Wheel Speed Sensor Noise/Codes
This bulletin applies to 2014-2017 Chevy Corvettes. The ABS, Service Traction Control System and/or Service Stabilitrak telltale lights may be on. During initial scan for EBCM module DTCs, you may find one or more DTC C0035-C0050 with specific symptom bytes 18, 5A, 0F.
You may notice a brief and intermittent noise, click, ratchet, grind or ABS pump motor noises typically heard from inside the vehicle at parking lot speeds. A flashing Traction Control or Stabilitrak telltale may be evident at low speeds. These conditions may be caused by single or multiple pieces of ferrous metallic debris stuck to the wheel speed sensor magnetic encoder ring. Inspect and clean debris from the encoder ring.
