Solution

1. Preparation

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

2. Scan for Codes

Connect an OBD-II scanner to the vehicle's diagnostic port.
Turn on the ignition without starting the engine.
Retrieve and note any ABS-related error codes for reference.

3. Inspect Wheel Speed Sensors

Locate each wheel speed sensor (usually near the brake rotor).
Clean any dirt or debris from the sensor and mounting area.
Check the sensor wiring for frays or disconnections.

4. Check ABS Fuse

Locate the fuse box, typically under the dash or hood.
Find the ABS fuse and remove it.
Use a multimeter to check for continuity; replace if blown.

5. Inspect Brake Fluid

Open the hood and locate the brake fluid reservoir.
Check the fluid level; if low, add the manufacturer-recommended brake fluid.
If the fluid appears dirty or contaminated, perform a brake fluid flush.

6. Test ABS Module

If no issues are found with the sensors or fluid, test the ABS module.
Use a multimeter to check the power and ground connections to the module.
If there are electrical issues, repair or replace the wiring as necessary.

7. Clear Codes and Test Drive

After repairs, clear the ABS codes using the OBD-II scanner.
Take the vehicle for a test drive to verify proper operation of the ABS system.
