Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the ignition is off.
Gather tools and parts required for the repair.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Replace Wheel Speed Sensors

Tools Required: Socket set, multimeter, wire brush
Remove the wheel corresponding to the faulty sensor.
Disconnect the wiring harness from the wheel speed sensor.
Remove the sensor using a socket and inspect for dirt or debris. Clean with a wire brush if necessary.
If the sensor is damaged, replace it with a new one. Torque the new sensor to manufacturer specifications (typically around 10-15 lb-ft).
Reconnect the wiring harness and reinstall the wheel.

3. Examine and Repair ABS Module

Tools Required: Torx socket set, multimeter
Locate the ABS module, usually found near the master cylinder.
Disconnect the ABS module wiring harness and inspect for corrosion or loose connections.
If corrosion is present, clean the terminals with an electrical contact cleaner.
Reconnect the wiring harness and ensure all connections are secure.
If the module is faulty, replace it following the manufacturer's service manual.

4. Check and Replace Brake Fluid

Tools Required: Brake bleeder kit, container
Remove the brake fluid reservoir cap.
Check the fluid level; if low, top off with the recommended brake fluid (DOT 3 or DOT 4).
If the fluid appears dirty or contaminated, replace it by bleeding the brake lines.
Use a brake bleeder kit to remove old fluid until new fluid appears at each brake caliper.
