Solution

1. Preparation

Gather tools and parts before starting the repair.
Ensure the vehicle is parked on a level surface and turn off the ignition.
Disconnect the battery to avoid electrical shorts during the repair.

2. Inspect Wheel Speed Sensors

Remove the wheel corresponding to the sensor you are inspecting.
Clean the wheel speed sensor area with a suitable cleaner to remove any debris.
Check the wiring harness for cracks, frays, or loose connections.
Reconnect the sensor and ensure it is securely fastened.

3. Check Traction Control Module

Locate the traction control module, typically found under the dashboard or near the brake master cylinder.
Inspect for any visible damage or corrosion on the module and its connectors.
Use a multimeter to test the voltage and continuity of the wiring to the module.
Replace the module if it shows faults or if the connections are compromised.

4. Inspect ABS System

Check the ABS pump and control module for proper operation and electrical connections.
Use the OBD-II scanner to perform an ABS system test if available.
Replace any defective components identified during testing.

5. Verify Tire Condition and Pressure

Check tire pressure using a tire pressure gauge, ensuring they match the manufacturer’s specifications.
Inspect tires for uneven wear, damage, or insufficient tread depth.
Replace any damaged tires and ensure all tires are inflated properly.
