Hi All,

I am looking for the SKC in my cluster - 1999 Jetta GLX with 1J0 920 900J cluster. Immo 2 I believe.  I've read out the 93C66 serial eeprom but don't see anything like I've seen here in other cluster eeprom dumps.  It just looks scrambled - maybe with a bit stuck off.  Would you guys mind taking a look at this file and provide some comments?  Does this look messed up?  Do you see a SKC in there anywhere?

Thanks,

Bill

My Immo box is a little different,  I'm thinking it's the next gen version of the one you linked me to. It's got a Motorola micro - probably a customized version of the 68hc05  and no separate eeprom.  The module at the top left contains a Phillips UAA3201 RF receiver inside that tin can - most likely for the fob.

I'm striking out here - The EEPROM on the ECU has FFFF in the SKC field.  No SKC found in the cluster,  and not much I can get out of the Immo box.

Before I started ripping into the hardware I spent a long time trying to get the drivers to work but never managed to get any of the software to recognize the cable I bought - even though it has the recommended FDDI serial-usb chip in it.  Don't know if it's something weird with my old Dell Latitude Win XP setup or what.  Maybe I'll try buying yet another cable.

Thanks again for your input.

Bill

it is in immo box, probably 24c04

immo 2 doesnt store skc in ecu, as is obvious from its design
