Circuit/System Testing

NOTE: If any of the symptom codes 0F, 18 or 5A are set, refer to the Diagnostic Fault Information table for possible mechanical faults or conditions.
  1. Ignition OFF, disconnect the harness connector at the appropriate B5 Wheel Speed Sensor. It may take up to 2 min for all vehicle systems to power down.
  2. Test for less than 5 Ω between the signal circuit terminal 2 and ground.
    • If 5 Ω or greater 
    1. Ignition OFF, disconnect the harness connector at the K17 Electronic Brake Control Module.
    2. 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, replace the K17 Electronic Brake Control Module.
    • If less than 5 Ω 
  3. Ignition ON.
  4. Test for greater than 11 V between the ignition circuit terminal 1 and ground.
    • If less than 11 V 
    1. Ignition OFF, disconnect the harness connector at the K17 Electronic Brake Control Module.
    2. Test for infinite resistance between the ignition 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 ignition circuit end to end.
      • If 2 Ω or greater, repair the open/high resistance in the circuit.
      • If less than 2 Ω, replace the K17 Electronic Brake Control Module.
    • If 11 V or greater 
  5. Install a 3 A fused jumper wire at the ignition circuit terminal 1, ignition ON.
  6. Verify the scan tool Wheel Speed Sensor parameter changes while rapidly tapping the fused jumper wire to the signal circuit terminal 2.
    • If the parameter does not change 
    1. Ignition OFF, disconnect the harness connector at the K17 Electronic Brake Control Module, ignition ON.
    2. Test for less than 1 V between the signal circuit and ground.
      • If 1 V or greater, repair the short to voltage on the circuit.
      • If less than 1 V
    3. Replace the K17 Electronic Brake Control Module.
    • If the parameter changes 
  7. Test or replace the B5 Wheel Speed Sensor.
