Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, jack and jack stands.
Ensure the vehicle is parked on a level surface and the engine is turned off. Disconnect the battery to prevent electrical shorts.

2. Inspect Wheel Speed Sensors

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Remove the wheel corresponding to the wheel speed sensor being inspected.
3. Locate the wheel speed sensor and visually inspect for damage or debris.
4. Use a multimeter to test the sensor's resistance; replace if testing indicates a fault.

3. Check ABS Module and Wiring

Sub-steps:
1. Locate the ABS control module, usually found near the brake master cylinder.
2. Inspect the wiring harness for frayed wires or loose connections.
3. Use a multimeter to check for continuity in the wiring; repair or replace as necessary.

4. Test Traction Control Switch

Sub-steps:
1. Locate the traction control switch on the dashboard.
2. Disconnect the switch and test its functionality with a multimeter.
3. Replace the switch if it does not operate correctly.

5. Brake System Inspection

Sub-steps:
1. Check brake fluid levels in the master cylinder; top off with manufacturer-specified brake fluid if low.
2. Inspect brake lines for leaks or damage.
3. Examine brake pads and rotors for wear; replace if necessary.
