Power Circuit

  1. Use DVOM to check for battery voltage at terminals No. 1 and 48 (Pink/White wires). If battery voltage exists, go to next step. If battery voltage does not exist, repair open circuit in wire between ECM and fuse No. 28 in dashboard fuse block. See appropriate wiring diagram in WIRING DIAGRAMS article.
  2. Turn ignition on. Check for battery voltage between ECM terminal No. 60 (Yellow/Grey) and ground. If battery voltage does not exist, repair open circuit in wire between ECM and fuse No. 17 in dashboard fuse block.
