Have you ever cleared the 313?
I found this really nice post:

""""a. Yes, VOL-FCR does all the codes and resets the warning light plus other things, BUT it does not display data from the various sensors.
b. OBD-II displays and graphs sensor data. For instance, you can see spark advance/retard under different engine running conditions, outputs from O2 sensors etc etc.
So, it depends what you want. I find it very useful to have the data from both products. The only overlap between them is codes from the engine ECU.""""
So your code reader doesn't do tranny codes. The FCR will also do ECC, instrument cluster, and seat computers.
