Test 28B - Diagnosing Courtesy Light Battery Feed 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.
NOTE: Ensure vanity mirror, glove box and under seat lights are off. All doors MUST be closed during the following test steps.
CAUTION: Always turn ignition switch to OFF position prior to disconnecting or connecting any module connector.
  1. Using DRB-II in ohmmeter mode, measure resistance of fused battery feed circuit at fuse No. 3 (Pink wire). If resistance is less than 5 ohms, replace fuse. If resistance is more than 5 ohms, disconnect Black left pod switch connector.
  2. Measure resistance at fuse No. 3 (Pink wire). If resistance is less than 5 ohms, go to step 4). If resistance is more than 5 ohms, measure resistance of switched battery feed circuit at Black left pod switch connector terminal No. 5 (Pink/Light Blue wire).
  3. If resistance is less than 5 ohms, repair short to ground in Pink/Light Blue wire and replace fuse No. 3. If resistance is more than 5 ohms, replace left pod switch and fuse No. 3.
  4. Disconnect body controller connectors. Body controller is located under left side of instrument panel. Ensure probe is still connected to fuse No. 3 (Pink wire). If resistance is more than 5 ohms, replace body controller and fuse No. 3.
  5. If resistance is less than 5 ohms, disconnect instrument cluster connector. Measure resistance at fuse No. 3 (Pink wire). If resistance is less than 5 ohms, repair or replace instrument cluster and replace fuse. If resistance is more than 5 ohms, disconnect radio.
  6. Measure resistance at fuse No. 3 (Pink wire). If resistance is less than 5 ohms, replace radio and fuse. If resistance is more than 5 ohms, repair short to ground in Pink wire and replace fuse No. 3.
