Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and set the parking brake.
Disconnect the negative battery terminal to prevent any electrical shorts.

2. Inspect ABS Sensors

Locate each wheel speed sensor, typically mounted near the brake caliper.
Use a socket set to remove any mounting bolts.
Carefully clean the sensor area with a damp cloth.
Reinstall the sensors and ensure they are securely fastened.

3. Check Wiring and Connectors

Examine the wiring harness connected to each ABS sensor for damage or wear.
Repair any frayed wires with electrical tape or replace the damaged harness if necessary.
Ensure all connectors are clean and securely connected.

4. Brake Fluid Inspection

Open the hood and locate the brake fluid reservoir.
Check the fluid level; if low, add manufacturer-recommended brake fluid (DOT 3 or DOT 4).
If the fluid appears dark or contaminated, perform a brake fluid flush.

5. Reset ABS Light

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any stored ABS error codes.
Start the vehicle and check if the ABS light remains off.
