  1. Check for battery voltage at ECM terminal No. 26 (Red wire). If battery voltage exists, go to next step. If battery voltage does not exist, repair Red wire between ECM and fuse panel.
  2. Turn ignition on. Battery voltage should exist between ECM terminal No. 27 (Yellow/White wire) and ground. If battery voltage does not exist, repair open circuit in Yellow/White wire.
