2009 Saturn Vue XR, 3.6 7, AWDFACTORY OEM SERVICE PROCEDURE

Circuit/System Testing

Rearview Camera System Always On

  1. Ignition OFF, disconnect the harness connector at the rearview camera.
  2. Engine running, transmission in PARK, verify a test lamp does not illuminate between the control circuit terminal 3 and ground.
    • If the test lamp illuminates, test the control circuit for a short to voltage. If the circuit tests normal, refer to Backup Lamps Malfunction .
  3. If all circuits test normal, test or replace the rearview camera.

Rearview Camera System Does Not Display

  1. Ignition OFF, disconnect the harness connector at the rearview camera.
  2. Test for less than 10 Ξ© between the ground circuit terminal 5 and ground.
    • If greater than the specified range, test the ground circuit for an open/high resistance.
  3. Engine running, verify a test lamp illuminates between the ignition circuit terminal 6 and ground.
    • If the test lamp does not illuminate, test the ignition circuit for a short to ground or an open/high resistance.
  4. Park brake applied, transmission in REVERSE, test for B+ between the B+ circuit terminal 3 and ground.
    • If less than the specified value, test the B+ circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the BCM.
  5. Test for less than 1 V between the following signal circuit terminals at the rearview camera harness connector and ground:
    • Signal (+) circuit terminal 1
    • Signal (-) circuit terminal 4
    • If greater than the specified range, test the signal circuit for a short to voltage.
  6. Test for infinite resistance between the following circuit terminals at the rearview camera harness connector and ground:
    • Signal (+) circuit terminal 1
    • Signal (-) circuit terminal 4
    • If not the specified value, test the circuit for a short to ground.
  7. Test for less than 10 Ξ© between the shield ground circuit terminal 2 and ground.
    • If greater than the specified range, test the shield ground circuit for an open/high resistance.
  8. Ignition OFF, disconnect the harness connector at the inside rearview mirror.
  9. Test for less than 2 Ξ© between the signal (+) circuit terminal 1 at the rearview camera harness connector and the signal (+) circuit terminal 6 at the inside rearview mirror harness connector.
    • If greater than the specified range, test the signal circuit for an open/high resistance.
  10. Test for less than 2 Ξ© between the signal (-) circuit terminal 4 at the rearview camera harness connector and the signal (-) circuit terminal 7 at the inside rearview mirror harness connector.
    • If greater than the specified range, test the signal circuit for an open/high resistance.
  11. If all circuits test normal, test or replace the rearview camera.
  12. Engine running, transmission in REVERSE, verify a clear rear vision image is displayed on the inside rearview mirror.
    • If a clear rear vision image is not displayed, replace the inside rearview mirror.

  • β€’ You smell fuel, burning insulation, or see smoke.
  • β€’ Brakes feel soft, pull hard to one side, or make grinding noises.
  • β€’ The engine overheats, stalls repeatedly, or misfires under load.
  • β€’ You are missing required tools, torque specs, or safe lifting equipment.
  • β€’ You are not confident in the next step or safety outcome.
