Solution

1. Preparation

Gather necessary tools and parts. Ensure the vehicle is parked on a flat surface and the engine is off.
Tools Required: OBD-II scanner, socket set, multimeter, brake fluid, cleaning supplies.

2. Retrieve and Interpret Codes

Connect the OBD-II scanner to the vehicle’s diagnostic port.
Turn the ignition to the "On" position without starting the engine.
Retrieve ABS-related codes. Take note of any codes displayed for further investigation.

3. Inspect Wheel Speed Sensors

Raise the vehicle and securely support it with jack stands.
Locate the wheel speed sensors on each wheel hub.
Disconnect the sensor connector and inspect the wire harness for any damage.
Use a multimeter to check the sensor resistance (typically between 1,000 and 2,000 ohms). Replace if out of range.

4. Check Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
Ensure the brake fluid is at the recommended level; if low, top it up with the appropriate brake fluid type as specified in the owner’s manual.
Inspect for leaks in the brake lines and around the master cylinder.

5. Inspect ABS Module and Wiring

Visually check the ABS module for any signs of damage or corrosion.
Inspect the wiring harness connected to the ABS module for frays or disconnections.
Clean any corrosion present on the connectors using electrical contact cleaner.

6. Clear Codes and Test Drive

Use the OBD-II scanner to clear any stored ABS codes.
Start the vehicle and perform a test drive to check if the ABS light remains off.
