Start Signal System Test

  1. Locate ECM harness connector. ECM is located under center of instrument panel (connector is on driver's side). Turn ignition switch to START position. Measure voltage between ground and ECM harness connector terminal No. 20 (Black/Yellow wire). Battery voltage should be present in START position ONLY. Zero volts should be present in any other ignition switch position. If voltage is as specified, system is functioning properly.
  2. If voltage is not as specified, repair open harness or connectors between ignition switch, 7.5 amp fuse, and ECM sub-harness connector. If items are okay, check ECM terminals, harness and connectors for pushed-out, damaged, or corroded terminals. Repair or replace as necessary.
