Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect ABS Sensors

Locate each ABS wheel sensor.
Remove any debris or dirt from the sensor area.
Disconnect the sensor electrical connector and inspect for corrosion.
If any sensor is damaged, replace it with a new one.

3. Check ABS Module and Wiring

Locate the ABS control module, typically near the master cylinder.
Inspect wiring harness for fraying or disconnection.
Use a multimeter to check for proper voltage and ground at the module connector.
If necessary, replace the ABS control module.

4. Brake Fluid Check and Replacement

Open the brake fluid reservoir cap.
Check the fluid level; if low, top off with manufacturer-recommended fluid (e.g., DOT 3 or DOT 4).
If fluid is contaminated, perform a complete brake fluid flush.

5. Reconnect Battery and Clear Codes

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