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:

after 4 months. 4 visits and 6 days total at dealership, my TCU now works. However, my battery is now down to 66% of original life left, at 78K miles, I now can not travel more than 50 miles. Car is 5 years old and trade in value, 3 to 4 k. There is no way in hell I am buying a new battery for this.

My Tesla battery is so out performing the Leaf battery, It is stunning. Tesla batteries tested and have already proved that they can go 200k with out losing more than 10 %. Leaf lost 33% in less then 78K miles. New Tesla batteries are testing out at 500K miles before 20% loss. I will never buy Nissan again, and will be getting another Tesla. Which also hold their value way better than a Leaf.

Good bye all you fools living with a LEAF. Junking mine. :mrgreen:
