Circuit/System Testing

  1. Ignition OFF, disconnect the CRNK relay.
  2. Ignition OFF and scan tool disconnected, open and close the driver door, and wait 1 minute. Test for less than 5 Ω between the ground circuit terminal 85 and ground.
    • If greater than the specified range, test the ground circuit for an open/high resistance.
  3. Ignition OFF, connect a test lamp between the control circuit terminal 86 and the ground circuit terminal 85.
  4. With the transmission range selector in park, cycle the ignition switch between the OFF and START positions. The test lamp should turn ON and OFF when changing between the commanded states.
    • If the test lamp is always ON, test the control circuit for short to voltage. If the circuit tests normal, replace the ECM.
    • If the test lamp is always OFF, test the control circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the ECM.
  5. If all circuits test normal, test or replace the CRNK relay.
