Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety.

2. Scan for Error Codes

Use an OBD-II scanner to retrieve ABS-related error codes.
Record the codes for reference during the repair process.

3. Inspect ABS Components

ABS Fuse Check:
- Locate the fuse box and identify the ABS fuse.
- Remove the fuse and inspect it for continuity; replace if blown.
Wheel Speed Sensor Check:
- Lift the vehicle securely using jack stands.
- Locate the wheel speed sensors at each wheel hub.
- Check for dirt or debris; clean if necessary.
- Inspect wiring and connectors for damage; repair or replace as needed.

4. Test ABS Pump

Reconnect the battery terminal.
Turn the ignition to the "ON" position without starting the engine.
Activate the ABS system through a diagnostic tool to listen for operation of the ABS pump.

5. Brake Fluid Inspection

Check the brake fluid reservoir; ensure it is filled to the recommended level.
If low, top off with the appropriate brake fluid (DOT 3 or DOT 4 as specified in the owner’s manual).
Inspect for leaks in the brake lines, calipers, and around the ABS module.

6. Clear Error Codes

Use the OBD-II scanner to clear any error codes from the system.
Test drive the vehicle to ensure the ABS light does not reappear.
