There must be a procedure to clone the new cluster from the old. Well the good news is its a late model and I have everything I need from a junkyard for very cheap. If I do go about pulling the code, is there a circuit that needs setup and any pre written code for this? No clue how do I go about getting this info? Ill see what I can do about separating that chip.

It won’t be easy, as they don’t want crooks ‘clocking’ the mileage. 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. I know this guy here did it with an off the shelf programmer, which is quite expensive compared to the arduino I all ready own.

Not to mention so many people in the jeep community have arduinos and would benefit from this.

But what is the format of the data? Writing to the eeprom isn’t too hard if you have access to the pins.

Hi, What do the professionals do when they need to change instrument cluster? 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.

I’ll look into that cloning. I just wonder if moving the chip might be a solution.

I’ll see if I can find my old bitbasher – but given the datasheet you could figure it out. If you 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!

I just figured why not try with my arduino and learn a thing or two. And if so how would I go about doing this?

But not that easy. I actually did do some googling and most people either take it to the dealership or reflash it with an EEPROM flasher. Is there a connector next to this chip which does this?
