SLO_350Z

So about three years ago I bought my 2003 350z. When I bought it, it had it welded differential and just recently I bought a used Nismo differential in an oem diff case. I put new bushings in it and put it in my car and took out my welded. From my previous knowledge, I knew that the gravity sensor or yaw under the center consul was disconnected and the other part behind it too it disconnected. The pink L shaped fuse for ABS and VDC had the one side ripped out. so after installing my differential, I reconnected everything under the center consul put in a new fuse it to work with ABS and VDC. It tuned on and all the lights were gone. So I went down my street and a few hundred feet later all my lights came back on which were ABS, Slip, VDC and the E brake light even though the E brake was off. It’s also important to mention that my front right wheel/brake a few times at low speeds breaking on its own ABS style with the on off on off really quickly. I ran my OBD2 and this is what I got:P1211

Traction Control System Control Unit Function

C1143 N/A

Steering Angle Sensor System

C1109 N/A

Vehicle Battery Voltage Abnormal

C1142 N/A

Pressure Sensor System

C1115 N/A

ABS Sensor Abnormal Signal

C1145 N/A

Yaw Rate Sensor System


so then I bought a new battery since my old one was from 2018, and it got rid of the yaw rate sensor code but all the others stayed the same even the battery. Then I bought brand new ABS speed sensors, front and rear and install them all. This did not changed to anything. I don’t know what to do and I just want my VDC and ABS to work any thoughts. I’ll put pictures of screen shots of all the error codes I got trough this whole thing.

The steering angle sensor issue sounds like the clock spring is broken or out of calibration. It looks like you purchased a converted drift vehicle and want to convert it closer to stock again. This could prove challenging as the previous owner could have cut/modified the wiring harness to disable a lot of the safety systems related to VDC/ABS. The yaw sensor being disconnected is a common modification.

The abnormal battery voltage could be related to a failing alternator or poor chassis grounds. But also damaged/cut wiring.

I would fix the steering angle issue 1st (new clock spring), as the other codes could be related to this. Then go from there.
Good Luck!

Check them battery terminals that they are tight or for corrosion. I agree with Icer about replacing the clock spring. Chances are the stock steering wheel was replaced with an aftermarket one at some point and they damaged the clock spring. Good luck

I will buy this https://www.carparts.com/air-bag-clo...dard/sicbs1963 and install it, I did put in an aftermarket steering wheel and I could have broke it. All Battery points are clean and nothing appears to be cut on the wiring harness. I will keep y'all posted thank you so much.

If it was me I would try a used one first. Yea you dont really know the condition of it but before I spend $168 for one Ill slap a used one on first and if it work all gravy.
