Yes. Because we handle all the programming, no further setup or calibration is required after installation. Simply disconnect the battery, swap the old module with this new one, reconnect the battery, and your 4WD system will be restored to full functionality.
What are the most common signs of a failing TCCM?
The most common symptoms are a “Service 4WD” or “Service Four Wheel Drive” message on your dashboard, flashing indicator lights on the selector switch, and the inability to shift into or out of 4-High or 4-Low.
