To ensure proper functionality, you will need a "security bypass OBD2 cable," which can be purchased from Amazon. Without this cable, the programming module may become unresponsive and get stuck in calibration mode. After obtaining and installing the bypass cable, which takes about five minutes, the programmer works as intended. 【Compatible With】This Turbo Actuator 6.7 Cummins Compatible with Ram 2500 ISB 6.7L Diesel (2013-2018), Compatible with Ram 3500 ISB 6.7L Diesel (2013-2018), Compatible with Ram 4500 ISB 6.7L Diesel (2013-2018) and Compatible with Ram 5500 ISB 6.7L Diesel (2013-2018).
