2016 Dodge Durango Citadel - ABS and Traction Control Lights On, Brake Issues

Vehicle: 2016 Dodge Durango Citadel

Hi everyone,

I'm having a problem with my 2016 Dodge Durango Citadel (V6, 3.6L) with about 80,000 miles. The ABS light and the Traction Control light both came on simultaneously a few days ago, and they've stayed on since. I also feel like the brakes are a bit 'soft' or less responsive than usual, though they still work.

I tried scanning it with my basic OBD-II reader, but it's not showing any 'P' codes. I know ABS/Traction Control issues often throw 'C' codes, which my scanner can't read. I'm wondering if this is a wheel speed sensor issue or something more serious with the ABS module.

Has anyone else dealt with this on their Durango? What should I be looking for? Thanks for your help!

ClearTheCode admin answer:

When both the ABS and Traction Control lights illuminate on your 2016 Dodge Durango, it almost always indicates a fault within the Anti-lock Braking System (ABS). Since the Traction Control System (TCS) relies heavily on the ABS wheel speed sensors for its operation, a fault in the ABS will typically disable TCS as well. The 'soft' brake pedal feeling could be related or a separate issue that needs attention.

Here are the most common causes for these warning lights:

  1. Wheel Speed Sensor (WSS) Failure: This is by far the most frequent cause. Each wheel has a sensor that monitors its rotational speed. If a sensor fails, becomes dirty, or its wiring is damaged, the ABS module loses critical data, triggering the lights.
  2. Damaged ABS Tone Ring: The tone ring (or reluctor ring) is a toothed ring that the WSS reads. If it's cracked, corroded, or damaged, the sensor will get incorrect readings.
  3. ABS Module Failure: Less common, but the ABS control module itself can fail. This is a more expensive repair.
  4. Low Brake Fluid: While usually indicated by a separate brake warning light, extremely low fluid can sometimes affect ABS operation, though it's more likely to cause a spongy pedal.
  5. Wiring Issues: Damaged or corroded wiring to any of the wheel speed sensors or the ABS module can cause intermittent or permanent faults.

Diagnostic Steps:

  • Professional Scan: As you noted, a basic OBD-II scanner won't read 'C' (Chassis) codes. You'll need an advanced scanner that can communicate with the ABS module to retrieve specific diagnostic trouble codes (DTCs) like C0031 (Left Front Wheel Speed Sensor Circuit) or similar. This is the most crucial first step.
  • Visual Inspection: Once you know which wheel is affected (if a WSS code is present), visually inspect the wheel speed sensor and its wiring at that wheel. Look for physical damage, corrosion, or loose connections. Also, check the tone ring for damage or debris.
  • Brake Fluid Check: Verify your brake fluid level is at the 'MAX' line. If it's low, top it off and check for leaks.

When to see a shop:

It's highly recommended to take your Durango to a professional mechanic or a Dodge dealership. They have the necessary diagnostic tools to read the specific 'C' codes from the ABS module, which will pinpoint the exact problem. Driving with a compromised ABS system can affect your vehicle's braking performance, especially in emergency situations or on slippery roads. Addressing the issue promptly is important for your safety.
