Does anyone know how to find pin/security code in 2j74y dumpfrom 2002 cim module. There is no 93lc76 or other eprom, just 2x 2j74y mcu's
Thank you

If you have a CIM from the car as dash,it is easier to read the PIN from the dash.

This cim was taken from car and the vin reset but pin is lost but cim is in good working order but no pin to learn keys

read mcu's eeprom and let us see what is there ... maybe will find one solution for U.

Here are dumps from another cim's mcu's, the code from this unit is 2750 but where is it in the dump, or how can it be calculated

Can anyone help with finding or calculating pin from 2j74y files in
previous post ?
Thanks
