Solution

1. Preparation

Gather the necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Inspect Wheel Speed Sensors

Tools Required: Socket set, multimeter
Remove the wheel corresponding to the affected sensor.
Disconnect the wheel speed sensor connector.
Use a multimeter to check the resistance of the sensor; it should typically be within 1,000 to 2,000 ohms.
If the resistance is out of specification, replace the wheel speed sensor.

3. Check Brake Fluid Level

Tools Required: Clean rag
Locate the brake fluid reservoir under the hood.
Check the fluid level; if it is below the minimum mark, fill it with the appropriate brake fluid (DOT 3 or DOT 4 as specified in the owner's manual).
Clean any spilled fluid to avoid damage to vehicle components.

4. Inspect ABS Module

Tools Required: Socket set
Locate the ABS module, usually near the master cylinder.
Check for any visible signs of damage or leaks.
If any faults are detected, it may be necessary to replace the ABS module.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the vehicle and check if the traction control light is still illuminated.
Perform a test drive to see if the issue persists.
