Solution

1. Preparation

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

2. Scan and Clear Codes

Tools Required: OBD-II scanner
Connect the OBD-II scanner to the vehicle’s diagnostic port.
Turn the ignition to the "On" position without starting the engine.
Retrieve and note any ABS fault codes displayed.
Clear the codes and turn off the ignition.

3. Inspect ABS Components

Tools Required: Socket set, multimeter
Reconnect the battery.
Raise the vehicle using a jack and secure it with jack stands.
Inspect the wheel speed sensors at each wheel:
- Remove the sensor harness connector.
- Check for corrosion or dirt; clean if necessary.
- Use a multimeter to check resistance according to manufacturer specifications.
Inspect the wiring harness for any frays or damage.

4. Check Brake Fluid and System

Tools Required: Brake fluid tester
Open the brake fluid reservoir and check the fluid level.
If low, top off with the recommended brake fluid type.
Inspect for any leaks in the brake lines or around the ABS module.

5. Test ABS Module and Pump

Tools Required: Multimeter
Locate the ABS module and check for proper voltage and ground connections.
Test the ABS pump operation by activating it through the OBD-II scanner if possible.
Replace any faulty components identified during testing.

6. Reassemble and Test Drive

Reconnect all connectors and ensure everything is secured.
Lower the vehicle.
Reconnect the negative battery cable.
Start the engine and conduct a test drive to check for ABS light status and performance.
