Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, torque wrench, and cleaning supplies.
Ensure the vehicle is parked on a level surface and the engine is off before beginning work.

2. Clear DTCs

Connect the OBD-II scanner to the vehicle’s diagnostic port.
Follow the scanner's prompts to read and clear any codes related to traction control.
Disconnect the scanner after clearing codes.

3. Inspect and Clean Wheel Speed Sensors

Remove the wheel if necessary for better access to the wheel speed sensors.
Disconnect the sensor wiring harness.
Clean the sensor and mounting area with a suitable cleaner to remove any debris.
Reinstall the sensor and reconnect the wiring harness, ensuring a secure connection.

4. Test ABS Module

Use a multimeter to check the voltage at the ABS module connector.
Compare readings with manufacturer specifications. Repair or replace the module if readings are out of range.

5. Check Brake Fluid Levels

Open the brake fluid reservoir cap and inspect fluid levels.
If low, top off with manufacturer-recommended brake fluid.
Inspect for any signs of leaks in brake lines or around the master cylinder.

6. Adjust Wheel Alignment

Take the vehicle to a certified alignment shop to ensure proper wheel alignment.
Request a printout of the alignment specifications for reference.
