Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface with the engine off.
Disconnect the battery to prevent electrical shorts.

2. Check and Replace Wheel Speed Sensors

Sub-steps:
1. Locate the wheel speed sensors at each wheel hub.
2. Remove the sensor electrical connector.
3. Unscrew and remove the wheel speed sensor from its mounting.
4. Inspect the sensor for damage; replace if necessary.
5. Reinstall the new or inspected sensor and reconnect the electrical connector.
6. Repeat for all wheel speed sensors if needed.

3. Inspect and Refill Brake Fluid

Sub-steps:
1. Locate the brake fluid reservoir under the hood.
2. Check the fluid level; if low, inspect for leaks in the brake lines or ABS module.
3. If leaks are found, repair the affected areas before proceeding.
4. If fluid is low but no leaks are detected, refill with the appropriate brake fluid (DOT 4 or as specified).
5. Reconnect the battery.

4. Reset Traction Control System

Sub-steps:
1. Use the OBD-II scanner to clear any fault codes.
2. Start the engine and check if the traction control light remains off.
3. Test drive the vehicle to ensure the traction control system is functioning properly.
