Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.

2. Retrieve Fault Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn the ignition to the "ON" position without starting the engine.
Navigate the scanner to retrieve ABS-related trouble codes and note any codes displayed.

3. Inspect and Replace Faulty Components

A. Fuse Inspection

Locate the fuse box and find the ABS fuse.
Use a multimeter to check for continuity in the fuse.
Replace the fuse if it is blown (use a fuse of the same amperage).

B. Brake Fluid Check

Open the master cylinder reservoir cap.
Check the fluid level; top up with the manufacturer-recommended brake fluid if low.
If the fluid is contaminated, perform a brake fluid flush.

C. Wheel Speed Sensor Inspection

Raise the vehicle and remove the wheel to access the wheel speed sensor.
Clean the sensor and its mounting area with brake cleaner.
Check the wiring for any signs of wear or breaks.
Replace the sensor if damaged.

4. Test ABS Module

Using a multimeter, check the voltage at the ABS module.
If no voltage is present, trace back to the power source and repair any broken wiring.
If the module is defective, replace it according to manufacturer specifications.
