22752690 | Genuine GM® ABS Module For GMC Terrain, Chevrolet Equinox

An ABS Module (Anti-lock Braking System Module) 22752690 is the electronic control unit that manages the ABS system in a vehicle. It works together with wheel speed sensors and the ABS hydraulic unit to prevent wheel lock-up during braking.

General Specifications

Fitment

Fitment can vary by engine build and options. Match the part number on the part you are replacing, or contact us with your vehicle details before ordering.

Purpose & Function

1. Monitors Wheel Speed

Receives signals from wheel speed sensors to detect when a wheel is about to lock up.

2. Controls Brake Pressure

Sends commands to the ABS hydraulic pump and valves to rapidly:

• Increase

• Hold

• Release
  brake pressure to prevent skidding.

3. Improves Steering Control During Braking

By preventing wheel lock-up, it allows the driver to steer while braking hard.

4. Enhances Stability and Safety

Works with other systems such as:

• Traction Control

• Electronic Stability Control (ESC)

• Brake Assist

5. Stores Diagnostic Trouble Codes

If the ABS system fails, the module:

• Turns on the ABS warning light

• Stores fault codes for technicians

Signs of a Bad ABS Module

1. ABS Warning Light or Brake Light Turns On

• The ABS light, Brake light, or both may illuminate

• Often the first and most obvious symptom

• The module stores fault codes that point to ABS system issues

2. Anti-Lock Brakes Stop Working

• ABS will be disabled, and the vehicle may revert to normal braking

• During hard braking, wheels may lock up, causing skidding

3. Traction Control or Stability Control Light Comes On

• Since ABS, Traction Control, and ESC share sensors and circuits, module failure can trigger:

  • TCS light

  • ESC/ESP light

4. Brake Pedal Feels Unusual

• Pedal may feel:

  • Harder than normal

  • Softer/spongy

  • Pulsate at the wrong times

5. Speedometer Malfunctions (on certain vehicles)

• Some ABS modules share signals with the speedometer

• Speed reading may be wrong or drop to zero intermittently

6. ABS Pump Running Constantly

• A damaged module may send incorrect commands causing the pump to:

  • Run continuously

  • Run even when the car is off
    This can drain the battery.

7. Poor Braking Performance

• Increased stopping distance on slippery roads

• Vehicle may skid or slide during emergency braking

8. Intermittent Braking Issues

• ABS may activate randomly when it shouldn’t

• Or fail to activate when it should
