Warning: Do not change the original position of the electronic control unit of the passive restraint system while the unit is connected to the network and the ignition is on. Otherwise, spontaneous deployment of the airbag may occur, which may result in serious injury.
Attention. If the vehicle has been in an accident, it is necessary to check the installation locations of the electronic control unit of the passive safety system and impact sensors for deformation. In case of damage or excessive deformation, it is necessary to replace the body modules with the installation locations of the electronic control unit of the safety system and impact sensors.
