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.

 

Let me explain what happened in a bit more detail.
I had an ABS accumulator pressure leak (the pump was running every ~15 seconds). I installed a used pump and accumulator, but kept my original actuator.

After that, the system started to hold pressure, but in a strange way. The new accumulator can hold pressure for up to about 2 hours... but after some time the pressure starts dropping again and the pump starts cycling frequently again.

If I run the Actuator Air Bleeding Pattern 2 active test, the accumulator starts holding pressure again for a while. That can last from 10 minutes to even 1 day, depending on driving style. So this active test helps, but only temporarily.
So technically, the new accumulator itself can hold pressure.

That is why I think the leak is somewhere in the actuator. I have a few possible theories:
1. dirt in the system that keeps getting back to the valves
2. a faulty valve inside the actuator
3. air still trapped inside the actuator (I also hear a hissing sound near the brake pedal area)

My main theory is air trapped somewhere in the upper part of the actuator.
I think that if the valves were just dirty, or if a valve did not seal at all, the situation would not improve at all after the Actuator Air Bleeding Pattern 2 active test.

That is why I want to bleed the system, including the stroke simulator at the upper point, but without the final valve calibration step. There is still a chance that the valve inside the actuator is faulty and may not pass calibration, and I do not want to turn the car into a brick
In my place, it is very hard to find a used or new actuator for my Prius.

That is why I want to start with bleeding the air first, without calibration.

PS: To be honest, the shop that replaced the pump told me they fully bled the system, including the stroke simulator, but I opened the panel and there are no tool marks on the bleeder screw at all. It looks like they just installed it and ran a few “bleeding” tests, not the Utility procedure. So I want to understand the problem myself and identify the faulty part more clearly.

 

I could start the Utility - ABS actuator has been replaced procedure and when it reaches the point where it asks for the valve offset calibration (which comes after bleeding the stroke simulator) just press Exit.

However, I am not sure if this Utility requires the full procedure to be completed, or if exiting at that point could cause issues, or leave a fault in the system indicating that the valve calibration was not completed.
