Re: TCU upgrade not working

A thread on here talks about the upgraded tcu needing a higher voltage from the battery to operate. Your 12V may need changing, and you could stick a trickle charge on it for a few hours to bring the volts back up.

If you could read, you would know I already replaced the battery, and the Dealership can not make it work either. But those that can read know this. :roll:

I have now replaced my failed coolant pump #1.

$502 dollars shipped. Took about 1/2 hour to replace and I did not spill a drop of coolant.

Now if I could just get the TCU working, My 75k mile LEAF will be in great shape again.

I will be selling it for $3k next year when my Model 3 gets made. :mrgreen:
