Programming
2012 Fiat 500 c Pop 1.4L (EAB) 5-spd

Hi all, trying to program a body control module in this 500. I found a great video on YouTube explaining how to set it up and get tool verification. All seemed to go great until trying to read the vehicle. If I try and try I can eventually get the serial number from the used module I installed, it pops up then disappears and tells me I have no communication with the vehicle.

I guess I'm wondering if the snap on 2 is compatible with Witech, if anyone is using it regularly? I also tried an Autel elite with the same results. It doesn't look like either of these are recognized as recommended tools.

You mean no comm with the used module or just no comm in general? also I think you need a Passthru 4/cardaq plus 3.

I do have communication with the module via scan tool (codes, bi-directional controls, etc) but Witech will not communicate with the vehicle.

For my part, I use GM's MDI interface to use Chrysler's Witech. I know, and to have tested it, that the Autel interface does not work.

I've been using the Autel Maxi Flash J2354 with win2tech. You have to use the passthrough to connect to the modules

Thanks Josh, hoping you could elaborate on this. Do you mean the pc MaxiSys to be opened on the background before opening WiTech?

I have the cardaq2 and it says right at the bottom of the instructions that it will not work. I did use it to update a hvac module, but that was before the token came out, so I dont know if that changed anything
