    yes. And the battery is hooked up to the wall. And the parking brake on, etc.

    What sometimes trips people up is forgetting to release the parking brake before the linear valve offset calibration procedure.

    If the booster with master cylinder assembly has been replaced, Techstream allows you to indicate so before you initiate the bleed procedure. And once the process gets going, it will automatically perform the offset learning at the end. I forget if it also warns you to release the parking brake before you begin that part of the process.
