Interior Light Test 6A - Key-In Light Inoperative
NOTE:
Perform INTERIOR 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.
- 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 illuminates and then, after 30 seconds, turns off, system is operating properly. If key-in light does not illuminate as described and courtesy lights do not come on, open left front door. If courtesy lights still do not illuminate, go to DOOR AJAR TEST 3A . If key-in light does not operate as described and courtesy lights do illuminate 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 Body Control Module (BCM). BCM is mounted to junction block. See Figure in CHIME TEST 2A.
- Stop key-in light actuation and remove key-in bulb. See STEERING COLUMN SWITCHES article in the ACCESSORIES & ELECTRICAL section. 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 external voltmeter, measure voltage between ground and terminal No. 1 (Pink/White wire) on key-in light 2-pin connector. If voltage is more than 10 volts, go to next step. If voltage is 10 volts or less, repair open Pink/White wire between fuse No. 5 (10-amp) 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 external voltmeter, measure voltage between ground and terminal No. 7 (Yellow/Red wire) on instrument panel (BCM) 10-pin connector. If voltage is more than 10 volts, replace BCM. If voltage is 10 volts or less, repair open in Yellow/Red wire between BCM and key-in light.
