Circuit/System Testing

WARNING: This page is about a different car, the 2018 Chevrolet Suburban 3500 HD. However, it is still accessible from the selected car via links, so may be relevant.
  1. Ignition OFF and all vehicle systems OFF, disconnect the harness connectors at the appropriate B5 Wheel Speed Sensor and the harness connector at the K17 Electronic Brake Control Module, ignition ON.
  2. Test for less than 1 V between the appropriate K17 Electronic Brake Control Module harness connector terminals listed below and ground:
    • B5LF Wheel Speed Sensor - Left Front - terminal 35 and terminal 36
    • B5LR Wheel Speed Sensor - Left Rear - terminal 29 and terminal 30
    • B5RF Wheel Speed Sensor - Right Front - terminal 10 and terminal 11
    • B5RR Wheel Speed Sensor - Right Rear - terminal 3 and terminal 4
    • If 1 V or greater 

      Repair the short to voltage on the circuit.

    • Go to next step: If less than 1 V 
  3. Ignition OFF.
  4. Test for infinite resistance between the K17 Electronic Brake Control Module harness connector terminals listed below and ground:
    • B5LF Wheel Speed Sensor - Left Front - terminal 35 and terminal 36
    • B5LR Wheel Speed Sensor - Left Rear - terminal 29 and terminal 30
    • B5RF Wheel Speed Sensor - Right Front - terminal 10 and terminal 11
    • B5RR Wheel Speed Sensor - Right Rear - terminal 3 and terminal 4
    • If less than infinite resistance 

      Repair the short to ground on the circuit.

    • Go to next step: If infinite resistance 
  5. Test for less than 2 Ω between the B5 Wheel Speed Sensor harness connector terminal 1 and the K17 Electronic Brake Control Module harness connector terminal listed below:
    • B5LF Wheel Speed Sensor - Left Front - terminal 35
    • B5LR Wheel Speed Sensor - Left Rear - terminal 29
    • B5RF Wheel Speed Sensor - Right Front - terminal 10
    • B5RR Wheel Speed Sensor - Right Rear - terminal 3
    • If 2 Ω or greater 

      Repair the open/high resistance in the circuit.

    • Go to next step: If less than 2 Ω 
  6. Test for less than 2 Ω between the B5 Wheel Speed Sensor harness connector terminal 2 and the K17 Electronic Brake Control Module harness connector terminal listed below:
    • B5LF Wheel Speed Sensor - Left Front - terminal 36
    • B5LR Wheel Speed Sensor - Left Rear - terminal 30
    • B5RF Wheel Speed Sensor - Right Front - terminal 11
    • B5RR Wheel Speed Sensor - Right Rear - terminal 4
    • If 2 Ω or greater 

      Repair the open/high resistance in the circuit.

    • Go to next step: If less than 2 Ω 
  7. Replace the B5 Wheel Speed Sensor.
  8. Verify the DTC does not set while operating the vehicle within the Conditions for Running the DTC.
    • If the DTC sets 

      Replace the K17 Electronic Brake Control Module.

    • Go to next step: If the DTC does not set 
  9. All OK.
