2011 honda accord 93c86

[FxShaw]

2011 honda accord 93c86 this is the dump when read and when carprog verify...it said checksum verify error...I need to change to 25 miles only..need asap please

I think it is a 93c86..tachhosoft said it was at least..i solder wire in the back.

[gwee]

here u go :)

[FxShaw]

verify error :-(..its not writing...using carprog i think maybe the wiring is wrong?

[gwee]

use xprog or upa.

did u connect 12v to carprog?

[FxShaw]

Using a4 adapter from carprog with this diagram and still no luck...what am I missing?

[FxShaw]

no i didn't connect 12v...was i suppose to?

[gwee]

try using 12v and also interchange pin 1 and 8.

[XmoDDeR]

u need pins 1234 58 no 6

noooooooooooooooooooooooooooooooooooooooooooooo pin 6


noooooooooooooooooooooooooooooooooooooooooooooo pin 6

[FxShaw]

Tried pin 8 gray with before and samething..nothing.

[XmoDDeR]

carprog colors to chip pin numbers on 93c76/86 on solder points


pin1 white pin2 yellow pin3 brown pin4 blue pin5 green pin8 gray

[XmoDDeR]

voltage drop to 3.6 volts

[FxShaw]

ok i switch pin 1white with 8gray and noting...tried with 12v too

[FxShaw]

only way it read is when white wire..pin #1 is in the same as the pic i upload and no luck with vol 3.3

[XmoDDeR]

orig i sent u was correct i did 3 three times

[FxShaw]

I tried with yr wiring and no luck..i replace #6 red with #8 gray as yr diagram and still nothing

[XmoDDeR]

doing sumthing wrong its easy

[FxShaw]

So how can I read and not write?

[XmoDDeR]

pins 5 and 1 are hard points make sure u scuff points good to get good contact it works easy

[XmoDDeR]

just cause it reads , doesnt mean u read the right thing or it was a good read

heres how i did , dont follow colors follow pins

[FxShaw]

update so I took the damn needles out to find out it was a 93c76..program it and it was a success..only to find out when I put it back in the god damn cluster doesn't show any mileage at all..its blank..with code b1152 - gauge control module interneal error

What to do now :-/

[XmoDDeR]

new cluster ....i told u it was a 93c76 and u have no original dump, and i said never pull needles , never pull needles at least on this vehicle

[FxShaw]

Well I tried it as 93c76 and it was reading ok but not writing too..You don't think if I replace the 93c76 it will fix it?

[XmoDDeR]

does car start and run? and your gonna need a dump

[gwee]

please use other programmer instead of carprog to read and write.

[FxShaw]

yea it starts and run fine..but how was it I was able to write fine when connect direct to the chip? when I took the needle out and connect to the chip.I had no problem with it what so ever...why would I need a new dump btw? BTW taking the needles and puting them back wasn't that hard that all...it was really easy.


Unfortunately I only have one programmer.

[gwee]

Of course it will start even without that eeprom, key is not in the cluster :)

No one told you is hard to remove needles for this car :D

[FxShaw]

Thank you guys for all the help and support I finally figure it out..file was corrupt and when I went to write the mileage it wont write..solution: carprog always make a backup so I edit back up and figure out that even though I was connected directed to the chip it still wouldn't write w/o applying 3.3 voltage..which is weird and a first for me...anyways I fixed the same old cluster :-D!!

[XmoDDeR]

congrads ............. I sense a ripple in the force..lol

I have a cheap and reliable programmer for almost all of the eeprom chips. I found carprog, xprog and other clone software does not work sometimes. Reading eeprom chips without even removing is 100% success for me with this little programmers. You can buy in eBay for less than $50. Which is SP8-B version. Best thing with this programmer is the software. If you have not connected pins correctly to the board's eeprom, it will show you a graphical view of which pin(s) are not connected or wrong in connection. So, you will not make any mistakes. 100% works and trusted for me for more than 2years by now. I only use XProg, UPA or other programmers for read and write MCU's.

[XmoDDeR]

nice tool havent touched mine in a yr got as gift did pc bios with it , will dig out make soic8/dip and solder 8 for it

[phatty123]

fxshaw can you post that dump up please, I am looking for a similar file have a corrupt dash
