Solution

1. Preparation

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

2. Scan for Error Codes

Use an OBD-II scanner to check for any stored codes.
Note any codes related to the traction control system and write them down for further analysis.

3. Inspect Wheel Speed Sensors

Remove the wheel covers or wheel assemblies if necessary.
Locate the wheel speed sensors on each wheel hub.
Check for physical damage, dirt, or debris on the sensors.
Clean the sensors if dirty and reconnect any loose wires.

4. Check Brake Fluid Level

Locate the brake fluid reservoir.
Inspect the fluid level; add recommended brake fluid (DOT 3 or DOT 4) if low.
Look for any signs of leaks around brake lines and connections.

5. Examine ABS Module

Locate the ABS module, typically near the master cylinder.
Check for any loose or damaged electrical connections.
Perform a functional test if possible, following the specific procedure for your model.

6. Test Traction Control Switch

Locate the traction control switch on the dashboard.
Ensure it is functioning correctly by pressing it to toggle the traction control on and off.
Replace if faulty.
