Circuit/System Testing

  1. Ignition OFF, disconnect the harness connector at the S3 transmission shift lever.
  2. Ignition OFF, test for less than 10 Ω between the ground circuit terminal 2 and ground.
    • If greater than the specified range, test the ground circuit for an open/high resistance.
  3. Install a test lamp between the ground circuit terminal 2 and the control circuit terminal 4.
  4. Ignition ON, command the scan tool Shift Lock Solenoid Actuator ON and OFF. 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 K9 body control module.
    • 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 K9 body control module.
  5. If all circuits test normal, test or replace the S3 transmission shift lever.
