Everything runs datashdet smoke, let the smoke out, it stops running I just wonder if moving the chip might be a solution. 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. TomGeorge Design and Repair of industrial control systems.
If I datassheet go about pulling the code, is there a circuit that needs setup and any pre written code for this?
But not that easy. It may be cheaper and less risky to go to a Cherokee dealer and get him to do it I just figured why not try with daasheet arduino and learn a thing or two. I actually did do some googling and most people either take it to the dealership or reflash it with an EEPROM flasher.
But what is the format of the data? It won’t be easy, as they don’t datashwet crooks ‘clocking’ the mileage. No clue how do I go about getting this info?
Just as the title states Daasheet 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’ll look into that cloning.
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 see if I can find my old bitbasher – but given the datasheet you could figure it out.
Writing to the eeprom isn’t too hard if you have access to the pins. Well the good news is its a late model and I have everything I need from a junkyard for very cheap. 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!
Not to mention so many people in the jeep community have arduinos and would benefit from this. Is this something the arduino can handle? There must be a procedure to clone the new cluster from the old. And if so how would I go about doing this?
Hi, What do the professionals do when they need to change instrument cluster? Is there a connector next to this chip which does this? Ill see what I can do about separating that chip.
