Solution

1. Preparation

Gather tools including an OBD-II scanner, socket set, and a multimeter.
Ensure the vehicle is parked on a level surface and the ignition is off.

2. Retrieve and Clear Codes

Connect the OBD-II scanner to the vehicle’s diagnostic port.
Turn on the ignition without starting the engine.
Scan for DTCs, note any relevant codes, and clear them if needed.

3. Inspect and Clean Wheel Speed Sensors

Locate each wheel speed sensor; these are typically mounted on the wheel hub.
Disconnect the electrical connector for each sensor.
Clean the sensor and its mounting area using a wire brush and electrical cleaner.
Reconnect the sensors ensuring a secure fit.

4. Check ABS Module

Inspect the wiring harness connected to the ABS module for any signs of wear or disconnection.
Test the ABS module using a multimeter for proper voltage and continuity according to the manufacturer’s specifications.
Replace or repair any damaged components.

5. Test Battery and Electrical System

Measure the battery voltage with a multimeter; it should be between 12.4V to 12.7V.
If the voltage is low, charge or replace the battery as necessary.

6. Tire Inspection

Check all tires for proper inflation using a tire pressure gauge; inflate them to the recommended PSI.
Inspect tire tread for uneven wear and replace any tires that are excessively worn.
