Circuit/System Testing

Verify DTC C0245 58 is not set.
- If the DTC is set
  Reprogram the K17 Electronic Brake Control Module.
- If the DTC is not set
Inspect the appropriate B5 Wheel Speed Sensor and encoder ring for contamination, metallic particles, physical damage, incorrect installation and the correct component.
- If contamination, physical damage, incorrect installation, or the wrong component is diagnosed
  Repair or replace the applicable component.
- If no contamination, physical damage, incorrect installation, or the wrong component is not diagnosed
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.
Test for less than 1 V between the K17 Electronic Brake Control Module harness connector terminals listed below and ground:
- B5LF Left Front Wheel Speed Sensor - terminal 8 and terminal 19
- B5RF Right Front Wheel Speed Sensor - terminal 4 and terminal 16
- B5LR Left Rear Wheel Speed Sensor - terminal 18 and terminal 31
- B5RR Right Rear Wheel Speed Sensor - terminal 17 and terminal 29
- If 1 V or greater
  Repair the short to voltage on the circuit.
- If less than 1 V
Ignition OFF.
Test for infinite resistance between the K17 Electronic Brake Control Module harness connector terminals listed below and ground:
- B5LF Left Front Wheel Speed Sensor - terminal 8 and terminal 19
- B5RF Right Front Wheel Speed Sensor - terminal 4 and terminal 16
- B5LR Left Rear Wheel Speed Sensor - terminal 18 and terminal 31
- B5RR Right Rear Wheel Speed Sensor - terminal 17 and terminal 29
- If less than infinite resistance
  Repair the short to ground on the circuit.
- If infinite resistance
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 Left Front Wheel Speed Sensor terminal 19
- B5RF Right Front Wheel Speed Sensor terminal 16
- B5LR Left Rear Wheel Speed Sensor terminal 31
- B5RR Right Rear Wheel Speed Sensor terminal 17
- If 2 Ω or greater
  Repair the open/high resistance in the circuit.
- If less than 2 Ω
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 Left Front Wheel Speed Sensor terminal 8
- B5RF Right Front Wheel Speed Sensor terminal 4
- B5LR Left Rear Wheel Speed Sensor terminal 18
- B5RR Right Rear Wheel Speed Sensor terminal 29
- If 2 Ω or greater
  Repair the open/high resistance in the circuit.
- If less than 2 Ω
Replace the B5 Wheel Speed Sensor.
