Vehicle: 2017 Volvo XC60 T5 Dynamic

Hello everyone,

I'm having an issue with my 2017 Volvo XC60 T5 Dynamic. Both the ABS warning light and the Traction Control warning light (the one that looks like a car skidding) have illuminated on my dashboard. They came on simultaneously a couple of days ago and haven't gone off since.

I haven't noticed any immediate changes in braking performance, but I'm concerned about driving with these critical safety systems disabled. I did notice a slight shudder when braking hard a few weeks ago, but it went away.

What could be causing this? Is there a common sensor issue or something I should be aware of for this model year? Any advice on what to check or what OBD codes might be relevant?

ClearTheCode admin answer:

When both the ABS and Traction Control (TRACS) lights illuminate, it indicates a fault within the vehicle's anti-lock braking system, which often shares components with the traction control system. Here are the most common causes for your 2017 Volvo XC60:

  1. Wheel Speed Sensor Failure: This is by far the most frequent culprit. Each wheel has a sensor that monitors its rotational speed. If a sensor becomes dirty, damaged, or fails electronically, the ABS/TRACS module loses critical data, triggering the warning lights. Common OBD-II codes related to this include C0031 (Left Front Wheel Speed Sensor), C0034 (Right Front Wheel Speed Sensor), C0037 (Left Rear Wheel Speed Sensor), C0040 (Right Rear Wheel Speed Sensor), or similar codes indicating a circuit malfunction.
  2. ABS Module Failure: Less common but more serious, the ABS control module itself can fail. This module processes data from the wheel speed sensors and controls the ABS pump. A faulty module can lead to various ABS/TRACS-related codes, often starting with 'C'.
  3. Low Brake Fluid Level: While usually triggering a separate brake warning light, extremely low brake fluid can sometimes affect ABS/TRACS operation, as these systems rely on proper hydraulic pressure.
  4. Wiring Issues: Damaged wiring or connectors leading to the wheel speed sensors or the ABS module can interrupt communication and trigger the lights.
  5. Faulty ABS Pump/Motor: The pump is responsible for modulating brake pressure during ABS activation. If it fails, the system will be disabled.

When to See a Shop:

  • Immediate Diagnostic Scan: You need to get your vehicle to a mechanic or a shop with a diagnostic scanner capable of reading ABS-specific codes (not just generic engine codes). This is crucial for pinpointing the exact cause. The codes will guide the technician directly to the faulty component.
  • Safety Implications: While your regular brakes may still function, the ABS and Traction Control systems are disabled. This means your wheels could lock up under hard braking, and you won't have assistance preventing wheel spin on slippery surfaces. Drive cautiously, especially in adverse weather conditions.
  • Professional Repair: Repairing ABS/TRACS issues often involves replacing sensors, modules, or wiring, which requires specific tools and expertise. It's not typically a DIY job.
