Air Bag System-Component Reuse

Component Reuse
Even if an air bag module or pretensioner seat belt does not deploy in a collision and does not have any external signs of damage, it may have been damaged internally, which may cause improper operation. Improper operation may cause serious injury. Always self-check the undamaged air bag module or pretensioner seat belt to determine whether it can be reused.

Restraint Control Module RCM
For vehicles with a single point sensor, once an air bag module is deployed due to an accident or other causes, the RCM must be replaced with a new one even if the used one does not have any external signs of damage. The used RCM may have been damages internally which may cause improper operation, resulting in major injuries or even death. The used single point RCM cannot be bench-checked or self-checked.

The restraint control module (RCM) orientation is critical for correct system operation. If a vehicle equipped with an air bag supplemental restraint system (SRS) has been involved in a collision in which the center tunnel area has been damaged, inspect the mounting and bracket for deformation. If damaged, the RCM must be replaced whether or not the air bags have deployed. In addition, make sure the area of the RCM mounting is restored to its original condition

Side Air Bag Sensor
Because a sensor is built into the side air bag sensor, when the side air bag module operates (deploys), there may be a problem, such as an internal malfunction, even if there is not any external damage or deformation. If the side air bag sensor is reused, the side air bag module may fail to operate normally and cause a serious injury. Always replace the side air bag sensor with a new part. The side air bag sensor cannot be bench- checked or self-checked.
