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 prevent electrical shorts.

2. Inspect Wheel Speed Sensors

Tools Required: Socket set, multimeter, cleaning brush.
Remove the wheel and tire from each corner of the vehicle.
Locate the wheel speed sensors on each wheel hub.
Clean any debris or dirt from the sensors and connectors.
Use a multimeter to check the resistance of each sensor, ensuring they meet specifications (typically around 1,000 to 1,500 ohms).
Replace any faulty sensors with new ones.

3. Check ABS Module

Tools Required: OBD-II scanner, socket set.
Reconnect the battery and turn the ignition to the "ON" position without starting the engine.
Use the OBD-II scanner to check for ABS module fault codes.
If faults are detected, repair or replace the ABS module as necessary.

4. Inspect Traction Control Switch

Tools Required: Screwdriver set.
Locate the traction control switch on the dashboard.
Remove the switch and inspect for any visible damage or corrosion.
Use a multimeter to check for continuity in the switch.
Replace the switch if it fails the test.

5. Brake Fluid and System Check

Tools Required: Brake fluid tester, fluid catch container.
Check the brake fluid level in the reservoir; top off if low with the recommended fluid type (DOT 3 or DOT 4).
Inspect brake lines and fittings for leaks.
Bleed the brake system if air is present.
