Can I bleed the stroke simulator without starting Linear Valve Offset?

    Hi everyone,
    I replaced only the brake booster pump and now I want to make sure there is no air left in the system. (sometimes I hear sounds near the brake pedal that seem like air in the system).

    In Techstream, the only place I found that bleeds this part is Utility - ABS actuator has been replaced. But after that, Techstream wants to run Linear Valve Offset.

    Can I press EXIT when Techstream asks to start the valve calibration, and will that end the procedure safely without storing a permanent fault or causing a problem later?

    If that is not safe, is there another working method to bleed the upper circuit / stroke simulator without forcing the calibration step?

    I suspect the calibration may not complete successfully (there are many reports about this on this forum), so I would like to avoid that step if possible.

    Thanks.

    And this is a used actuator are you able to power the car it came from ,? In tech software it's always asking yes or next all you gotta do is say not yes or such . I'd have to power the Toyota software up to run through the nonsense to see what it exactly says but it's constantly asking to proceed or no or I personally haven't had any trouble running the linear valve offset on used actuators I've put in four or five all on my own cars one or two on customers cars I've never seen again .

    You should be able to bleed all that without tech . Done it several times
