Nissan Skyline GT-R R32 Attesa codes



Some people like to spell it Attessa. All Nissan's technical information writes it with two T's and one S. I misspelled it for years. Not like I don't' misspell a few words. Attesa is the name of Nissans all wheel drive system that they used in the R32 - R35 Nissan Skyline GT-R/ GT-R . The R32 , R33, and R34 systems are functionally similar. They use a electric powered hydraulic pump to provide ATF to the transfer case to lockup the center differential. The more pressure the system places on the center differential, the more it locks up the center differential. The more the center diff locks up , the more power that goes to the front wheels. The amount of center diff lockup is controlled from inputs from the ATTESA ECU. The ATTESA ECU gets its inputs from the engine ECU, ABS sensors , and a G-sensor.
