Keith Browning Posted April 20, 2019 Share Posted April 20, 2019 We had a 5500 in for the SCR recall that includes a PCM re-calibration to address the removal of the ammonia sensor. When connected, there were no calibrations showing for the vehicle. Usually there is one or for these vehicles two, one with the recall performed and one without. We discovered that the VID block was blank so it makes sense that calibrations could not be identified. I am not well versed with Chrysler - does anyone know if there is any option like Ford has in recovering modules with As-Built data or do we actually need to replace the PCM? I believe the gents on the other side of the shop are going for the new PCM but I was just wondering... Quote Link to comment Share on other sites More sharing options...
8WA Sman Posted April 22, 2019 Share Posted April 22, 2019 There should be an option to check ECM/PCM vin. You may also be able to try replace/reprogram ECM and I think this is done in the wireless control module. Quote Link to comment Share on other sites More sharing options...
Keith Browning Posted April 22, 2019 Author Share Posted April 22, 2019 The module ID is blank and he cant program it as a result so it awaits a PCM at his point. Quote Link to comment Share on other sites More sharing options...
