Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Replace Wheel Speed Sensors

Locate the wheel speed sensors on each wheel hub.
Disconnect the wiring harness from the sensor.
Remove the sensor using a socket set (typically a 10mm).
Inspect the sensor for damage or dirt; clean if necessary.
Install a new wheel speed sensor if damaged or faulty:
- Position the new sensor into the hub.
- Tighten to the manufacturer's specified torque (usually around 10-12 ft-lbs).
Reconnect the wiring harness securely.

3. Check ABS Module and Wiring

Locate the ABS module under the hood.
Inspect all wiring harnesses for corrosion, fraying, or loose connections.
Clean any corroded connectors with electrical contact cleaner.
Reconnect any loose connections and ensure a secure fit.

4. Brake Fluid Inspection and Replacement

Check the brake fluid reservoir for proper fluid level.
If low, top off with the recommended brake fluid type (usually DOT 3 or DOT 4).
Inspect the fluid's condition; if contaminated, perform a brake fluid flush:
- Attach a brake bleeder kit to the brake caliper.
- Open the bleeder valve and allow old fluid to drain into a container.
- Continuously add new fluid to the reservoir until clear fluid flows from the bleeder.
- Close the bleeder valve and repeat for all four wheels.
