Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shorts.
Ensure the vehicle is on a flat surface and secured with wheel chocks.

2. Scan for Codes

Use the OBD-II scanner to read any fault codes.
Write down the codes for reference and clear them to see if they return after a test drive.

3. Inspect ABS Wheel Speed Sensors

Locate the ABS wheel speed sensors on each wheel.
Clean the sensors and their mounting area using an appropriate cleaner.
Check for any damaged wires or loose connections; repair or replace as needed.

4. Check Fuse and Wiring

Locate the ABS fuse in the fuse box and inspect it for continuity using a multimeter.
Replace the fuse if it is blown.
Visually inspect the wiring harness leading to the ABS module for any signs of wear or damage.

5. Brake Fluid Check

Open the brake fluid reservoir and check the fluid level; top off with the recommended brake fluid if low.
Inspect the fluid for contamination; replace if necessary.

6. Test Drive

Reconnect the battery terminal and start the vehicle.
Take the vehicle for a short test drive to check if the ABS and traction control lights are still illuminated.
