Vehicle: 2017 Chevrolet Cruze LT

Hey everyone, I'm dealing with an annoying issue on my 2017 Chevrolet Cruze LT.

Both the ABS light and the Traction Control light have illuminated on my dashboard, and they stay on constantly. I haven't noticed any immediate changes in braking performance, but I know these systems are important for safety.

I'm wondering what could be causing this. Is it usually a sensor, or could it be something more complex like the ABS module itself? Any advice on where to start looking would be great.

ClearTheCode admin answer:

The illumination of both the ABS and Traction Control lights on your 2017 Chevrolet Cruze LT typically indicates a fault within the Anti-lock Braking System (ABS) or the Electronic Stability Control (ESC) system, which relies heavily on ABS components.

Diagnostic Steps:

  1. Scan for ABS Codes: A standard OBD-II scanner might not read ABS-specific codes. You'll need a more advanced scanner capable of accessing the ABS module. Common codes related to this issue include C0035-C0050 (Wheel Speed Sensor circuit faults for various wheels), C0110 (Pump Motor Circuit Malfunction), or C0121 (Valve Relay Circuit Malfunction).
  2. Inspect Wheel Speed Sensors: These sensors are located at each wheel. Visually inspect the wiring harnesses leading to each sensor for any signs of damage, fraying, or corrosion. Also, check the sensor itself for physical damage or excessive dirt/debris buildup.
  3. Check Tone Rings: The wheel speed sensors read pulses from a magnetic tone ring on the axle or wheel hub. Inspect these rings for cracks, damage, or missing teeth.

Common Causes:

  • Faulty Wheel Speed Sensor: This is by far the most common cause. A sensor can fail internally, or its wiring can become damaged.
  • Damaged Tone Ring: A cracked or corroded tone ring can prevent the sensor from getting an accurate reading.
  • ABS Module Failure: Less common, but the ABS control module itself can fail, leading to these lights. This is usually a more expensive repair.
  • Wiring Issues: Open or short circuits in the ABS sensor wiring can also trigger the lights.

When to See a Shop: While the vehicle may still brake, the ABS and Traction Control systems are disabled, which compromises safety, especially in slippery conditions. It's recommended to have your Cruze diagnosed by a professional mechanic as soon as possible. They can use a specialized scan tool to pinpoint the exact wheel speed sensor or other component that is faulty, ensuring an accurate and efficient repair.
