Yaw rate sensor is not communicating with the other modules. It is part of the stabilitrak system.

Do you know where the yaw rate sensor is and how to change it ???

Thanks,

Bill
It is under the carpet and the passenger seat.

The official instructions list the following:
  • Remove the passenger seat
  • Remove the door sill trim
  • Remove the hinge pillar trim
  • Remove the lock pillar trim
  • Remove the rear window panel trim
  • Remove the floor panel carpet
I haven't done it, but it seems like it has to be possible to get to it without that much disassembly.
Even cutting the carpet seems like a valid option, but again, I have not done it.

Thanks for the help !!!! It was exactly as JohnWR described....just under the passenger seat...simple plug and play...didn't even have to reset the code....went away all on its own ......
