Hi
I use the torque pro app with a Bluetooth adaptor. I’m trying to read the transmission fluid temperature (TFT) on a 2016 Acura MDX. I tried pretty much everything found on mdxers.org and other sites with cars having the same motor (odyclub.com or ridgelineownersclub.com).

So i have the following information from a guy on mdxers.com that uses succesfully a scangauge 2 to read TFT on the same car as own.

How do I translate SGII to torque PID??
Transmission Fluid Temp (°F)
TXD: EFF1229023
RXF: C32200000000
RXD: 3808
MTH: 00090005FFD8
NAME: ATF

Thanks for your reply!

The protocol is ISO15765-4CAN29/500

I tried PID 229023 with or without the suggested header, as well as with or without the diagnostic start command (ATH0\nATCAF1) with no success. I tried the other start command found on the provided link (atsp7\natshda1df1 , ATCAF1, ATH0, …).

All in all I always get “NO DATA”, so no raw hex response.

try this
Header: DA1DF1
CAN 29 Bit
Pid: 229023

atsp7\natshda1df1

Is there another pid, e.g., 228220, that
may work with your vehicle?

I am wondering if a diagnostics enable
command is needed to get pid to respond.

Not aware of what command is needed and
am at the limit of my knowledge.

The command atcp18 sets the priority byte for
CAN 29 bit headers. Default is 18. Any chance
it has been changed?

I would be curious if Torquescan can find any
mode 22 pids.

Edited.

Thank you all for your input. I don’t know any pid that could work. Everything else in torque works nicely though, like collant temperature and rpm to name only two. Why is the transmission fluid temperature so tricky to obtain?

Whatever what i use does not work (229023 or 228220)
