Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, brake fluid, cleaning supplies.
Safety Warnings: Disconnect the battery before working on electrical systems to prevent short circuits.

2. Address Faulty Wheel Speed Sensors

Raise the vehicle using a jack and secure it on jack stands.
Locate each wheel speed sensor at the wheel hub.
Disconnect the electrical connector from the sensor.
Remove the sensor using the appropriate socket.
Clean the sensor and its mounting area of any debris or dirt.
If the sensor is damaged, replace it with a new one and reconnect the electrical connector.

3. Inspect and Repair ABS Module

Locate the ABS module under the hood. Refer to the owner’s manual for precise location.
Check the wiring harness connected to the ABS module for any signs of wear or damage.
If damaged, repair or replace the wiring as necessary.
Ensure all connections are secure and free of corrosion.

4. Brake Fluid Check and Replacement

Open the brake fluid reservoir cap located on the master cylinder.
Check the fluid level; if low, top it off with the manufacturer-recommended brake fluid.
If the fluid is contaminated (dark or cloudy), perform a brake fluid flush:
- Attach a brake bleeder kit to the brake caliper.
- Pump the brakes until clean fluid flows through the line.
- Repeat for each wheel until the fluid runs clear.

5. Clear Error Codes

Reconnect the battery after all repairs.
Use the OBD-II scanner to clear any stored ABS error codes.
Turn the ignition off and then restart the vehicle to check if the ABS light remains off.
