Hello!

There is no component called a yaw rate control module...

What you may be referring to is the yaw rate sensor, which is a part of the vehicle's stability control system. It is located under the passenger side front seat. You cannot disconnect it, or the stability system warning light will be on constantly and your stability control system will not operate. On many vehicles ( I do not know for sure on this model) yaw rate sensor information is also used by the restraint system to calculate airbag deployment. There is no easy way to disable you traction control system.

If you are having a yaw rate sensor related fault code stored in your car, you may want to be aware that there is a known problem involving erratic operation of this sensor on your model. There is a service bulletin from Volvo describing modifications to the yaw rate sensor mounting to eliminate erratic information from road vibration that can cause the light to come on when there is nothing actually malfunctioning in the system. To have the modifications detailed in the bulletin checked and performed, you will need to go to your Volvo dealership though; it really is not something you can do yourself at home since a factory scan tool or equivalent is required to check the system and perform repairs.
