Caution: Do not change the original position of the electronic control unit of the passive restraint system while the unit is connected to the power supply and the ignition is on. Otherwise, the airbag may deploy spontaneously, resulting in serious injury.
Caution: If the vehicle has been in an accident, the locations of the electronic control unit for the passive safety system and the impact sensors must be checked for deformation. In case of damage or excessive deformation, it is necessary to replace the body modules with the mounting locations of the electronic control unit of the safety system and impact sensors.
Caution: To prevent accidental airbag deployment, do not use any storage devices. Failure to follow this instruction may result in serious injury or death.
Note: Electronic control units are very sensitive to static discharge. Try not to touch the terminals of the electronic control unit connector.
Note: When installing a new passive restraint system control module, special programming equipment must be used.
Note: Repair of passive safety system components is not provided. In case of failure, the damaged element is replaced as an assembly.
Caution: Before starting any work, turn off the ignition and disconnect the negative battery terminal, then wait at least 90 seconds.
