Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Clean Wheel Speed Sensors

Tools Required: Socket set, cleaning solution, and a soft brush.
Locate the wheel speed sensors at each wheel hub.
Remove the mounting bolts using the socket set.
Carefully detach the sensor from its position.
Clean the sensor and its connector with the cleaning solution and soft brush.
Reinstall the sensors securely and torque bolts to manufacturer specifications.

3. Check Brake Fluid Level

Tools Required: Clean rag and funnel.
Locate the brake fluid reservoir under the hood.
Check the fluid level against the minimum and maximum marks.
If low, add the appropriate brake fluid (DOT 4) to the reservoir.

4. Inspect ABS Module and Wiring

Tools Required: Multimeter and visual inspection tools.
Locate the ABS module, usually found near the master cylinder.
Inspect wiring harness for frays or disconnections.
Use a multimeter to test the module for proper voltage and ground.

5. Test Traction Control Switch

Tools Required: Multimeter.
Locate the traction control switch on the dashboard.
Disconnect the switch and use the multimeter to check for continuity.
Replace the switch if it shows no continuity when engaged.
