Re: Problem with MCU P062F

Did you try the RL78 method? i think there are several examples of both the VIN and the Part Number sequence with the check sum in this thread on the first page. Hi, I spent some time trying various parameters, but was not able to calculate the CRC or find the algorithm. The algorithm can be anythi...

yes, after replacement AD8677 the car started up
but not for long.
As I understand it, the problem is in the capacitors, which, after heating, give an error again

Re: Problem with MCU P062F

There are members who have discussed programming the VIN in the P1A15 threads started by Lic and Gencis who may be able to give you some advice. Did you remove the eeprom when reading and programming, or try to do it while still on the board? What voltage did you use for Vcc and for the serial line...

Re: Problemwith MCU P062F

So comparing the eeprom data between the two MCU--in all the other addresses with the random/unknown values other than the VIN and SERIAL Number, Are they identical? there are differences in multiple lines but there is an opportunity to somehow reprogram the immobilizer in order to install a second...

Re: Problemwith MCU P062F

Thank you for the answers and for posting the full eeprom contents. It appears to be other data stored which we do not know the purpose, or if it is corrupted or correct. But we need to figure out how to calculate the correct check sum for your VIN. I took as a basis the second MCU with unchanged e...

Re: Problem with MCU P062F

To help understanding, please confirm or correct the following: 1. Your car is a 2012 Mitsubishi iMiev with VIN# JMBLDHA3WCU00610 ? 2. When you got the car it came with an MCU from a 2011 Peugeot iOn (VIN ..801988) with MCU serial# CF1101004920 ? 3. In the 24C64 eeprom, the VIN and Serial Number ar...

Re: Problemwith MCU P062F

If you look at the label on the MCU, there will be a part number and serial number. 9499A620 is a Mitsubishi part number for the MCU, and the C... number is the serial number. i suspect that those must also match in the eeprom in addition to the VIN; also if these are changed then the checksum will...
