Mopar® ABS System FAQs

How Does A Mopar® ABS System Work?

The anti-lock braking system (ABS) prevents the wheels on your Jeep Wrangler, Dodge Charger, or Chrysler Pacifica vehicle from locking up when you brake. This helps the tires maintain contact with the road surface, giving you more control over your vehicle. Sensors on each wheel detect when the wheel stops moving and begins to skid. The system reacts by releasing and then reapplying (or "pumping") the brakes rapidly to stop the skidding and maintain command.

What Are The Parts of A Mopar® ABS System?

There are four major components of the typical anti-lock braking system:

1. The speed sensors monitor how quickly the wheels are rotating.
2. Valves in the brake line allow, block, or release brake pressure.
3. The pump delivers that pressure to the calipers in the form of a hydraulic fluid.
4. The electronic control unit (ECU) acts as the brains of the system. It interprets data from the sensors to determine when to pump the brakes or not.

How Do You Spot ABS System Problems?

Even the best ABS system parts can go bad over time, though. Possible causes include a blown fuse, a sensor that's either damaged or covered in muck, a broken wire, or an ECU that's stopped working. Signs of trouble include:

• The ABS warning light stays on after you've started your vehicle
• Your brake pedal doesn't respond
• Your brakes lock up
• You need to press harder on the brake pedal
• Your speedometer fails
