    On techstream when the car is running it's throwing code for cell block 2 becomes weak. Yesterday I finally identified which cell was acting unusual and replaced both cells in cell block 2 with cells from a 2014 prius that I got new. I balanced everything before test driving and when I get on the gas at about 31 mph the triangle comes on and when I decrease speed down til the motor cuts off the triangle comes on. Any ideas?

    The 2014 modules might not be a good match to your old 2006 modules. Did you scan for DTCs yet? That's
    the first thing I would do.

    Are you certain you replaced the correct modules? Block 2 is on the passenger side of the battery. Some have
    made the mistake of replacing Block 13 (which is near the battery ECU on the driver's side) instead.

    Check your engine oil.

    Really!

    Low oil will slosh around on acceleration and deceleration. This will cause the triangle to go on and off.
