Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to avoid electrical shorts.

2. Inspect and Clean Wheel Speed Sensors

Locate the wheel speed sensors on each wheel hub.
Remove any debris or dirt from the sensors and their connectors using a clean rag.
If sensors are damaged or malfunctioning, proceed to replace them.

3. Check and Repair Wiring Harness

Inspect the wiring harness connected to the ABS control module and wheel speed sensors for fraying or breaks.
Use a multimeter to test for continuity in the wires.
Repair or replace any damaged wiring as necessary.

4. Check ABS Control Module

Reconnect the battery and use an OBD-II scanner to check for ABS control module codes.
If codes indicate a malfunction, consider replacing the ABS control module.
Follow the manufacturer's instructions for removal and installation, ensuring proper torque specifications are met.

5. Brake Fluid Inspection and Replacement

Check the brake fluid reservoir for proper fluid level and clarity.
If the fluid is low or contaminated, drain the old fluid and replace it with the manufacturer's recommended brake fluid.
Bleed the brake system to remove any air trapped in the lines.
