What up guys? We are running 2014 E4 with a 96v Bolt battery. Smoked the controller which was rebuilt (code 41) and now we are getting code 51 for
Low voltage. Battery is at 94v so we aren’t low, any thoughts? Main contactor possibly?

Thanks!

Check voltage at p1 after spoof.
Possibly p17.
What were the symptoms of bad controller?

Stone dead, no power to the car what so ever. I will check the pins for you tonight. Thanks Dave.

@Inwo after the spoof 83.3v, pin 17 93.3v.

Got me. That should work.
