Interior Light Test 6A - Key-In Light Inoperative
NOTE:
Perform INTERIOR LIGHT TEST 1A
before proceeding with this test. For connector terminal identification, see CONNECTOR IDENTIFICATION in BODY CONTROL COMPUTER INTRODUCTION. Perform TEST VER-1A
after each repair.
CAUTION:
Always turn ignition switch to OFF position prior to disconnecting or connecting any module connector.
- Turn ignition off. Close all doors and wait one minute. Open and close left front door while watching key-in light. If key-in light comes on and then, after 30 seconds, goes off, system is operating properly. If key-in light does not operate as described and courtesy lights do not come on when left front door is opened, go to DOOR AJAR TEST 3A . If key-in light does not operate as described and courtesy lights do come on when left front door is opened, go to next step.
- Turn ignition on. Using scan tool, actuate key-in light. If key-in light does not flash on and off, go to next step. If key-in light flashes on and off, replace BCM.
- Stop key-in light actuation and remove key-in bulb. See STEERING COLUMN SWITCHES article in ACCESSORIES & EQUIPMENT. Inspect key-in bulb and socket. If key-in bulb and socket are okay, go to next step. If key-in bulb is open or socket is damaged, repair socket or replace bulb as necessary.
- Install key-in bulb. Disconnect key-in light 2-pin connector and ensure connector is clean and not damaged. Using scan tool in voltmeter mode, check voltage on key-in light 2-pin connector terminal No. 1 (Pink/White wire). If voltage is more than 10 volts, go to next step. If voltage is less than 10 volts, repair open Pink/White wire between fuse No. 5 and key-in light connector.
- Reconnect key-in light 2-pin connector. Disconnect instrument panel 10-pin connector at BCM. Ensure connector is clean and not damaged. Using scan tool in voltmeter mode, check voltage on instrument panel 10-pin connector terminal No. 7 (Yellow/Red wire). If voltage is more than 10 volts, replace BCM. If voltage is less than 10 volts, repair open in Yellow/Red wire between BCM and key-in light.
