How many pedal presses before the pump runs?

To good to be true, but the sensors look okay, and no faults reported

I only got the nanocom yesterday and have not a clue what to make of the data!

If it can't make and maintain enough pressure, the lights come on

30 presses on the brake pedal before you attempt to remove the old accumulator.

Yes, yes, I will go through the decompression procedure before removing the accumulater.
Thank you again guys
