Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety during repairs.

2. Wheel Speed Sensor Inspection

Tools Required: Socket set, multimeter, cleaning brush
Remove the wheel for better access to the wheel speed sensor.
Disconnect the wheel speed sensor connector.
Use a multimeter to check resistance across the sensor terminals; it should be within manufacturer specifications (usually 1-2 kΩ).
If the sensor is faulty, clean it or replace it if necessary.

3. ABS Module Check

Tools Required: OBD-II scanner
Reconnect the battery and use the OBD-II scanner to check for ABS/traction control-related error codes.
If codes are present, note them down. Clear the codes and perform a test drive to see if they return.
If the ABS module is defective, it may need to be replaced or reprogrammed.

4. Wiring and Connector Inspection

Visually inspect the wiring harness leading to the ABS module and wheel speed sensors.
Look for any signs of wear, fraying, or corrosion.
Repair or replace any damaged wiring or connectors.

5. Brake Fluid Verification

Tools Required: Brake fluid tester
Check the brake fluid level in the reservoir; it should be between the MIN and MAX marks.
If the fluid is low, top it off with the recommended brake fluid type (usually DOT 4).
If the fluid is dirty or contaminated, perform a brake fluid flush.
