I've run into an issue with a 2010 Jeep Wrangler.
We've recently replace the ECU with a brand new one from the dealer and unfortunately, it was not pre-programmed for the vehicles VIN. All local mobile programmers are either too busy or have not responded and I am starting to wonder if there's a reason for this.
Snapon scan tool was unable to write VIN to ECU, but have been researching other methods to do so without spending thousands on new equipment that will only be used once. After researching a little with little success, I have come across the ISO 15765-4 HSCAN protocol as the implemented protocol for this model jeep, can anybody concur?
Basically, I am wondering if anybody has had success with writing VIN to Jeep's ECUs for the models after 2008 using either Snapon scantool or HSCAN DLC to USB connection, possibly using the ELM327 IC-based connection or must we submit to Chrysler's proprietary headache and send the vehicle to the dealership to be initialized?
Any guidance would be greatly appreciated, thank you!
