Solution

1. Preparation

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

2. Diagnose Wheel Speed Sensors

Tools Required: OBD-II scanner, multimeter
Remove the wheel covering the suspected sensor.
Disconnect the wheel speed sensor connector.
Use a multimeter to check the sensor's resistance (specifications depend on the specific sensor, typically 1000-3000 ohms).
If the resistance is outside this range, replace the wheel speed sensor.

3. Inspect ABS Module

Tools Required: Diagnostic scanner
Reconnect the battery and use the OBD-II scanner to check for ABS module fault codes.
If codes are present, follow the manufacturer's guidelines for troubleshooting and addressing the specific codes.
If the module is faulty, replace it with a compatible ABS module.

4. Check Wiring and Connectors

Visually inspect the wiring harness and connectors for any signs of damage or corrosion.
Clean any corroded connectors with electrical contact cleaner.
Repair or replace damaged wiring as necessary.

5. Test Traction Control Switch

Tools Required: Multimeter
Disconnect the traction control switch from the dashboard.
Use a multimeter to test for continuity. If the switch is faulty, replace it with a new one.
