The Chrysler/Dodge/Jeep 2018+ bypass cable by XTool is designed to interface almost all automotive transponder programmers that have the capability of programming 2018+ Chrysler vehicles. It functions by intercepting your programmer’s CAN high and low signals and passing them though the attached probes and 12+8 connectors. Depending on your plan of attack, you can tap the CAN wires directly in the STAR module, in the vehicle instrument cluster or at the wires which transport the information between the STAR module and the immobilizer. The OBD throughput will feed 12V back to your programmer to keep it charged if that feature is supported by your machine. Alternatively, the same outcome can be achieved by directly plugging the 12+8 connectors into the security gateway module of the vehicle. How to use (probes): Plug the main cable of your programmer of choice into the female OBD port of the adapter. Locate the star module on the vehicle. Location varies from model to model. Locate the plastic green strip with multiple white clips plugged into it. Locate the release lever of any one of the white clips. Probe your red (CAN HI) into the terminal directly below the release lever and the black (CAN LO) into the terminal below the previous terminal. Use your programmer of choice to select by vehicle or system type and program like normal. How to use (12+8 connector): Plug the main cable of your programmer of choice into the female OBD port of the adapter. Locate the security gateway module on the vehicle. Location varies from model to model. Locate and unplug the connectors currently plugged into the module. Plug in the 12+8 connectors directly into the module. Use your programmer of choice to select by vehicle or system type and program like normal. Note: The male OBD of the adapter is optional. Its only purpose is to pull power. If your machine is battery operated, the male OBD is unnecessary.
