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. Check and Replace Wheel Speed Sensors

Sub-steps:
1. Locate the wheel speed sensors on each wheel hub.
2. Disconnect the wiring harness from the sensors.
3. Remove the sensor using a socket set (typically 10-12mm).
4. Inspect the sensor for debris and damage; replace if necessary.
5. Reinstall the new or cleaned sensor and reconnect the wiring harness.

3. Inspect and Refill Brake Fluid

Sub-steps:
1. Locate the brake fluid reservoir under the hood.
2. Check the fluid level; if low, add the appropriate DOT brake fluid.
3. Inspect for any leaks in brake lines or around the master cylinder.

4. Test and Repair ABS Module

Sub-steps:
1. Reconnect the battery.
2. Use a multimeter to test voltage at the ABS module.
3. If no voltage is present, trace the wiring back to the fuse box and check for blown fuses or damaged wiring.
4. Replace the ABS module if it fails the test.

5. Clear Error Codes and Test Drive

Sub-steps:
1. Use the OBD-II scanner to clear any error codes.
2. Take the vehicle for a test drive to ensure the traction control system operates correctly.
