Need to replace tb2-160 relay in uch if you do will it need reprogramming?

Replacing the TB2-160 relay in the UCH (Unit Control Hub) typically does not require reprogramming, as the relay is primarily a hardware component that functions within the existing system parameters. However, it’s essential to check the vehicle's service manual for any specific procedures or requirements related to your model. If the replacement affects other systems or components, reprogramming may be necessary. Always consult with a professional to ensure proper installation and functionality.
