Air Bag System Service Warnings




Component Disassembly
^ Disassembling and reassembling the components of the air bag system 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 components.





Wiring Harness Repair
^ Incorrectly repairing an air bag system wiring harness can accidently deploy the air bag module, which can 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
^ Inspection the air bag module by using an ohmmeter can deploy the air bag module, which can 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 accidently 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 accidently deploys.

SAS Unit Handling:




SAS Unit Handling
^ Installing a connected SAS unit is dangerous. Movement generated during installation can cause the crash sensor inside the unit 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 unit, firmly mount the unit to the vehicle.

^ Disconnecting the SAS unit connector or removing the SAS unit with the ignition switch at ON can cause the air bag modules to deploy, which may seriously injure you. Before disconnecting the SAS unit connector or removing the SAS unit, turn the ignition switch to LOCK, then disconnect the negative battery cable and wait for more than I minute to allow the backup power supply of the SAS unit to deplete its stored power.
^ Once an air bag deployed due to an accident or other causes, the SAS unit must be replaced with a new one even if the used one does not have any external signs of damage. The used SAS unit may have been damaged internally which may cause it not to operate properly, resulting in major injuries or even death. The used single point SAS unit cannot be bench checked or selfchecked.
