What does this fault code mean?

The transmission control module (TCM) can ask for a higher engine speed before a downshift, and the request is sent to the engine control module over the CAN network. The code concerns the engine control module not allowing the increase for some reason, for example when the speed is too low. The fault can be noticed during gear changes.
