What the grey one inside the car?

You shouldn't need to remove the EEPROM it should read fine on the board.

Whats happened there is you have a corrupted EEPROM. I found all this out when playing around swapping eeproms from higher boards.

Did you say you had a 1.3 without S/S and Flip switch C/C?

Ahh, the grey 12 pin plug in the car... is sort of round, has different sized contacts in it, and is where the loom that goes to the exterior socket plugs in to the loom to the trailer module.

i have a china special eeprom reader.. don't laugh too hard... one of those £3.99 CH341a things, figured it reads 24 and 25 series ic's, the eeprom on the ipc being a 25L080 it'll do the job... but i couldnt get a reading either in circuit, or out of circuit in a sop8 quick release holder (i did get all 00's once instead of FF's from no chip present gets)

but i  didnt try soldering it to an adapter board as by that point i thought i had wiped the eeprom, so put it in the up level ipc just to see what would happen. 

I have some 25L080 chips coming in the post, and will try to get a dump again and clone it (if i have to buy a mini-pro to do it, then i will have to) then i want to wire in a remote dip socket... i'll put it at the top outside of the ipc case, and have a plug in eeprom that i can easilly remove, alter some bytes and plug back in to see what happens... the plan is to compare a few dumps of different ipc's, and try to see what does what in the dump. 

I'll have my tech2 by then so i may be able to fix this with that... but im still interested in learning what in the eeprom file does what to the ipc. 


My meriva is a 1.3 (A13DTE) flip switch cruise, non stop/start... i am not sure if other vauxhall ipc's have the warning light for the rear flexdoors, where the auto wiper light is on other ipc's... tho i wonder where the auto wiper light goes on meriva ipc's.

My low level ipc also has a DRL on light below the right indicator light, but the uplevel one didnt have an led soldered on the pads there (nor to the shift light), i added the missing led's, but of course they dont light up... hard to trace the circuit without my magnifying lamp thing so see if resistors are missing.
