ohms, repair open in ground circuit. If resistance is 50 ohms is less, go to next step.
- Connect a jumper wire between courtesy light relay connector terminals No. 30 (Yellow wire) and No. 87 (ground). If courtesy lights do not illuminate, repair open in Yellow wire. If courtesy lights illuminate, go to next step.
- Ensure right front door is open. Using scan tool, check status of right front door ajar switch. If scan tool does not display RF DOOR AJAR: CLOSED, go DOOR AJAR TEST 5A . If scan tool displays RF DOOR AJAR: CLOSED, go to next step.
- Using scan tool in ohmmeter mode, probe courtesy light relay connector terminal No. 85 (Brown/Light Green wire). If resistance is more than 80 ohms, repair open in Brown/Light Green wire. If resistance is 80 ohms or less, replace courtesy light relay.
