Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, brake fluid, cleaning solution.
Ensure the vehicle is parked on a flat surface and the ignition is turned off before starting work.

2. Address ABS Sensor Issues

Lift the vehicle using a jack and secure it with jack stands.
Remove the wheel corresponding to the ABS warning light.
Disconnect the ABS sensor connector at the wheel hub.
Inspect the sensor for dirt or damage; clean or replace as necessary.
Reconnect the sensor and wheel, ensuring all components are secure.

3. Brake Fluid Inspection

Locate the brake fluid reservoir under the hood.
Check the fluid level; if low, top it off with the recommended brake fluid type.
Inspect the fluid for contamination or discoloration. If contaminated, perform a brake fluid flush.

4. Testing ABS Module and Pump

Use a multimeter to check the power supply and ground to the ABS module.
If there is no power, trace the wiring back to the fuse box to check for blown fuses or broken wires.
If power is present, activate the ABS pump using the OBD-II scanner and listen for operation.

5. Reassemble and Reset the System

After repairs, reattach any components removed during the process.
Use the OBD-II scanner to clear any error codes and reset the ABS light.
Lower the vehicle and perform a test drive to ensure the ABS system is functioning correctly.
