Rearview Camera System Does Not Display

  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.
