How To Change Eprom Pin Code And Vin Number In Gm S Instrument Cluster Click "reprogramming" and click "write fgstnr". enter the last 7 of your vin. plug it into the car and turn the key to position 2 to download the mileage. final coding: after restoring eeprom and setting vin and mileage, you'll need to code the cluster to your car. Hey guys, i know several people have been asking me if i can help them to reset the mileage on a used cluster in order to allow it to match their car's actual vin, mileage, and coding, just like buying a brand new uncoded cluster from the dealer or other parts websites, so i have decided to provide the instructions on how to do it.

How To Change Eprom Pin Code And Vin Number In Gm S Instrument Cluster Gm 8 digit part number for cluster is stored in hex format msb→lsb cluster model id is 4 large characters from the label. also stored as ascii plain text. trip meter value is in speedometer pulses, e.g. miles = value 4000, it is stored lsb→msb. took me a while to figure out how they were encoding this, but it means that your trip meter is. Re: ve instrument cluster eeprom programming. by zerone » tue sep 13, 2011 10:26 pm. to swap instrument clusters on a ve commodore, it is recommended to obtain the above eeprom locations from the working cluster fitted to the vehicle, (odo reading, vin number, and vehicle options located at 0x0142 0x0143, as well as 0x0337 to 0x033f and 0x0346. Reading writing bcm's the bcm uses an atmel 24c04n eeprom. the eeprom address pins are hardwired in the bcm so that pin a1 is tied to vcc and a2 is tied to ground. because of this, there is a specific soic8 pin wiring you must use, and a specific external addressing schema you must use in the revelprog is program. click on the select device icon. The eeprom is a 256 byte chip, on mine it configured 256 for chip size, 8 for page, and 95xx for commands. a quick note, sometime around 2005 gm switched the location of u15 and u16, on the later clusters the eeprom is in the location next to the prndl display instead of off to the side where it is on mine. for the newer ones you have to gently.

I was able to get the pin out of the new cluster, but i need to somehow obtain the original pin in order to adapt the new cluster via vcds instruments (17) adaptation (050) to set it up with the original pin. i am able to physically change the code of the new cluster to match immo id and vin appearing in the ecu, but that is not enough to allow. Once the board is disassembled, we look for a 8 pin eeprom memory chip on the back of the board and there we connect our memory reader, and we read the data. the first line contains the vin. just replace the number with your car and iits ready to go. i did not change anything else but that number.
