68210119AB | Genuine Mopar® ABS AntiLock Brake Module Dodge/Chrysler

• Prevent Wheel Lock-Up

  • During hard braking or slippery conditions, the ABS module modulates brake pressure to prevent the wheels from locking.

  • Locked wheels reduce traction and steering control, so ABS helps maintain directional control.

• Maintain Steering Control

  • By preventing wheel lock-up, the ABS allows the driver to continue steering while braking, which can help avoid obstacles.

• Optimize Braking Efficiency

  • The module rapidly pulses the brakes (often multiple times per second) to maximize stopping power without losing traction.

• Integrate With Other Vehicle Safety Systems

  • ABS modules often work with Electronic Stability Control (ESC), Traction Control System (TCS), and Brake Assist, providing coordinated control during emergencies.

• Monitor Wheel Speed and Brake Performance

  • The ABS module receives data from wheel speed sensors to detect traction loss and adjust brake pressure accordingly.

1. ABS Warning Light On

• The ABS warning light on your dashboard stays on or flashes while driving.

• This is the most obvious sign the module or system has a problem.

2. Brake Pedal Issues

• Brake pedal may feel spongy, stiff, or unresponsive.

• ABS might engage unnecessarily or fail to engage during hard braking.

3. Wheel Locking During Braking

• If wheels lock up under hard braking, the ABS is not modulating brake pressure correctly.

• Can be especially noticeable on slippery roads.

4. Unusual Brake Behavior

• Brakes pulsating when not needed or not pulsating during emergencies.

• Braking may feel uneven or jerky.

5. Inconsistent ABS Function

• Traction control or stability control warning lights may come on (since these systems often rely on the ABS module).

• ABS might work intermittently — sometimes it works, sometimes it doesn’t.

6. Failed Diagnostic Test

• Using a scan tool can show ABS module errors or communication failures with wheel speed sensors.
