Circuit/System Testing

  1. Ignition OFF, disconnect the harness connector at the inside rearview mirror.
  2. Test for less than 10 ohms between the low reference circuit terminal 8 and ground.
    • If greater than the specified range, test the ground circuit for an open/high resistance.
  3. Ignition ON, verify that a test lamp illuminates between the ignition circuit terminal 13 and ground.
    • If the test lamp does not illuminate, test the ignition circuit for a short to ground or an open/high resistance.
  4. Ignition ON, park brake applied, vehicle in REVERSE, verify that a test lamp illuminates between the backup lamp control circuit terminal 9 and ground.
    • If the test lamp does not illuminate, test the control circuit for a short to ground or an open/high resistance. If the circuit tests normal, refer to BACKUP LAMPS MALFUNCTION .
  5. If all circuits test normal, test or replace the inside rearview mirror.
