Circuit/System Testing

  1. Ignition ON, verify the mirror direction changes as the switch is activated. The mirror should change between UP, DOWN, LEFT, RIGHT.
    • If the function does not perform as specified, replace the DDM.
  2. Ignition OFF, disconnect the appropriate outside rearview mirror driver or passenger harness connectors.
  3. Ignition OFF, test for less than 1.0 ohm of resistance at each mirror motor control circuit between the outside rearview mirror driver or passenger harness connectors and ground.
    • If greater than the specified range, test the appropriate mirror motor control circuit for a short to voltage or an open/high resistance. If the circuit tests normal, replace the appropriate door control module.
  4. Connect a test lamp between mirror motor UP and DOWN control circuit terminal 1 connector X3 and ground circuit terminal 10 connector X5 of the PDM or DDM.
  5. Command the appropriate mirror to the UP and DOWN positions. The test lamp should turn ON when commanding the UP and DOWN states.
    • If the test lamp remains OFF during either of the commands, test for a short to ground on the control circuit. If the circuit tests normal, replace the appropriate door control module.
  6. Connect a test lamp between mirror motor LEFT and RIGHT control circuit terminal 1 connector X3 and ground circuit terminal 2.
  7. Command the appropriate mirror to the LEFT and RIGHT positions. The test lamp should turn ON when commanding the LEFT and RIGHT states.
    • If the test lamp remains OFF during either of the commands, test for a short to ground on the control circuit. If the circuit tests normal, replace the appropriate door control module.
  8. If all circuits test normal, test or replace the appropriate outside rearview mirror.
