Circuit/System Testing

  1. Ignition OFF, disconnect the harness connector at the key capture solenoid.
  2. Test for less than 5 ohms between the ground circuit terminal 1 and ground.
    • If greater than the specified range, test the ground circuit for an open/high resistance.
  3. Connect a test lamp between the control circuit terminal 2 and the ground circuit terminal 1.
  4. Command the Key Capture Solenoid ON and OFF with a scan tool. 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 RCDLR.
    • If the test lamp is always OFF, test the control circuit for short to ground or an open/high resistance. If the circuit tests normal, replace the RCDLR.
  5. If all circuits tests normal, test or replace the key capture solenoid.
