Power Circuits

  1. Using DVOM, check for battery voltage between PCM power terminals and ground. See appropriate POWERTRAIN CONTROL MODULE CONNECTOR TERMINAL IDENTIFICATION  . See Figure . If battery voltage is not present, check for open fuse or fusible link. If fuse or fusible link is okay, go to next step.
  2. Turn ignition switch to ON position. Using DVOM, check for battery voltage at PCM ignition power terminals. If battery voltage is not present, check IGN fuse. If fuse is okay, check for open circuit between battery, ignition switch, and PCM ignition power terminals. If circuits are okay, check for faulty ignition switch.
  3. Check PCM START signal terminal. On vehicles with manual transmission, depress clutch pedal. On vehicles with automatic transmission, place gearshift lever in Park. Turn ignition switch to START position. Battery voltage should be present only when ignition switch is in START position.
  4. If voltage is not present, check CRANK fuse or fusible link between ignition switch and PCM START signal terminal. If fuse or fusible link is okay, check for open circuit between ignition switch and PCM START signal terminal, or check for faulty ignition switch.
