Rearview Camera System Does Not Display

WARNING: This page is about a different car, the 2009 Saturn Outlook, 2009 GMC Acadia, 2009 Chevrolet Traverse, and 2009 Buick Enclave. However, it is still accessible from the selected car via links, so may be relevant.
  1. Ignition OFF, disconnect the harness connector at the rearview camera.
  2. Test for less than 10 Ω between the ground circuit terminal 5 and ground.
    • If greater than the specified range, test the ground circuit for an open/high resistance.
  3. Ignition ON, 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, verify a test lamp illuminates between the control circuit terminal 3 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, replace the BCM.
  5. Ignition OFF, disconnect the harness connector at the inside rearview mirror.
  6. Ignition ON, 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.
  7. 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.
  8. Test for less than 2 Ω 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.
  9. Test for less than 2 Ω 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.
  10. If all circuits test normal, test or replace the rearview camera.
  11. Ignition ON, 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.
