Test 33B - Checking For Open 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.
- Disconnect Blue body controller connector. Body controller is located under left side of instrument panel. Check connector, and clean or repair connector as necessary.
- Using DRB-II in voltmeter mode, measure voltage of key-in light control circuit at Blue body controller connector terminal No. 19 (Yellow/Red wire). If voltage is more than 10 volts, replace body controller. If voltage is less than 10 volts, gain access to key-in ignition switch connector.NOTE: Key-in ignition switch connector MUST remain connected during following steps.
- Measure voltage of key-in light control circuit at key-in ignition switch connector terminal No. 4 (Yellow/Red wire). If voltage is more than 10 volts, repair open Yellow/Red wire. If voltage is less than 10 volts, go to next step.
- Measure voltage of courtesy light switched supply circuit at key-in ignition switch connector terminal No. 3 (Pink/Light Blue wire). If voltage is less than 10 volts, repair open Pink/Light Blue wire. If voltage is more than 10 volts, go to next step.
- Remove key-in light bulb. Inspect bulb and socket. If bulb and socket are not okay, repair or replace as necessary. If socket is okay, replace key-in light bulb.
