I have a 2015 Ram ProMaster (gas) and have been trying to get transmission temp to display. The ProMaster is branded as Ram in the US, but it’s origin is from Fiat as a Ducato.

I’ve read through this forum and the Promaster forum and have found there is indeed a valid transmission temp PID and have found data from Scangauge. I found the formula to convert it so that Torque will read, but I haven’t been able to get anything to work. I’ve never worked with Hex before, but from the guide I found, I think I was able to figure out the basics.

SG Data:
TXD: 10F122B010
RXF: 046205B00610
RXD: 3010
MTH: 0001 0040 0000
NAME: ATF

How I interpreted and converted from the info I’ve found:
OBD2 Mode: 22B010
Scale: x1
Equation: ((((A*256)+B*(1/64))-32)*5/9
Also tried ((A*256)+B)*(1/64)-65534

Also tried a few other equations that others had suggested before me.

Empty: OBD Header, Diag start/stop

Thing is, I’m not even getting data from that PID (“No Data”), and from what I’m learning, the equation is just how the data is interpreted. So, right or not, the equation isn’t making or breaking this. Along the lines, I briefly saw something about possibly needing to send a command to put the computer into a diagnostic mode. Could that be an issue? Would this data be read from CAN and I might need a cable to swap pins?

In my frustrating hunt in all of this, I’m also surprised that there isn’t some sort of Excel template that hasn’t been made to interpolate the SG data.

Any help is appreciated. Thanks!

TXD: 10F122B010
10F1 – most likely indicates the SP7 29-bit CAN protocol with the address DA10F1
What protocol do you use to connect Torque to your car?

Information about the connection protocol to your car can be found on the tab Adapter Status
