This code is nothing more then informational. Meaning it provides no diagnostic information but just telling you that the TCM told the PCM to turn the check engine light on.
Most generic scan tools only communicate with the PCM so the OEMs put this in there so that we know we need to look further.
So your scan tool communicated with the PCM and found that there is a code in the TCM so we need to use a scan tool that can talk with the TCM to find out what this code is.
Here is a guide that will help with this:

Below is all the detail on this code from the manual that will give the info that you need.
Please let us know if you find the code in the TCM and we can figure out what is going on.
Thanks
