Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Inspect and Clean Wheel Speed Sensors

Sub-steps:
- Locate each wheel speed sensor, which is typically found near the brake rotor.
- Remove any debris or dirt from the sensor area using a soft cloth.
- If the sensor is damaged or malfunctioning, remove it using a socket set and replace it with a new one.
Tools Required: Socket set, soft cloth.

3. Check Brake Fluid Level

Sub-steps:
- Locate the brake fluid reservoir under the hood.
- Inspect the fluid level; if low, top it off with the recommended brake fluid (DOT 3 or DOT 4).
- Check for any leaks in the brake lines or calipers and repair as necessary.
Tools Required: Funnel for adding brake fluid.
Safety Warning: Ensure the vehicle is on a flat surface and the engine is off before checking the fluid.

4. Inspect ABS Module

Sub-steps:
- Locate the ABS module, which is typically mounted on or near the master cylinder.
- Check for any visible damage, loose connections, or corrosion on the connector pins.
- If necessary, clean the connectors with electrical contact cleaner and reconnect.
Tools Required: Electrical contact cleaner, socket set for potential disassembly.

5. Reconnect Battery and Test

Sub-steps:
- Reconnect the negative battery terminal.
- Start the engine and check if the traction control light remains illuminated.
- Perform a test drive to ensure the traction control system functions properly.
Safety Warning: Make sure no tools are left in the engine bay before reconnecting the battery.
