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.

Is this something the arduino can handle?

dataseet And if so how would I go about doing this? Writing to the eeprom isn’t too hard if you have access to the pins. But what is the format of the data? No clue how do I go about getting this info? 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.

Is there a connector next to this chip which does this? I’ll see if I can find my old bitbasher – but given the datasheet you could figure it out.

Given that it’s ‘in-circuit’- I presume soldered – you’ll 935c6 need to break the leads to CS, SK ,DI DO, so as to prevent the existing curcuitry from preventing your operations.

But not that easy.

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! It may be cheaper and less risky to go to a Cherokee dealer and get him 93c566 do it Well the good news is its a late model and I have everything I need from a junkyard for very cheap.

Ill see what I can do about separating that chip. If I do go about pulling the code, is there a circuit 93×56 needs setup and any pre written code for this?

Hi, What do the professionals do when they need to change instrument cluster? There must be a procedure to clone the new cluster from the old.

Everything runs on smoke, let the smoke out, it stops running I actually did do some googling and most people either take it to the dealership or reflash it with an EEPROM flasher. I just figured why not try with my arduino and learn a thing or two. Not to mention so many people in the jeep community have arduinos and would benefit from this.

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