BMW F650GS Dakar

[cristim86]

Hello!
I have a 2003 Bmw f650gs Dakar ABS.
Odometer displays ------, everything else is working fine.
After much research and searching on many forums and i understand that there may be eprom corruption or imposibility to read eprom data.
I belive this happened after i accidently used the main kill switch while running/parking (not 100% sure).
PCB is kind of clean, i already replaced some capacitors, odometer still displays -----.


Can anybody provide help with the following:
1. what exactly do you use to read/write/view/edit eeprom data; i have basic some electronic skills, doing lots of hobby projects; i saw that 24c02 is on the i2c bridge
2. is there any post/thread with the algo for the eeprom data ? i saw in other posts that everybody posted their original eeprom data first
3. has anyone else encountered this problem ?

I am trying to fix it on my own, maybe i have a chance.
Any help will be highly appreciated. Here are some pics before cleaning and cap replacement.

Hello!
Thanks for reply. I haven't done anything like this before, any help will be highly appreciated.
What software/hardware should i use ? Do you recommend taking the chip off ?
What do i do if i can't read anything from the chip ?
Thanks,
C.

You can read incircuit with a good programmer, if its off the board any programmer will read a 24C02.

Read the rules.... There is information about when this happens. Browser cache cleaning is one of them.

I've tried the writing the file above and starting/powering the board, unfortunately not working, still - - - - - instead of any km. Any other file suggestion or what else to check on the board ?

hello I found the 4 100k pullup resistors marked 104 on the sda - scl - E1 - E2 pins of the 24c02 at more than 300k, the one on sda even 600k in fact the signal did not exceed 2 volts seen on the oscilloscope. I replaced them but it continues to display dashes ------- perhaps the eeprom is corrupted? since the bike is not mine I have not tried to connect it completely but I only powered gnd - pin 1 +12 volt pin 2 +12 switched.
Thanks in advance Mauro
