C1234 yaw rate sensor code after lift (2 Viewers)

[Mauser]

I just installed the Ironman 2.5" lift on my wifes 2005 GX470.

After aligning it I took it for a test drive and got the 2 VSC lights and the slip indicator. I went back and connected Techstream and I needed to do the zero point calibration. I erased the memory then went to the test mode and ran it. I no longer had the ZPC code, but now have a C1234 indicating that the yaw rate sensor is not functioning correctly. I have tried erasing the memory and also erasing the code, but it won't go away.

Could this code be caused by me stretching the abs/speed sensor wires? I don't know if I did or not. I tried not to.

Anybody have any ideas?

Thanks

Might be the ZPC is not complete. It have to be done at same time.

Its located in the center dash. So lift install would got nothing to do with it.

I didn't think the lift would have anything to do with it, but wasn't sure.

I just messed with it more and it seems to be working fine now.

When I originally tried to run the ZPC I did it with the TEMS fuse removed. I put the fuse back in and tried again and it didn't work. I took the fuse out again and still had the C1234 code, but also had another code that said my yaw sensor was no longer calibrated. I ran the ZPC again and everything is back to where it should be.
