If you order a Mini VCI cable (only $20 online) and install Techstream you can look at the accumulator pressure and even chart out when the accumulator pump runs.
I was having an issue with mine and could see that the booster motor cycles until the accumulator voltage reaches 3.8V. The booster motor will automatically run once the accumulator voltage drops to 3.2V.
Having realtime accumulator voltages was very handy for diagnosing my issue. Also, the ability to bleed the system with Techstream is awesome.
Save yourself even more money next go around by ordering the cable and installing techstream. The technician likely only did the steps I just listed.
