  3. 3Check the brake fluid level and inspect for leaks in the brake system.
  4. 4Verify the condition and operation of the ABS module.
  5. 5Test the traction control switch for functionality.
  6. 6Check the vehicle’s battery voltage, as low voltage can affect traction control operation.

Solution

Solution

1. Preparation

  • Gather necessary tools and parts.
  • Ensure the vehicle is parked on a level surface and the ignition is off.
  • Disconnect the battery to avoid any electrical shorts during repair.

2. Inspect Wheel Speed Sensors

  • Tools Required: Socket set, multimeter
  • Remove the wheel covering the sensor (if necessary).
  • Disconnect the wheel speed sensor connector.
  • Use a multimeter to check for continuity and proper voltage output while spinning the wheel.
  • Clean or replace the sensor if it shows signs of damage or fails the continuity test.

3. Check Brake Fluid Levels

  • Tools Required: Brake fluid tester (if available)
  • Open the hood and locate the brake fluid reservoir.
  • Check the fluid level; if low, top off with the manufacturer-approved brake fluid.
  • Inspect for any visible leaks in the brake lines or around the reservoir.

4. Inspect ABS Module

  • Tools Required: Socket set, torque wrench
  • Locate the ABS module (typically near the brake master cylinder).
  • Check for loose connections or damaged wiring.
  • Ensure the module is securely mounted; re-torque connections to manufacturer specifications.

5. Test Traction Control Switch

  • Tools Required: Multimeter
  • Locate the traction control switch inside the vehicle.
  • Use a multimeter to test for proper function and continuity when the switch is engaged and disengaged.
  • Replace the switch if it is faulty.

6. Reconnect Battery and Clear Codes

  • Reconnect the battery.
  • Use the OBD-II scanner to clear any fault codes.
  • Start the vehicle and check if the traction control light remains off.

Verification

After completing the repair, verify that the issue has been resolved:

  • Test the affected component to ensure it functions correctly
