Circuit/System Testing (Object Detection And Pedestrian Protection System)

2015 Chevrolet Express 2500 Base, Van Cargo Extended, 6.0L Eng VIN BSECTION Circuit/System Testing (Object Detection And Pedestrian Protection System)
NOTE:

Circuit/System Verification must be performed before Circuit/System Testing.

  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 10 Ω or greater 

      Test for less than 2 Ω in the ground circuit end to end.

    • If 2 Ω or greater, repair the open/high resistance in the circuit.
    • If less than 2 Ω, repair the open/high resistance in the ground connection.
    • If less than 10 Ω 
  3. Ignition ON.
  4. Verify a test lamp illuminates between the ignition circuit terminal 6 and ground.
    • If the test lamp does not illuminate 
    1. Ignition OFF.
    2. Test for less than 2 Ω in the ignition circuit end to end.
      • If 2 Ω or greater, repair the open/high resistance in the circuit.
      • If less than 2 Ω, verify the fuse is OK and there is voltage at the fuse.
    3. If the circuit tests normal, test or replace the RUN/CRNK Relay.
    • If the test lamp illuminates 
  5. Engine running, park brake applied, transmission in REVERSE.
  6. Verify a test lamp illuminates between the control circuit terminal 3 and ground.
    • If the test lamp does not illuminate 
    1. Ignition OFF, disconnect the X5 harness connector at the Body Control Module.
    2. Test for infinite resistance between the control circuit and ground.
      • If less than infinite resistance, repair the short to ground on the circuit.
      • If infinite resistance
    3. Test for less than 2 Ω in the control circuit end to end.
      • If 2 Ω or greater, repair the open/high resistance in the circuit.
      • If less than 2 Ω, replace the Body Control Module.
    • If the test lamp illuminates 
  7. Ignition OFF, disconnect the X4 harness connector at the Radio, ignition ON.
  8. Test for less than 1 V between the signal circuit terminal listed below and ground:
    • Signal (+) circuit terminal 1 at the Rearview Camera.
    • Signal (-) circuit terminal 4 at the Rearview Camera.
    • If 1 V or greater 

      Repair the short to voltage on the circuit.

    • If less than 1 V 
  9. Test for infinite resistance between the signal circuit terminal listed below and ground:
    • Signal (+) circuit terminal 1 at the Rearview Camera.
    • Signal (-) circuit terminal 4 at the Rearview Camera.
    • If less than infinite resistance 

      Repair the short to ground on the circuit.

    • If infinite resistance 
  10. Test for less than 2 Ω in the signal (+) circuit end to end.
    • If 2 Ω or greater 

      Repair the open/high resistance in the circuit.

    • If less than 2 Ω 
  11. Test for less than 2 Ω in the signal (-) circuit end to end.
    • If 2 Ω or greater 

      Test the signal circuit for an open/high resistance.

    • If less than 2 Ω 
  12. Replace the Rearview Camera.
  13. Engine running, transmission in REVERSE, verify a clear rear vision image is displayed on the Radio.
    • If a clear rear vision image is not displayed on the Radio 

      Replace the Radio.

    • If a clear rear vision image displayed on the Radio 
  14. All Ok.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

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