Repair Instructions

Addressing Diagnostic Trouble Codes:
- If any DTCs were found, research the specific codes and follow the recommended repair procedures related to each code.
Repairing or Replacing Wheel Speed Sensors:
- If a wheel speed sensor is faulty:
  - Disconnect the battery.
  - Remove the wheel, then the brake caliper and rotor (if necessary).
  - Locate the wheel speed sensor, disconnect it from the harness, and remove it from its mounting.
  - Install the new sensor, reconnect the harness, and reassemble the brake components.
  - Torque all fasteners to manufacturer specifications.
Brake Fluid Level Check:
- If the brake fluid is low, top it up with the specified brake fluid (usually DOT 3 or DOT 4).
- Inspect for any leaks in the brake lines or at the calipers.
Resetting the Traction Control Light:
- After performing the necessary repairs, use an OBD-II scanner to clear the stored trouble codes.
- Verify that the traction control light turns off after clearing the codes.
Test Drive:
- Conduct a test drive to ensure the traction control light does not reappear and that the system operates correctly.
- Monitor the vehicle’s performance, especially during turns and slippery conditions.
Final Inspection:
- After the test drive, conduct a final inspection of all connections, fasteners, and components to ensure everything is secure.

Conclusion

If the traction control light remains on after performing these steps, it may be necessary to consult a professional technician or visit a Toyota dealership for further diagnosis and repair, as the issue could be more complex involving the traction control module or ABS system.
