Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, jack and jack stands, wheel chocks.
Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Inspect Wheel Speed Sensors

Sub-steps:
1. Raise the vehicle using a jack and secure with jack stands.
2. Locate the wheel speed sensors at each wheel hub.
3. Visually inspect the sensors for damage, corrosion, or loose connections.
4. Use a multimeter to test the sensors for proper resistance (typically 1,000-2,000 ohms).
5. If faulty, replace the wheel speed sensor.

3. Check Brake Fluid and System

Sub-steps:
1. Locate the brake fluid reservoir and check the fluid level.
2. Inspect for any leaks in the brake lines, calipers, or master cylinder.
3. If necessary, bleed the brake system to remove air and ensure proper fluid levels.
4. Refill the brake fluid reservoir with the manufacturer-recommended fluid.

4. ABS Module Inspection

Sub-steps:
1. Locate the ABS module in the engine compartment.
2. Check for any loose or damaged wiring leading to the module.
3. Use an OBD-II scanner to test for ABS-related error codes.
4. If the module is faulty, replace it following the manufacturer's service manual.

5. Traction Control Switch Test

Sub-steps:
1. Access the traction control switch on the dashboard.
2. Disconnect the switch and use a multimeter to test for continuity when the switch is engaged.
3. If the switch is faulty, replace it.
