i have a 2005 g35 coupe with currently 29,000 miles and i have had this problem for 6 months now. 4 months after i bought this car, i noticed my brakes starting to pulsate at somewhat high speeds. Then the lights would come on Vdc off, slip and abs, then the braking would be normal but those lights on. i have extended warranty so i went to the dealer and they replaced a wheel sensor, i took it out, same problem. Went back and they changed the g sensor or yaw rate sensor, same problem. Went back and they changed the ABS module, same problem. Then went back and they did an ABS calibration, same problem. To this day those lights still come on and the diagnostics say all sensors are working. i recently also got new tires and i got an alignment done which shows have an issue with a negative camber and a local mod shop says i might have a wheel bearing problem or an electrowheel or something. keep in mind this went to a dealer so brake fluid, battery resets and all that is all been done and still not fixed. The rotors and pads are also fairly new and fine. Someone please help with this problem.

 

I had to replace both the speed sensors and abs sensors in order to get mine to go away. though they were only off for about a month before my car was totalled. so not sure if it's a permanent fix

 

But my sensors are working properly they even diagnosed them
