Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery cable to prevent electrical shorts.

2. Inspect and Clean Wheel Speed Sensors

Sub-steps:
- Remove the wheel on the affected side using a socket set.
- Locate the wheel speed sensor and disconnect the electrical connector.
- Remove the sensor from its mounting.
- Clean the sensor tip and surrounding area with brake cleaner to remove any debris.
- Reinstall the sensor and reconnect the electrical connector.

3. Check and Replace Brake Fluid

Sub-steps:
- Locate the brake fluid reservoir and check the fluid level.
- If low, top off with the recommended brake fluid (usually DOT 3 or DOT 4).
- If the fluid is dirty or contaminated, perform a brake fluid flush.

4. Inspect the ABS System

Sub-steps:
- Using an OBD-II scanner, check for ABS-related codes.
- If codes are present, further diagnose the ABS module and pump.
- Clear any error codes and test drive the vehicle to see if the traction control light remains off.

5. Check Wiring and Connectors

Sub-steps:
- Visually inspect the wiring harnesses related to the traction control and ABS systems.
- Look for signs of fraying, corrosion, or loose connections.
- Repair or replace any damaged wiring or connectors.
