you will need a long usb cable if you are doing this on your own as you will need the laptop under the car with you and it plugs in to the car by the drivers left knee, so i think 5m cable is needed.
you get to the AYC ecu controls in the bottom right of the evoscan window. change the ecu to ayc top middle of the screen , you will see the pump drive and the op check L and op check R solenoids in the bottom right of the evoscan window dont both with the air bleed button i dont know what this is supposed to do but it does not run the pump to fill it with fluid and create pressure..
just remember that once you click the activate button the pump and the solenoids will engage for a set period of time i think 5-10 seconds.
so you need to have enough fluid in the reservoir for that period of time.
when you initially install and new or refurbed pump it will be empty of all fluid so it is best to fill the inlet pipe with fluid before installing the pump in the car then at least you will not be fighting a complete air lock.
once pump pressure is achieved which is just a case of running the pump multiple times with the pump drive button once the pump is full of fluid the pump noise will change and the pump will start to shut off, it will not run for the full time the pump drive is active. this shows you the pump has reached full pressure.
you can operate the left and right solenoids.
when the solenoids are activate you just open the bleed nipple for that valve to allow air to bubble through. just close the bleed nipple at any time even if the valve if still open. it does not matter. you will need to run the pump every so often as you are bleeding pump pressure away everytime you open the bleed nipple and let fluid out.
but don't let the pump reservoir run dry as you will need to start the bleed process all over again.
it can take a while for all the air to come out of the bleed nipples so i run the bleed cycle until i get fresh fluid coming out of the nipple, put a pipe on the nipple and collect all the fluid coming out in a small clean pot. when i say small i mean small, ideally you want the pot to be smaller than the reservoir in the boot then you can never get air into system as there will always be something left i the reservoir in the boot.
this gives you two things,
one, is you know how much fluid has been pumped out, the reservoir in the boot is not very big so keep topping it up.
two, you can pour the fresh fluid you have collected in the pot back in the reservoir so you don't waste it. as long as it was a nice clean tube and pot to begin with.
then you can run the bleed process over and over again to ensure you do not have any last bubbles of air in the system.
the only tricky bit is remembering to refill the reservoir.
if you use a small enough pot then even refilling the reservoir this is fool proof.
