These needles are easy to remove, no engines are damaged, with a fork

[lwood]

ok.. i found the chip on the inside.. its 93C86..
i also found rear pinouts.. but i get different read every time.. i dont know how to get the rear pinouts to read correct.. .. so until someone with more knowledge figures out the way to read with rear pinouts ... i will be removing needles.. for 2013 up Sentra..

i will post pitures of the rear pinouts and power up.

no its not next to #1... i always read in 16bit..
pin 8 is at the 4 locations in red..
i try all 4 locations. with different reads every time

[XmoDDeR]

read at 4.2 volts or lower .................ur tool is reading at 5v

Look for the silver crystal near the chip and join its contacts and try to read .

Look for the silver crystal near the chip and join its contacts and try to read .
when i read chip. it reads and writes just fine. its when i connect to rear pinouts i get the different reads..

i try with a different programmer USB upa

i try with usb upa regular adapter. doesnt even read it in 5V or 3.3v.
then i use captian crackers incircut adapter.. 5v i get different read every time.. just like with carprog.. thenn i try 3.3v it doesnt even read it..

UPA require Eeprom's pin 7 connection. (if you find this contact @ the back of board will be a bonus!)

don't remove the needles, just use the gold points as follows: 5-8-4-3-2-1 from left to right on above picture. Its proved. :bounce:

use carprog and bridge the crystal as COKOLO said before .

I know the thread a tad old but...What tool are you using to read the dump? Can you ues R270 and/or Xprog?

[lwood]

I know the thread a tad old but...What tool are you using to read the dump? Can you ues R270 and/or Xprog?
its just a microwire, use any programmer.. i use upa's .

[Wolfpack]

its just a microwire, use any programmer.. i use upa's .
I am new to all of this. What is a microwire? By saying any programmer you mean i can use 1 thru 8 on the wire harness that comes with R270 or Xprog. I have an UPA but i can't desolder

[Wolfpack]

No more help. Sorry i don't know what and how to use most programmers. I see the pinouts but do i use 1 thru 8 wires on R270 to read the eeprom?

[cklair]

R270 will not read it .upa or xprog is good tool .always save the original dump for back up
