Air Bag(s) Arming and Disarming: Service Precautions

Component Disassembly
Disassembling and reassembling air bag system components can render the system inoperative which may result in serious injury or death in the event of an accident. Do not disassemble any air bag system component.





Wiring Harness Repair
Incorrectly repairing an air bag system wiring harness can accidentally deploy the air bag module which may cause serious injury. If a problem is found in the system wiring, replace the wiring harness. Do not try to repair it.





Air Bag Module Inspection
Inspecting the air bag module by using an ohmmeter can deploy the air bag module which may cause serious injury. Do not use an ohmmeter to inspect the air bag module.





Air Bag Module Handling
A live (undeployed) air bag module may accidentally deploy when it is handled and cause serious injury. When carrying a live air bag module, point the front surface away from your body to lessen the chance of injury In case it deploys.





A live air bag module placed face down on a surface is dangerous. If the air bag module deploys, the motion of the module can cause serious injury. Always face the front surface up to reduce the motion of the module in case it accidentally deploys.

Side Air Bag Module Handling
When the side air bag module deploys due to a collision, the interior or the seat back (pad, frame, etc.) may become damaged. If the seat back is reused and the side air bag module does not deploy properly, a serious accident may result. When the side air bag module deploys, always replace both the side air bag module and seat back (pad, frame, trim) with new parts. After preparation and also when the side air bag module is deployed in the vehicle using SSTs (Deployment tool and Adapter harness), confirm that the seat operates normally and that the harness is positioned properly.

SAS Control Module Handling
Installing a connected SAS control module is dangerous. Movement generated during installation can cause the crash sensor inside the control module to send an electrical signal to the air bag modules. This will deploy the air bag modules, which may result in serious injury. Therefore, before connecting the SAS control module, firmly mount the control module to the vehicle.
Disconnecting the SAS control module connector or removing the SAS control module with the ignition switch ON can cause the air bag modules to deploy, which may seriously injure you. Before disconnecting the SAS control module connector or removing the SAS control module, turn the ignition switch to LOCK, then disconnect the negative battery cable and wait for more than 1 minute to allow the backup power supply of the SAS control module to deplete its stored power.
Once an air bag is deployed due to an accident or other causes, the SAS control module must be replaced with a new one even if the used one does not have any external signs of damage. The used SAS control module may have been damaged internally which may cause improper operation, resulting in major injuries or even death. The used SAS control module cannot be bench-checked or self-checked.

Side Air Bag Sensor Handling
Disconnecting the side air bag sensor connector or removing the side air bag sensor with the ignition switch at ON position can cause the side air bag sensor to operate and the side air bag module to deploy, which may seriously injure you. Before disconnecting the side air bag sensor connector or removing the side air bag sensor, always turn the ignition switch to LOCK position ,then disconnect the negative battery cable and wait for more than 1 minute to allow the backup power supply of the SAS control module to deplete its stored power.
If the side air bag sensor is subjected to shock or the sensor is disassembled, the side air bag module may operate (deploy) suddenly and cause injury, or it may fail to operate normally and cause a serious accident. Do not subject the side air bag sensor to shock or disassemble the 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 one. The side air bag sensor cannot be bench-checked or self-checked.
