Jeep 2001 SKIM with OJ66D - should be easy

[obdsystems]

Can't read this chip so think dead.

read before off old Golfs with 2M crystal with no probs so should be easy..
but this time have same socket (yeah cpu removed from PCB) but with 4M crystal as original PCB.



Otherwise any other advice guys/chat on this wet sunday?
Cheers


EDIT: Will retry, but does anybody know if only VIN matched ?
ie I can get another chip & image so do repair -

Yes you can get another chip just read without removing it using UPA, edit the vin and program a key. You're good to go.

As above... dont forget these often fail because the MCU is dead.

[teuton]

Yes, just & only VIN matched

Note on pins 58 and 59 have a 4Mhz crystal (not shown here!).
All the other pins are as diagram. a QFP64 adaptor would of been supplied with your xprog. i prefer to use this adaptor than incircuit :)
(when i do right lol)
