Solution

1. Preparation

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

2. Retrieve Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn the ignition to the "ON" position without starting the engine.
Access the ABS system and record any error codes for reference.

3. Inspect Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Clean any dirt or debris from the sensor and mounting area.
Check the wiring harness for any frays or disconnections.
Reconnect any loose connections and secure the wiring.

4. Check Brake Fluid and Module

Inspect the brake fluid reservoir for proper fluid level.
If low, add OEM-approved brake fluid to the required level.
Examine the ABS module for any visible damage or leaks.
Ensure all electrical connections to the ABS module are secure.

5. Test ABS Pump and Relay

Locate the ABS pump and relay based on the vehicle’s service manual.
Using a multimeter, test the relay for continuity.
If faulty, replace the relay with a new one.
If the pump is suspected to be faulty, consult the service manual for replacement instructions.

6. Reset ABS System

Reconnect the battery and turn the ignition to "ON."
Use the OBD-II scanner to clear any stored ABS fault codes.
Start the vehicle and check if the ABS light remains off.
