Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the battery's negative terminal to prevent electrical shorts.
Ensure the vehicle is on a level surface and properly secured with jack stands if necessary.

2. Inspect and Replace Wheel Speed Sensors

Tools Required: Socket set, torque wrench, multimeter
Locate each wheel speed sensor on the front and rear wheels.
Disconnect the sensor connector and remove the sensor from its mount.
Use a multimeter to test for continuity. If faulty, replace the sensor.
Install the new sensor, ensuring it is securely fastened and reconnect the wiring harness.
Torque the sensor to manufacturer specifications.

3. Check and Replace Brake Fluid

Tools Required: Brake fluid, funnel, brake bleeder kit
Inspect the brake fluid reservoir for low fluid levels.
If low, top off with the appropriate type of brake fluid (consult owner’s manual).
Bleed the brake system to remove any air bubbles if necessary.

4. Inspect and Replace ABS Module

Tools Required: Socket set, diagnostic tool
If the ABS module is suspected to be faulty, disconnect the battery again.
Remove the ABS module by unscrewing the bolts that secure it.
Disconnect the electrical connectors from the module.
