It's getting common problem for early model R35GTR, problem again(+_+)''' yes.
This time ABS unit!!!
Unfortunately need to replace whole ABS unit from NISSAN genuine parts, of cause cost will be $$$ . especially for parallel import vehicle.
After replace we need: steering angle sensor adjustment, G sensor calibration, press sensor calibration, and valve calibrations to clear the fault code. (*_*)''''' too many trouble this car......And we have another one with center screen problem......more$$$
