Circuit/System Testing

  1. Ignition OFF, disconnect the lead connector from the malfunctioning door handle assembly.
  2. Measure and check for less than 10 Ω between the ground lead listed below and ground.
    • A23D Door handle assembly - Driver terminal 8
    • A23P Door handle assembly - Passenger terminal 3
    • If greater than the value given above, test the ground lead for an open circuit/high resistance.
  3. Ignition ON, verify that the following scan tool parameters are inactive:
    • Driver door: Driver door-ajar switch
    • Passenger door: Passenger door-ajar switch
    • If not the specified value, test the signal circuit terminal for a short to ground. If it tests normal, replace the K84 Keyless Entry Control Module
  4. Install a 3 A fused jumper lead between the signal circuit listed below and ground. Verify with a scan tool that the driver door-ajar switch or passenger door-ajar switch is active.
    • A23D Door handle assembly - Driver terminal 7
    • A23P Door handle assembly - Passenger terminal 2
    • If not the specified value, test the signal circuit for a short to voltage or an open/high resistance. If the circuit tests normal, replace the K84 Keyless Entry Control Module.
  5. If all circuits function as normal, test or replace the door handle assembly.
