Hi,
Could you please shortly explain what did you do to fix your issue ?
It's very important as i'm figthing since weeks with same issue and, searching on internet a lot, not so many people succeed to fix this issue (display of odometer as 8888).
I have same issue, guessing also that the EEPROM 93c86 is corrupted, but i need some confirmation before buying either a new EEPROM + programmer or a new cluster...
Thanks a lot for your understanding ; your answer could help more than one guy.

Hi,
For people who could face same issue (Instument Panel Control - IPC odometer displays only 888 ; same for gearshift position for the OPEL ANTARA 2008) in further time, here is the solution :
Issue is probably created thanks to a low battery voltage or a almost-dead battery.
Thanks to this, the EEPROM 93c86a soldered on main PCB of the IPC got corrupted.
When i say corrupted, it means that it lost the VIN number of the car, lost PN, SN and variant configuration.
At same time it happened to me, i got additional variant (not present on the car ; for instance, park assistance, speed overspeed alarm...).
Well, here is the process to follow :
_ Buy an universal programmer of EEPROM (example TL866CS)
_ Buy one or two 93C86a spare parts (needed only if you are unlucky and destroy parts)
_ Search on internet (soft dump russia site) for a dump file (copy of existing EEPROM for your car, search by PN) ; download it
_ Open the .bin downloaded and modify the VIN numver according to CARPASS data for your car
_ Remove the main connector on the IPC back
_ Lock your car
_ Teardown entirely the IPC
_ Unsolder the 93c86a from the IPC board (not possible to progamm it insitu)
_ Read the EEPROM content and save it as a backup
_ Flash and verify the EEPROM with the dump file .bin downloaded
_ Solder the EEPROM back to the board of the IPC
_ WAIT 1h30 min between the time you lock your car and the time you will unlock it !!
This is important as it seems there is a timing where the system doesn't look at the EEPROM content ; so new data will be taken ONLY after this timing.
_ Assemble again the IPC
_ Unlock the car
_ Connect the back connector again
_ Turn on the start key (just supply the system) ; You should get the new mileage (taken from the dump file)
N.B.: If you want to adapt your IPC to the real previous mileage, you can either take the information from the backup file you created at real beginning OR use Tachosoft to find what should be the values and position in the memory for your mileage)
On internet, some people said that doing a reset (blanking the VIN in the ECU) on the BCM and flashing it again (flashing only the VIN) is enough to fix such kind of issue. This is probably true on other Opel's cars, but not for the Antara.
Other comment, i tried to use OPCOM to do first tests. It was great to access to different ECUs and detect that data from the IPC were wrong (for instance written as ÿÿÿÿ which is FF in the memory). But then, as some menus were grey, i tried to downgrade the firmware (V1.7) to an older version(V1.39), and once i launched again OPCOM or VAUXCOM, the software detected the old version, flashed automatically the firmware to a version V1.45 and then, no possibility to communicate with the interface anymore. Even after changing the µcontroler PIC18F458 (from China ; which was a fake one) by a real from Microchip (flashed with V1.7 and others), it was not working anymore. Driver for the FTDI inside were ok, but well...after hours, i gave up.
So, don't hesitate if you need any support ; on my side, i spent dozen hours to fix my issue !
Thanks.
