Solution

1. Preparation

Gather all tools and parts required for the repair.
Make sure the vehicle is parked on a level surface and the ignition is off.
Disconnect the negative battery terminal to ensure safety.

2. Check and Replace Wheel Speed Sensors

Tools Required: Socket set, multimeter
Remove the wheel and tire for access to the wheel speed sensors.
Inspect each wheel speed sensor for damage or dirt buildup.
If faulty, disconnect the sensor connector and remove the sensor using the socket set.
Install the new wheel speed sensor, ensuring it is seated properly.
Reconnect the sensor connector and reinstall the wheel and tire.

3. Inspect and Replace ABS Module (if necessary)

Tools Required: Socket set, torque wrench
Locate the ABS module, typically near the master cylinder.
Disconnect the wiring harness from the ABS module.
Remove the mounting bolts using the socket set and carefully extract the module.
Install the new ABS module, ensuring proper alignment.
Torque the mounting bolts to the manufacturer's specifications.
Reconnect the wiring harness to the new ABS module.

4. Refill and Bleed Brake Fluid

Tools Required: Brake fluid, brake bleeder kit
Check the brake fluid reservoir level; refill with the appropriate type of brake fluid.
Use the brake bleeder kit to bleed air from the brake lines, starting from the furthest brake from the master cylinder.
Ensure that the brake pedal feels firm after bleeding.

5. Reconnect Battery and Clear Codes

Reconnect the negative battery terminal.
Use an OBD-II scanner to clear any stored ABS error codes.
Start the vehicle and check if the ABS light remains off.
