Title: How do I find funcs in assembly that set a specific DTC?
Post by: elRey on October 18, 2012, 07:01:02 PM
Use you have the DTC location and index via http://nefariousmotorsports.com/forum/index.php?topic=567.0

How do you go about identifying all teh functions in assembly that set/clear that DTC?

i.e. 17964/P1556 - Charge Pressure Control: Negative Deviation -> find function that set it

Thanks,
Rey

Just saw this thread...

The DTC index is passed to the function via r12, so it is easily found by searching.
