Just found that using IAT2 from the TCM in the same PID list as IAT from the ECM does not work. !t causes a $001 error, which really doesn't make any sense, because thats an internal USB error code.
The IAT PID by it self does not cause the error, however, I believe it does display incorrectly or is not a valid pid in that it reads a constant -32*C with 70*F AAT temps.
