Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the negative battery terminal to prevent electrical shock.

2. Scan for Error Codes

Use an OBD-II scanner to connect to the vehicle’s diagnostic port.
Record any ABS-related codes found for further analysis.
Clear the codes and check if the ABS light returns after a short test drive.

3. Inspect ABS Sensors

Lift the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the ABS sensor.
Inspect the sensor for dirt or damage; clean or replace if necessary.
Reconnect any loose wiring and ensure proper fitment of the sensor.

4. Check Brake Fluid and System

Remove the brake fluid reservoir cap and check the fluid level.
If low, top off with the manufacturer-recommended brake fluid.
Inspect for any leaks in brake lines and connections.
Replace any damaged brake lines as needed.

5. Test ABS Module

Reconnect the battery terminal.
Use a multimeter to check the voltage and continuity at the ABS module.
If voltage readings are outside specifications, replace the ABS module.

6. Reassemble and Test

Reinstall the wheels and lower the vehicle.
Test drive the vehicle to check if the ABS light remains off.
Monitor the braking performance and look for any abnormal behavior.
