ABS and Traction Control Lights On - 2022 Ford Edge ST, Spongy Pedal

Vehicle: 2022 Ford Edge ST

Hey Ford community,

I'm having an issue with my 2022 Ford Edge ST that just popped up. Both the ABS warning light and the Traction Control light came on simultaneously on my dashboard. The car has about 25,000 miles on it.

Beyond the lights, I've noticed that the brake pedal sometimes feels a bit spongy or less firm than usual, though the actual braking performance doesn't seem drastically reduced. I haven't heard any strange noises, but it's definitely concerning to have these critical warning lights illuminated. Could this be a simple sensor issue, or something more serious with the ABS module itself? Any advice on what to check or common OBD codes for this would be really helpful!

ClearTheCode admin answer:

The simultaneous illumination of your ABS and Traction Control lights, along with a spongy brake pedal, on your 2022 Ford Edge ST, indicates a problem within the anti-lock braking system (ABS) or traction control system. These systems are interconnected, so a fault in one often triggers the other.

Here are the most common causes:

  1. Wheel Speed Sensors: These sensors monitor the rotational speed of each wheel. If one sensor fails, becomes dirty, or its wiring is damaged, the ABS/TCS system loses crucial data, triggering the lights. Common OBD-II codes for this include C0031 (Left Front Wheel Speed Sensor), C0034 (Right Front), C0037 (Left Rear), and C003A (Right Rear).
  2. ABS Module Failure: The ABS control module (often integrated with the hydraulic control unit) can fail electronically or mechanically. This is a more serious and typically more expensive repair.
  3. Low Brake Fluid: While less likely to trigger ABS/TCS lights directly without a separate brake warning light, low fluid can affect pedal feel and overall braking.
  4. Wiring Issues: Damaged or corroded wiring to the wheel speed sensors or the ABS module can interrupt signals.
  5. Brake Pressure Sensor: A faulty brake pressure sensor within the ABS system can cause incorrect readings and trigger warnings.

What to do:

  1. Check Brake Fluid Level: Ensure your brake fluid reservoir is at the proper level.
  2. Scan for Codes: The most crucial first step is to get the vehicle scanned for diagnostic trouble codes (DTCs). A standard OBD-II scanner might not read ABS-specific C-codes, so a more advanced scanner or a visit to a shop is often necessary.
  3. Visual Inspection: If you're comfortable, visually inspect the wheel speed sensors (usually located near the wheel hub) and their wiring for any obvious damage or debris.

When to see a shop: Immediately. While your regular brakes might still function, the ABS and Traction Control systems are disabled, meaning you won't have anti-skid or traction assistance in emergency braking or slippery conditions. The spongy pedal also suggests a potential hydraulic issue that needs urgent attention to ensure full braking capability.
