Not to mention so many people in the jeep community have arduinos and would benefit from this.
If I do go about pulling the code, is there a circuit that needs setup and any pre written code for this? I actually did do some googling dtaasheet most people either take it to the dealership or reflash it with an EEPROM flasher.

I know this guy here did it with an off the shelf programmer, which is quite expensive compared to the datasjeet I all ready own. Given that it’s ‘in-circuit’- I presume soldered – you’ll probably need to break the leads to CS, SK ,DI DO, so as to prevent the existing curcuitry from preventing your operations.
Is this something the arduino can handle? I’ll 933c56 into that cloning. But not that easy. There must be a procedure to clone the new cluster from the old.
Writing to the eeprom isn’t too hard if you have access to the pins. Just as the title states I wish to flash a 93c56 EEPROM in my jeep cherokee gauge cluster because my old gauge cluster has malfunctioned and the new one will have incorrect millage on the odometer. But what is the format of the data?

I just wonder if moving the chip might be a solution. And if so how would I go about doing this? I’ll see if I can find my old bitbasher – datsaheet given the datasheet you could figure it out.
Well the good news is its a late model and I have everything I need from a junkyard for very cheap. If datashee had the appropriate sw from the manufacturer I bet you could do this via the OBDII connector – but I also bet they’re not telling you how! Is there a connector next to this chip which does this?
TomGeorge Design and Repair of industrial control systems. No clue how do I go about getting this info?

It may be cheaper and less risky to go to a Cherokee dealer and get him to do it Everything runs on smoke, let the smoke out, it stops running Ill see what I can do about separating that chip.
It won’t be easy, as they don’t want crooks ‘clocking’ the mileage. I just figured why not try with my arduino and learn a thing or two.
Hi, What do the professionals do when they need to change instrument cluster?
