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.
