toyota dash dump help please if you can

[carlford]

My 00 celica had the dashboard ripped out of it last weekend and this weekend i went to a junkyard and got everything to put it back. Everything works but I need to change the mileage to what my stolen was at. I got a cluster with 185000 miles on it and need to be near 88000 miles. I read the 93c46 with a microchip programmer that i borrowed but i had to short 2 pins on the oscillator (crystal) before i could get a reading. I can pm this dump to you or you can look at it here and maybe tell me what I need to change. I have hexworkship and can edit the file as needed. If you can help or have a copy of a late tachosoft maybe you could look at this dump and make sure I read it right. Before I shorted the crystal all I got was 0000 0000 's and when I found that you had to short it I got this.

This is for first and last time,you have to update your profile with city and country before posting any thread,regards,Huzefa.Car type: Toyota Celica Denso - 93c46 - 2000-2002 year
The mileage is stored in the next lines:
0000: xx xx xx xx xx xx xx xx A9 CB ED xx A9 CB ED xx
0010: A9 CB ED xx xx xx xx xx xx xx xx xx xx xx xx xx
where the next bytes:
A9 CB ED - is a mileage,for 85000 miles, you have to change the hex-85000km = FFAFF7

Thanks huzzen27 for your reply.
I get what you got a camry but I did not have a calculator for a celica. Looking at the dump I posted it is no where near right. I guess I corrupted it.
If any one has a known good dump for a 00 celica in miles please let me know.

Carl

PS I did put in a city state country in my cp.

thanks again and those dumps are like what i am used to. I am going to write one of those to the chip which i did take off and now get a stable reading on 2 different programmers. I must corrupted it reading it in-circuit before i jumped the crystal. I will let you know the outcome.

I'm assuming that the 93c46 IC is a SMD type chip. If that is the case remove the chip and run enameled magnet wire to each pin and then solder it to an 8 pin dip socket for reading and writing. Wire another 8 pin dip socket to the board and you can replace it when finished.

If that is too much work, then look up the pin out of the 93c46 on icmaster and cut the VCC and I/O wire that supplies the EEprom. You can then read it without corruption. You can solder the cut lines when your finished. Good luck
