Solution

1. Preparation

Gather the necessary tools and parts.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Scan for Error Codes

Use the OBD-II scanner to retrieve any ABS-related codes.
Record the codes for further analysis and troubleshooting.

3. Inspect Wheel Speed Sensors

Remove the wheel (if necessary) to access the sensors.
Clean any debris from the sensor area.
Check the sensor’s electrical connector for secure fit and corrosion.
Use a multimeter to test the sensor resistance according to manufacturer's specifications.

4. Check ABS Module and Wiring

Visually inspect the ABS module for any signs of damage.
Trace the wiring harness for any frays, breaks, or corrosion.
Repair or replace any damaged wiring or connectors.

5. Test and Replace Brake Fluid

Check the brake fluid level in the master cylinder reservoir.
If fluid is low, fill it to the recommended level with the correct type of brake fluid (usually DOT 3 or 4).
If the brake fluid is contaminated or discolored, perform a brake fluid flush.

6. Clear Codes and Test Drive

Reconnect the negative battery terminal.
Clear the ABS codes using the OBD-II scanner.
Test drive the vehicle to ensure the ABS light does not reappear and the ABS functions properly.
