Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, basic hand tools, brake fluid.
Safety Warning: Disconnect the battery before working on electrical systems.

2. Addressing Error Codes

Retrieve error codes from the OBD-II scanner.
Research the codes to determine the root cause of the ABS light.
Clear the codes and see if they return after a test drive.

3. Inspect and Replace Wheel Speed Sensors

Lift the vehicle and remove the wheel to access the wheel speed sensor.
Disconnect the sensor connector and use a multimeter to test for proper voltage.
If faulty, remove the sensor by unscrewing it from its mount and replace it with a new one.
Reconnect the sensor and wheel, then lower the vehicle.

4. Check and Refill Brake Fluid

Open the brake fluid reservoir and check fluid levels.
If low, top off with the manufacturer-recommended brake fluid.
Inspect for any leaks in the brake lines or connections.

5. Inspect and Replace ABS Module (if necessary)

Disconnect the battery and remove any covers to access the ABS module.
Inspect wiring and connections for damage.
If the module is defective, remove it and install a new ABS module, following the manufacturer’s specifications for torque settings.
