Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.

2. Scan for Error Codes

Use an OBD-II scanner to retrieve any stored ABS-related error codes.
Document the codes for further analysis.

3. Inspect ABS Wheel Speed Sensors

Locate the wheel speed sensors at each wheel hub.
Clean any dirt or debris from the sensors and their mounting points.
Check for any damaged wiring or connectors and replace if necessary.

4. Check Brake Fluid Level

Remove the brake fluid reservoir cap.
Inspect the fluid level; if low, top it off with the manufacturer-recommended brake fluid.
Inspect for any leaks around the brake lines and connections.

5. Test ABS Pump and Relay

Locate the ABS pump and relay.
Use a multimeter to check for proper voltage at the pump when the ignition is turned on.
If the pump does not activate, replace the relay or pump as needed.

6. Inspect ABS Control Module

Check the wiring harness connected to the ABS control module for corrosion or disconnections.
If necessary, replace the ABS control module after verifying all other components are functioning correctly.
