Solution

1. Preparation

Gather tools and equipment, ensuring the vehicle is parked on a flat surface.
Disconnect the battery to ensure safety while working on the ABS system.

2. Inspect ABS Sensors

Tools Required: Socket set, multimeter
Remove the wheel to access the ABS sensor.
Disconnect the ABS sensor connector.
Use a multimeter to test the sensor for continuity. If the reading is outside manufacturer specifications, replace the sensor.
Clean any debris or rust from the sensor mounting area and reinstall the sensor.

3. Check ABS Control Module

Tools Required: OBD-II scanner, socket set
Locate the ABS control module, usually found near the master cylinder or under the vehicle.
Inspect the module for any visible signs of damage or corrosion.
Using an OBD-II scanner, clear any fault codes and re-check for codes after a test drive. If codes return, consider replacing the ABS module.

4. Inspect Wiring and Connectors

Tools Required: Visual inspection tools
Trace the wiring from the ABS sensors back to the ABS module.
Look for frayed wires, corrosion, or loose connections.
Repair or replace any damaged wiring or connectors as needed.

5. Reassemble and Test

Reconnect the battery.
Reinstall the wheel and lower the vehicle.
Test drive the vehicle to ensure proper function of the ABS system and check if the ABS light remains off.
