I donīt know that scanner, so canīt tell you that much about it. Do you only want to use it for reading and resetting codes? Reading the codes on a WJ can be done using the key dance: ignition switch off/run three times and leave in run at the third time. The odometer will show DONE when all ok, or a fault code(s).
If you have an android phone, you could download the app " Torque" and just buy a Bluetooth dongle for the wireless connection with the jeep. There is a free version with already many features, or a payed one with more options. The free one let you check the fault codes, reset them and check many live data.
