Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the battery to prevent electrical shorts.
Allow the vehicle to cool down if the engine was running.

2. Inspect and Clean Wheel Speed Sensors

Tools Required: Socket set, wire brush, cleaning solvent
- Sub-steps:
  1. Raise the vehicle using a jack and secure it with jack stands.
  2. Remove the wheel to access the wheel speed sensor.
  3. Disconnect the sensor’s electrical connector.
  4. Remove the sensor from its mounting location.
  5. Clean the sensor tip with a wire brush and solvent to remove dirt or debris.
  6. Reinstall the sensor, ensuring it is securely mounted.
  7. Reconnect the electrical connector.

3. Check Brake Fluid Level

Tools Required: None
- Sub-steps:
  1. Locate the brake fluid reservoir under the hood.
  2. Check the fluid level; it should be between the "MIN" and "MAX" marks.
  3. If low, add the recommended brake fluid type (DOT 3 or DOT 4 as specified in the owner’s manual).

4. Test Traction Control Switch

Tools Required: Multimeter
- Sub-steps:
  1. Locate the traction control switch on the dashboard.
  2. Use a multimeter to test continuity when the switch is toggled.
  3. If the switch is faulty, replace it with a new one.

5. Verify ABS Functionality

Tools Required: OBD-II scanner
- Sub-steps:
  1. Reconnect the battery.
  2. Start the vehicle and perform a self-test of the ABS system using the OBD-II scanner.
  3. Check for any error codes related to the ABS or traction control.
