no brake pump action when opening drivers door

Hi all quick question

A few months back I bought an 07 with unknown history and a bad hybrid battery so the hybrid battery was replaced and straight after it had some codes for brakes along with a hard pedal which was quickly sorted with Techstream via the linear valve reset procedure. It has been driving perfectly ever since with no trouble codes but noticed the brake pump never kicks in when opening the driver door (RHD - Australia) no matter how long since the car was last driven, an hour or a week ..

There is no current trouble codes and the brakes are working normally and pumping up with every few presses of the pedal when driving.

When the drivers door is opened it gives a little click and a clunk like they do but the pump does not come on until driving ..

PS the door switch and interior light are working fine so the car definitely knows when the door has been opened!

Any clues guys?

Thanks ..

Cheers
