Hello
I understand the photo below has the GT1 menu in Greek, but I can translate.
Basically you need to connect the car to a strong battery charger and then also connect the GT1.
Do the initial diagnostics and then go to the testing menu.
Select the DSC unit and then 'activating parts'.
What you see in the far right is.
- Inlet valve front left
- Outlet valve front left
- Inlet valve front right
...
- Isolating valve DSC
- Return pump
The corner of the car that I am bleeding, while the bleeder is moving the brake fluid, I activate first the inlet valve (for 5 seconds the DSC will open it).
Then I activate the outlet valve (again 5 seconds).
I do the same thing another 4 times. In between waiting 15 secs or so.
The idea of doing the above is to let fluid pass from the DSC valves, replace the old fluid and eliminate any air.
I hope this helps.
