Yes because I swapped your bytes. If you write my file as x16 will work.

[hafido1983]

hi guys when i test all these files the mileage display is not light no thing
when i return the original file same problem who has the tested file
please i need help
thanks

If you have error when you put orig file back then your problem is with soldering or your programming of chip. Did you read original as 8 or 16 bit as when I swapped bytes on your original it looked ok and I could see the mileage so looked to me as you read as 8 ?

[hafido1983]

i read it by 8..
i solder it well ..

[88diablo]

And if you put orig file back by 8 it does not work?

[hafido1983]

And if you put orig file back by 8 it does not work?
yes the orig doesn't work .

[88diablo]

Did you take chip off to read or did you read in circuit?

[hafido1983]

i take it off only 93C46
please i need the help

There is nothing wrong with the original file. This vehicle is perfectly easy to do with tachosoft. It is already read in 16bit. The only difference is that some equipment read bytes swapped. This file is good. It is not 8bit. It is 16bit. Just write it back the same as you read it.

[hafido1983]

friend i test this file but doesn't work

[88diablo]

Just a thought but I think I did Isuzu Rodeo last week which similar and after you put dash back in I had to press mileage trip reset button to show mileage. Did you try this, if not try it may work.

[hafido1983]

I put it and i connect two connectors in dash but no thing i didn't mount it all dash

[88diablo]

Yes connect up but I meant try and press the trip reset button to see if mileage displays. Just a thought that's all.

[hafido1983]

yes friend i press many time
the buttn near display of km but no light no km i don't see any thing

[hafido1983]

my dash like this
when i connect the connectors I PRESS the button no thing

[88diablo]

Have you tried in car or just on bench?

[hafido1983]

friend i try many time in car

[88diablo]

You need to get original dump working before you try anything corrected. You need to check check and check again the tracks to the chip and the soldering. Program the chip with original dump with the same programmer the same way you read it. Other things to try are new chip just incase old one is damaged but doubtful or as when I looked at your original file I could see correct mileage but with bytes swapped so presumed youd just read as 8 not 16. If your programmer has swapped bytes when reading then I would of thought reprogramming same way would be ok but you could try swapping bytes of your own original file to be sure. If you cant get original file to work though it is most likely bad joint, broke track or solder splash on board somewhere.

[hafido1983]

just what i want to know my file and the other which i tested is correct or no...?
because this what i do don't touch any thing in dashboard only the eeprom 93C46

[88diablo]

Your original file looked ok to me when I swapped bytes so I presumed you read as 8 not 16. When I swapped bytes I could see your mileage in the last 2 lines. I corrected for you and told you to write back at 16 as this should work. Im not familiar enough with this car though to know that your full dump was ok so maybe you have an error in rest of dump. Try and search forum for other dump for this car and try.

[hafido1983]

that what i need who has has tested solution for this type of car ...?
thanks

[88diablo]

You nee to state exact model with engine etc and year and maybe someone give you clean dump then start from fresh.
