Circuit/System Testing

  1. Ignition OFF, disconnect the CRNK relay.
  2. Ignition OFF, test for less than 5 ohms between the relay ground circuit terminal 85 and ground.
    • If not within the specified range, test the ground circuit for an open/high resistance.
  3. Ignition OFF, connect a test lamp between the right rear control circuit terminal 86 and the ground circuit left front terminal 85. Turn the ignition to the start position. The test lamp should illuminate for a maximum of 10 seconds when the ignition is held in the start position.
    • If the test lamp is ON when the ignition is not in the start position, 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.
  4. If all circuits test normal, replace the CRNK relay.
