Hey guys,
I have a 2007 Nissan 350z Touring (Manuel) that has been having some ABS issues for some time and I need some assistance taking care of this NIGHTMARE.
1.)I have on my instrument cluster the ABS, VDC,TCS, and BRAKE lamp all on constantly
2.) I Scanned the car and have ABS code C1148
3.) I just straight up replaced the wheel speed sensor after checking for continuity and the wheel speed sensor didn't have continuity- This did not fix the issue
4.) I checked the wheel for play and noticed the lower ball joint was wiggling so I replaced it - This did not fix the issue
5.) I checked the harness wiring connector from the wheel speed sensor to the ABS Brain Next to the passenger footrest area for continuity, there was continuity, however I tapped the pin and not the wire, tell me if I should re do this?
6.) I bleeded the brakes on all 4 tires - This did not fix the issue
7.) I replaced the whole wheel hub on all 4 tires- This did not fix the issue
8.) I replaced the connecter from the harness to the wheel speed sensor because it just seemed like the original connector was getting shredded and running a live diagnostic reading was giving me weird readings as if the speed was taking more time to load on the front wheels than the rear ones. once I replaced the connector I got better readings- This did not fix the issue
9.) i disconnected the battery terminals for about a month, reconnected the battery terminals and fired up the car, THE LIGHTS WHERE GONE. but before i got to excited, after idling and warming up the car, the LIGHTS CMAE BACK ON. same C1148 and VDC, TCS, ABS, BRAKE lamp all on
10) i got a wheel alignment of course about 3 times after doing work to the hubs and lower ball joint - This did not fix the issue

can anyone point me into the rite direction? this seems like an electrical issue and not a component issue?
not 100 percent sure if I'm having some kind of alternator issue with power distribution? I have no idea I'm lost in the sauce on this one.

 

New update:

I went ahead and disconnected the wheel speed harness to the front right wheel speed sensor and began to cut away the shielding. I've gotten as far back as the battery and I still see no physical damage to the harness. Im getting to the point of no retrun which is the fire wall, I stopped there. I went to the passenger side kick panel where the abs/vdc/tcs co trol unit is at. I found both wires that are supposed to be the front right wheel speed connects (red/black and green/black) and started cutting away at that to trace the wire back. Im noticing this same wire is connected to another connector. This has got me at a stopping point since I've lost sight of how this wire is actually connected and not knowing if it's connected anywhere eles.

Looking through a wiring diagram, the wire does not co nect to other components besides the control unit. Is it safe to say running one whole new wire to the wheel speed sensor is not a bad idea? Or will this cause more issues with the abs system?
