    I tried to post the video but it’s too large. It’s kinda hard for me to tell when
    The pauses is between the numbers.
    I’m thinking based on the code I posted the picture of which I think is 22-13 Engine Speed Signal Calibration Not Performed. Maybe this would have an effect on Jake??

    That will be a great help. In status, check operation of clutch switch, brake switch, jake on/off and stages. In special tests, you can also actuate the solenoids with engine off and hear if they work.
    You will need the probe and cable if timing needs calibrated.
