Solution

1. Preparation

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

2. Scan for Error Codes

Use the OBD-II scanner to retrieve any stored error codes related to the ABS.
Document the codes for further analysis.

3. Inspect Wheel Speed Sensors

Remove the wheel to access the wheel speed sensor.
Clean the sensor and its connector with electrical contact cleaner.
Check the wiring for any signs of fraying or breaks.
Reinstall the wheel.

4. Check ABS Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Remove the ABS fuse and inspect it for continuity using a multimeter.
Replace with a new fuse if blown.

5. Examine ABS Control Module

Locate the ABS control module, usually near the master cylinder.
Inspect for corrosion on connectors and wiring.
If necessary, clean corrosion and ensure all connections are secure.
