I'm trying to fix this same issue with a 06' 350z 'rev-up' model.
It seems the rev-up model has a different abs/trc unit. It is a 84 pin module (Nissan part number: 47851-CF42A)
On this car pin 29 is a earth, so the wiring in the recommended fix won't work for the rev-up version.
I have tried and faild to find a pin out for this module, so any help would by hugely appreciated!
