Precautions for Handling and Storage of Air Bag System Components
Precautions for Handling and Storage of Air Bag System Components
WARNING:
Measuring the resistance of any air bag (inflator) module (driver, passenger, side or curtain module) or any seat belt pretensioner (driver or passenger pretensioner) with a tester is dangerous, as the electric current from the tester may trigger the air bag or pretensioner.
Never attempt to measure the resistance of an air bag (inflator) module or seat belt pretensioner.
When checking each wiring harness, use special tool (A) referring to Use of Special Tools Use of Special Tools.

SDM
WARNING:
- If the SDM is not rigidly attached to the vehicle, it could accidentally cause the air bags to deploy when the air bag system is powered, possibly causing personal injury.
Always make sure that the SDM is rigidly attached to the vehicle before supplying power to the air bag system.
- The SDM that has been involved in an accident severe enough to cause deployment of air bags is not guaranteed to provide its original performance.
Never use an SDM that has been involved in an air bag deployment accident. Refer to Air Bag Diagnostic System Check Air Bag Diagnostic System Check
Air Bag for the SDM check procedure.
- Never attempt disassembly of SDM
- When storing SDM, select a place where neither high temperature nor high humidity is anticipated and oil, water and dust are kept off.
- If SDM has been dropped, replace it with a new one.
- If SDM installation part of floor is damaged, repair it completely before reinstallation.
- All SDM and mounting bracket fasteners must be carefully torqued and the arrow on SDM must be pointed toward the front of the vehicle to ensure proper operation of the air bag system.
Live (Undeployed) Air Bag (Inflator) Modules
Special care is necessary when handling and storing a live (undeployed) air bag (inflator) modules. Accidental deployment of air bag (inflator) module could throw itself or objects around it in the air.
WARNING:
Failure to take proper precautions when handling and storing a live (non-deployed) air bag (inflator) module can result in personal injury due to accidental deployment of the air bag.
- Handle or store a live air bag (inflator) module in a place with an ambient temperature below 65 °C (150 °F), without high humidity and away from electric noise sources.
- Always carry a live air bag (inflator) module with the air bag's opening pointed away from you. Doing so will help reduce the chance of injury in case of accidental deployment of the air bag.
- Never carry a live air bag (inflator) module holding by the wires or connector on its underside.
- Always place a live air bag (inflator) module on a bench or other surface with the bag (trim cover) side facing up.
- Do not place anything, including another (inflator) module, on top of an air bag (inflator) module. Allowing for a free space above the module is essential to minimize the risk of personal injury in the event of accidental deployment of the air bag (inflator) module.
Live (Inactivated) Seat Belt Pretensioner
WARNING:
Failure to take proper precautions when handling and storing a live (non-activated) seat belt pretensioner can result in personal injury due to accidental activation of the pretensioner.
- Handle and store a live seat belt pretensioner in a place with an ambient temperature below 65 °C (150 °F), without high humidity and away from electric noise sources.
- Never carry a live seat belt pretensioner by holding the belt webbing.
- When placing a live seat belt pretensioner on a workbench or other flat surface, make sure that the pretensioner's exhaust hole (1) side faces upward.
- Do not put anything on the exhaust hole (1) side of a live seat belt pretensioner. Also avoid placing one live seat belt pretensioner on top of another.
Special care is necessary when handling and storing a live (inactivated) pretensioner. Accidental activation of pretensioner will cause high pressure gas to blow off from the exhaust hole and retract the webbing (1) quickly into the retractor assembly (2). These actions may throw the pretensioner itself or objects around it in the air.
Deployed Air Bag (Inflator) Module and Activated Seat Belt Pretensioner

Air Bag Wire Harness and Connector
Air bag wire harness includes in main harness (1), instrument panel harness (2) and floor harness (3). Air bag wire harness can be identified easily as the connector side wire harness is covered with a yellow protection tube or tape. Be careful when handling it.
- If damaged harness, connector or terminal is found on an air bag wire harness, replace the harness.
- When installing the air bag wire harness, be careful so that it is not caught or does not interfere with other parts.
- Make sure air bag system grounding point (4) is clean and ground terminal is securely fastened for optimum metal-to-metal contact. Poor grounding can cause intermittent problems that are difficult to diagnose.
