Erase transfer case codes

Hi, my name is Devin. I am an auto repair expert with the Car Genius team here at RepairPal. I’m sorry to hear you're having trouble with your Suburban. To turn off the "Service 4-Wheel Drive" message and erase transfer case codes, you will likely need to reset the transfer case control module (TCCM). This can sometimes be done by disconnecting the vehicle's battery for about 15 minutes. However, if the issue persists or the code is related to a specific malfunction, the system will need to be diagnosed further. A professional scan tool may be required to read the codes and clear them from the system. If you need more advice, have any other questions about your vehicle, or would like to get connected to a RepairPal Certified shop near you, we have you covered. Give us a call at 877-913-1554, and we will happily help you out!
