Use DP3 . Opel Combo = Opel Corsa OBD.

Are you sure you in the right occupation? To even ask what tool to use to change mileage on a combo, even a school kid knows to use opcom to do mileage. I am glad its not my vehicle you working on.

Nope, not sure, but got to start somewhere like with everything else.

I'm playing with car that's about to be on dump soon, so nothing to lose.

Tnx for help anyway,

Just use opcom on corsa combo and it will do mileage no problem.

Better remove fuse otherwise you might need a radio code !!!!!!!

jaja.

was just an example!

[Autowave]

Sorry to resurrect an old thread, but I've just changed ECU/IMMO/clocks/bmc in a Corsa C 2005. Need to change mileage, gone through OPCOM EEPROM menu, held down reset button, opcom shows writing is successful. But mileage ondash is still the same!
I have tried disconnecting battery for 2 hours, remove both dash fuses for 30 minutes and also disconnecting dash for 20 minutes!
Any ideas on what I am doing wrong?
Don't know if this is relevant but every function on OPCOM works ok apart from when I try to read instrument fault codes, sometimes it says ecu timeout check ignition is on.
Any help would be appreciated

[batandball]

Some 2005 up Have a different connection via OBD

[Autowave]

Ok, so what is that connection? Also then surely it would not tell me writing success?

[batandball]

This is tacho universal picture
This is plug on back of the dash
green wire k line if you know the wires on your OBD plug then wire to the back of dash

[Autowave]

Ok,so shall I connect to my OPCOM interface? using just +,+,- and K line?

[batandball]

yes
look at this link number 8 onwards

[batandball]

Did you sort it mate

[Autowave]

No, I connected dash to psu and used pin 12 on opcom interface direct to dash. But opcom menu just says changing init. Do I hve to use power from opcom as well?

[batandball]

look at the k line pin at the dash end from picture and put tester to the OBD socket on van for k line

[javyb]

Check fuse box under bonnet and make sure the 3 three 7.5 amp fuses at top right are present. I had a corsa c which mileage wouldn't change checked fuse box and two fuses were missing which were supposed to be there

[smartymarti]

tryt putting on chocks and drive fast in reverse to required mileage , works every time for me

[Autowave]

All fuses are present. I'll try as above by connecting it all up as normal but bridging pin 12 of OPCOM directly to k line pin behind clocks. I will try and report.

[Autowave]

Wish I could change via EEPROM on this!

[PremierD]

Mate .. you sre changing it in the eeprom .. just in this case it's the one thats in the NEC .. mcu :)

[Autowave]

No I meant physically reading an EEPROM and editing the dump. I try and avoid tinkering with MCUs. But hopefully the method I'm about to try will work.......

[batandball]

If you wire it right it definitely works

[Autowave]

Right, I must be doing something wrong. Firstly sorry for being a pain in the backside I understand this is a very simple process but it doesn't seem to be working. I have attached 2 photos of hat I am doing. I have stripped the kline wire from behind the dash and also pin 12 from behind the obd port and joined them together! Is that not correct?193648193649

[batandball]

193652Pin 7 is K line on car OBD

[Autowave]

I have tried pin 7 but still the same, I can't even get measuring blocks on the instrument. I think I will have to put it down to having a poor quality OPCOM interface. Thanks anyway.

[batandball]

Wot machines you got other than opcom

[Autowave]

For vauxhall just OPCOM, programming wise I have UPA, CDH programmer and a few other bits

[batandball]

Cdh gear does it from back of dash, Colin was the first to sort that out
Will post picture tomorrow
