If I had a donor car...

[imac]

I'm having a helluva time diagnosing electrical issues in 99 s80 t6,

Hypothetically, if I had a donor car, what modules are vin specific and need to stay as a set?

Thanks

Every single CAN node basically.

So everything that ends in EM or CM. CEM, TCM, ECM etc etc.

Ok so the

CEM
TCM
ECM
REM
UEM
SRS

Are vin locked,

But not

ABS
ETM
AUM
PDM
DDM
PSM
CCM

Is this correct? Could my key be programmed to work with the immobilizer, or am I swapping ignition module as well?

This may be my easiest option, believe it or not
Thanks

What reason you want to swap all modules?

Did you try disconnect modules one by one from CAN bus?

[imac]

Yes, i have. But can something like a DDM take down the high speed network that ECM works on?

[yagger]

Through side ways only, like a power for example.

I found a 2005 s80 t6, mine is a 99. Does anybody know, electrically, what is different between a 99 and an 05?

[yagger]

It are very different cars.
