Solution

1. Preparation

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

2. Inspect Wheel Speed Sensors

Tools Required: Socket set, multimeter
Remove the wheel cover and tire to access the wheel speed sensor.
Disconnect the sensor connector and inspect for corrosion or damage.
Use a multimeter to test the sensor's resistance; compare with specifications in the service manual.
If faulty, replace the wheel speed sensor.

3. Check Traction Control Switch

Tools Required: Screwdriver set
Locate the traction control switch on the dashboard.
Remove the switch from its housing and inspect the wiring for continuity.
If defective, replace the switch with a new one.

4. Examine ABS Control Module

Tools Required: OBD-II scanner, socket set
Use the OBD-II scanner to check for ABS module fault codes.
If codes indicate issues, locate the ABS module in the engine bay and check connections and wiring.
If necessary, replace the ABS module per service manual instructions.

5. Inspect Brake Fluid and System

Tools Required: Brake fluid tester, wrench set
Check the brake fluid level in the reservoir; replenish if low with the recommended type.
Inspect brake lines and fittings for leaks or damage.
If leaks are found, replace affected components and bleed the brake system.
