Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, basic hand tools.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the negative terminal of the battery for safety.

2. Check Brake Fluid Level

Locate the brake fluid reservoir under the hood.
If the fluid level is low, refill with the manufacturer-recommended brake fluid.
Reconnect the battery terminal.

3. Update Software

Power on the vehicle and navigate to the software update section in the main menu.
If an update is available, follow the prompts to download and install it.
Restart the vehicle after the update completes.

4. Inspect Wheel Speed Sensors

Remove the wheel covers or tires to access the wheel speed sensors.
Visually inspect the sensors for any damage or disconnection.
Use a multimeter to check the resistance of the sensors; if out of spec, replace them.

5. Check ABS Module

Use the OBD-II scanner to read any error codes related to the ABS module.
If codes indicate a failure, inspect the wiring and connections to the ABS module.
Clear any codes after repairs and test the system.

6. Test Traction Control System

Reconnect the battery terminal.
Start the vehicle and drive at low speeds to test the traction control functionality.
Monitor the dashboard for any recurring messages or warnings.
