Test 49C - Repairing Body Controller Battery Power Supply

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.
  1. Ensure all courtesy lights are off. Reconnect Blue body controller connector. Close all doors. Using DRB-II in ohmmeter mode, check resistance of fused battery feed circuit at fuse No. 3 (Pink wire). If resistance is more than 5 ohms, replace fuse No. 3.
  2. If resistance is less than 5 ohms, disconnect left pod switch connector. Check resistance of fused battery feed circuit at fuse No. 3 (Pink wire). If resistance is more than 5 ohms, go to step 4).
  3. If resistance is less than 5 ohms, check resistance of switched battery feed circuit at left pod switch Black connector terminal No. 5 (Pink/Light Blue wire). 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, repair short to ground in Pink wire and replace fuse No. 3.
  4. Disconnect Blue body controller connector. Check resistance of fused battery feed circuit at 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. Check resistance of fused battery feed circuit at fuse No. 3 (Pink wire). If resistance is more than 5 ohms, replace instrument cluster and fuse No. 3.
  6. If resistance is less than 5 ohms, disconnect radio. Check resistance of fused battery feed circuit at fuse No. 3 (Pink wire). If resistance is more than 5 ohms, replace radio and fuse No. 3.
  7. If resistance is less than 5 ohms and vehicle is not equipped with compass/mini trip module, repair short to ground in Pink wire. If resistance is less than 5 ohms and vehicle is equipped with compass/mini trip module, disconnect compass/mini trip module 4-pin connector.
  8. Check resistance of fused battery feed circuit at fuse No. 3 (Pink wire). If resistance is more than 5 ohms, replace courtesy light assembly in overhead console and fuse No. 3.
  9. If resistance is less than 5 ohms, disconnect compass/mini trip module 13-pin connector. Check resistance of fused battery feed circuit at fuse No. 3 (Pink wire). If resistance is more than 5 ohms, replace compass/mini trip module and fuse No. 3. If resistance is less than 5 ohms, repair short to ground in Pink wire and replace fuse No. 3.
