Circuit/System Testing

  1. Ignition OFF, disconnect the X1 harness connector at the outside rearview mirror.
  2. Connect a test lamp between the control circuit terminal 1 and the control circuit terminal 2.
  3. Command the mirrors to extend and retract using the power folding switch. The test lamp turn ON and OFF when changing between the commanded states.
    • If the test lamp is always ON, test both control circuits for a short to voltage. If the circuit tests normal, replace the appropriate door switch.
