Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is turned off.
Disconnect the battery to prevent any electrical shorts during repairs.

2. Inspect and Replace Wheel Speed Sensors

Tools Required: Socket set, multimeter, torque wrench.
Locate the wheel speed sensors at each wheel hub.
Remove the sensor bolts and gently pull the sensor from its housing.
Use a multimeter to check the sensor's resistance. Replace if outside specifications.
Reinstall new or cleaned sensors, ensuring they are secure. Torque the bolts to manufacturer specifications.

3. Check and Replace ABS Fuse

Locate the fuse box; refer to the owner’s manual for the specific location of the ABS fuse.
Remove the ABS fuse and check for continuity using a multimeter.
If the fuse is blown, replace it with one of the same amperage rating.
Reinstall the fuse and ensure it is seated properly.

4. Inspect ABS Module and Wiring

Visually inspect the ABS module for any physical damage or corrosion.
Check the wiring harness connected to the ABS module for frayed wires or loose connections.
If damage is found, repair or replace the affected wiring or connectors.

5. Refill and Bleed Brake Fluid

Tools Required: Brake fluid, brake bleeder kit.
Check the brake fluid reservoir and top off with the recommended brake fluid type.
Bleed the brake system to remove any air bubbles, which can affect ABS functionality.
