Solution

1. Preparation

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

2. Scan for Error Codes

Use an OBD-II scanner to retrieve and document any stored error codes related to traction control.
Clear the codes after recording.

3. Inspect Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Disconnect the electrical connectors from the sensors.
Clean the sensor areas and check for any physical damage or debris.
Reconnect the sensors and ensure they are secure.

4. Check Brake Fluid Level

Open the hood and locate the master cylinder reservoir.
Check the brake fluid level; it should be within the recommended range.
If low, top off with the appropriate brake fluid type (typically DOT 3 or DOT 4).
Inspect for any leaks in the brake lines or around the reservoir.

5. Verify ABS Module Functionality

Check the ABS module connections and wiring for any signs of damage.
Perform an ABS self-diagnosis if applicable, following the manufacturer’s instructions.
If the ABS module is faulty, replace it with a new unit.

6. Reconnect Battery

After all checks and repairs, reconnect the battery terminal.
Ensure all connections are tight and secure.
