TEST 44A - Diagnosing Key-In Light Circuit
NOTE:
For connector terminal identification, see CONNECTOR IDENTIFICATION . For appropriate wiring diagram, see WIRING DIAGRAMS .
- Check courtesy lights. If courtesy lights are inoperative, perform TEST 10A . If courtesy lights are functioning properly, ensure all doors are closed. Turn ignition switch to OFF position. Wait one minute. Ensure dimmer control lever is in center position.
- If key light is on constantly, perform TEST 44B . If key light is not on constantly, turn ignition switch to ON position. Using DRB-II, actuate key in light test. If key light flashes off then on, perform TEST 44C . If key light does not flash off then on, using DRB-II, stop key light test.
- Disconnect key ignition switch connector. See Figure. Check connector, and clean or repair connector as necessary. Place DRB-II in voltmeter mode. Probe Pink/Light Blue wire of key-in light connector. If voltage is less than 10 volts, repair open Pink/Light Blue wire. Perform VERIFICATION TEST - VERIFICATION OF REPAIRS .
- If voltage is more than 10 volts, remove key light bulb. Inspect bulb and socket. If bulb and socket are not okay, repair replace as necessary. Perform VERIFICATION TEST - VERIFICATION OF REPAIRS . If bulb and socket are okay, reconnect key-in light connector.
- Access body controller. Body controller is located under left side of instrument panel. Ensure DRB-II is in voltmeter mode. Probe terminal No. 22 (Yellow/Red wire) of body controller Blue connector. If voltage is less than 10 volts, repair open Yellow/Red wire. Perform VERIFICATION TEST - VERIFICATION OF REPAIRS . If voltage is more than 10 volts, replace body controller. Perform VERIFICATION TEST - VERIFICATION OF REPAIRS .
