Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is on a flat surface and secure it with wheel chocks.
• Disconnect the negative battery terminal to ensure safety.

2. Inspect Wheel Speed Sensors

• Sub-steps:
  • Locate the wheel speed sensors at each wheel hub.
  • Clean any dirt or debris from the sensor area to ensure a proper connection.
  • Check the wiring harness for frays or breaks; repair as necessary.
  • Use a multimeter to test the resistance of each sensor; replace any that are out of specification.
• Tools Required: Multimeter, socket set.

3. Check Brake Fluid Level

• Sub-steps:
  • Locate the brake fluid reservoir under the hood.
  • Inspect the fluid level; if low, top off with the manufacturer-recommended brake fluid.

• Tools Required: Brake fluid, funnel.

4. Inspect ABS Module

• Sub-steps:
  • Locate the ABS module, usually found near the master cylinder.
  • Check the module for any visible damage or leaks.
  • Use the OBD-II scanner to clear any fault codes related to the ABS system and recheck for codes after a test drive.
• Tools Required: OBD-II scanner.

5. Test Traction Control Switch

• Sub-steps:
  • Locate the traction control switch, typically found on the dashboard or center console.
  • Use a multimeter to check for continuity when the switch is pressed.
