Is cruise control effected by a failing ETM

When my ETM was failing, I noticed my cruise control wold not work properly but once the ETM was replaced it now works fine.

So does the failing ETM effect cruise?

Would you post more information on the symptoms of the failure and how it did not work properly. Did it hesitate and surge? Did it drop out? This information will help others identify a failing ETM.
Thanks,

Yes. Straight from VIDA is a list of what happens when the ETM detects an internal fault or the ETS (system) detects a fault in the accelerator pedal or a communication issue:

the accelerator pedal (AP) is ignored when braking
the cruise control cannot be activated
the engine speed (RPM) is limited using fuel shut off. The maximum permitted engine speed depends on the accelerator pedal (AP) position
