ABS and Traction Control Lights On - 2016 Dodge Journey

Vehicle: 2016 Dodge Journey SXT

Hey forum,

Both my ABS and Traction Control warning lights suddenly illuminated on the dashboard of my 2016 Dodge Journey SXT. The brakes seem to be working okay, and I haven't noticed any immediate changes in driving, but I know these lights are serious.

Is this typically a simple sensor issue, or could it be something more complex like the ABS module itself? Are there any common OBD codes associated with these lights on a Dodge Journey that I should look for if I get it scanned? Any advice on where to start troubleshooting would be great.

Thanks in advance!

ClearTheCode admin answer:

When both the ABS and Traction Control (TC) lights illuminate, it usually indicates a fault within the Anti-lock Braking System, as the TC system relies heavily on ABS components and sensors. While your brakes feel normal, the safety features of ABS and TC are likely disabled.

Here are the most common causes and what to look for on your 2016 Dodge Journey SXT:

  1. Wheel Speed Sensor (WSS) Failure: This is by far the most common culprit. Each wheel has a sensor that monitors its rotational speed. If one fails, the ABS/TC module loses crucial data, triggering the lights. Damage, dirt, or a faulty sensor can cause this.
  2. Damaged Wiring or Connectors: The wiring leading to the wheel speed sensors or the ABS module can get corroded, frayed, or disconnected, leading to intermittent or constant faults.
  3. Low Brake Fluid Level: While less common for both lights, extremely low brake fluid can sometimes trigger warnings related to the braking system.
  4. ABS Module Failure: The ABS control module itself can fail. This is a more expensive repair but is less common than a sensor issue.
  5. Tone Ring Damage: The tone ring (or reluctor ring) is a toothed ring that the wheel speed sensor reads. If it's cracked, bent, or clogged with debris, it can cause erratic readings.

Common OBD/ABS Codes: When you get the vehicle scanned with an ABS-capable scanner (not just a basic OBD-II scanner), you might see codes like:

  • C0031 - C0034: (Left Front, Right Front, Left Rear, Right Rear) Wheel Speed Sensor Circuit A Malfunction.
  • C0035 - C0038: (Left Front, Right Front, Left Rear, Right Rear) Wheel Speed Sensor Circuit B Malfunction.
  • C0040 - C0044: Specific sensor performance issues.
  • C0020: ABS Pump Motor Control Circuit Malfunction (indicates ABS module or pump issue).

When to see a shop:

  • Immediately: While the brakes might feel normal, you've lost critical safety features. In an emergency braking situation, your wheels could lock up, and the traction control won't prevent wheel spin.
  • Have the vehicle scanned with an advanced OBD-II scanner that can read ABS codes. This will pinpoint which sensor or circuit is at fault.
  • A professional mechanic can diagnose the exact cause, whether it's a simple sensor replacement, wiring repair, or a more involved ABS module service.
