The Nissan Sentra 2020+ bypass cable by XTool is designed to interface almost all automotive transponder programmers that have the capability of programming 2020+ Nissan Sentra vehicles. It functions by intercepting your programmer's CAN high and low signals and passing them though the 16+32 connectors bypassing the security gateway module of the vehicle. This allows access to all module on the CAN network for diagnostics/by-directional controls/programming.
