Test 33A - Diagnosing Key-In Light Circuit
NOTE:
For connector terminal identification, see CONNECTOR IDENTIFICATION. For wiring diagrams, see WIRING DIAGRAMS
article in the ENGINE PERFORMANCE Section. Perform TEST VER - 1A after each repair.
CAUTION:
Always turn ignition switch to OFF position prior to disconnecting or connecting any module connector.
- Check courtesy lights. If courtesy lights are inoperative, go to TEST 28A. If courtesy lights are functioning properly, ensure all doors are closed. Turn ignition switch to OFF position. Wait one minute.
- If key-in light is on constantly, go to step 4). If key-in light is not on constantly, open left front door. If key-in light does not light, go to TEST 33B. If key-in light does light, turn ignition switch to ON position.
- If key-in light does not turn off, replace body controller. If key-in light does turn off, system is operating okay at this time.
- Access body controller. Body controller is located under left side of instrument panel. Disconnect Blue body controller connector. If key-in light does turn off, replace body controller. If key-in light does not turn off, disconnect key-in ignition switch connector. See Fig 1 .
- Check connector, and clean or repair connector as necessary. Using DRB-II in ohmmeter mode, measure resistance of key-in light control circuit at key-in ignition switch connector terminal No. 4 (Yellow/Red wire). If resistance is more than 5 ohms, replace ignition switch. If resistance is less than 5 ohms, repair short to ground in Yellow/Red wire.
