Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
System Components: Combox: Notes
The Combox control unit is located in a housing that has been designed for installation without a holder. Thus in certain vehicles, the Combox is installed without an additional sheet metal holder.
In the event of a collision, however, the impact energy is transmitted directly to the control unit when there is no sheet metal holder. Therefore the Combox control unit must be checked for external damage after the vehicle has been in a collision.
