Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery for safety.

2. Retrieve and Address Trouble Codes

Use the OBD-II scanner to retrieve ABS trouble codes.
Note the codes and refer to the service manual for specific troubleshooting related to those codes.

3. Inspect and Replace Components

ABS Fuse Inspection:
- Locate the fuse box and check the ABS fuse.
- If blown, replace it with a fuse of the same amperage.
Wheel Speed Sensor Check:
- Raise the vehicle and remove the wheels to access the wheel speed sensors.
- Inspect for physical damage or disconnections; clean or replace as necessary.
ABS Control Module Inspection:
- Locate the ABS control module and check for corrosion or loose connectors.
- If faulty, replace the module according to manufacturer specifications.

4. Brake Fluid Check and System Bleeding

Check the brake fluid reservoir for proper fluid level; top off with manufacturer-recommended brake fluid if low.
If any leaks are detected, repair the source of the leak and bleed the brake system to remove air.

5. Reconnect Battery and Test Drive

Reconnect the battery and clear any stored trouble codes using the scanner.
Perform a test drive to verify that the ABS light does not illuminate during operation.
