Solution

1. Preparation

Gather tools and materials: OBD-II scanner, multimeter, socket set, torque wrench, and safety glasses.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to prevent electrical shorts.

2. Scan and Diagnose

Use the OBD-II scanner to read and document any fault codes related to the ABS and traction control systems.
Clear the codes and perform a road test to see if the codes return. If they do, note them for further analysis.

3. Inspect Wheel Speed Sensors

Remove the wheel to gain access to the wheel speed sensor.
Disconnect the wheel speed sensor electrical connector.
Use a multimeter to test the sensor’s resistance (should be within the manufacturer's specifications).
Clean or replace the sensor if damaged or if readings are out of spec.

4. Check ABS Fuse

Locate the fuse box and identify the ABS fuse using the diagram.
Remove the fuse and check for continuity using a multimeter. Replace if blown.

5. Examine ABS Control Module

Inspect the ABS control module for visible signs of damage, corrosion, or loose connections.
If necessary, re-seat connectors and clean any corrosion with an electronic cleaner.

6. Verify Brake Fluid Level

Remove the brake fluid reservoir cap and check the fluid level; top off with recommended fluid if low.
Inspect for any leaks in the brake system that may cause fluid loss.
