If the pump runs while driving, then the electrical connection, fuses, etc. are all fine. The issue is that the computer is not commanding the pump to run the bleed cycle. The pump works fine otherwise, the difference is the electronic command to the pump.
I have no idea why the computer isn't initiating the bleed cycle. The way these cars are, there could be a number of reasons. Maybe the car has to be below a certain temperature. Or x minutes since last started. Who knows. Maybe it doesn't detect a chance in coolant level and has decided it doesn't need to run a bleed cycle.
I wouldn't worry about it.
