Crash Zone Sensor Handling
- Handing the air bag module before allowing the back-up power supply of the SAS control module to deplete its stored power can accidentally operate (deploy) the air bag, pretensioner seat belt, and lap pretensioner seat belt, which may cause serious injury.
- Removing the crash zone sensor or disconnecting the crash zone sensor connector with the ignition ON can activate the crash zone sensor and operate (deploy) the air bags, pretensioner seat belts and lap pretensioner seat belts which may cause serious injury. Before removing the crash zone sensor or disconnecting the crash zone sensor connector, always switch the ignition off, disconnect the negative battery cable, and then wait for 1 min or more to allow the backup power supply of the SAS control module to deplete its stored power.
- If the crash zone sensor is subjected to shock or the sensor is disassembled, the air bags, pretensioner seat belts and lap pretensioner seat belts may accidentally operate (deploy) and cause injury, or the system may fail to operate normally and cause a serious accident. Do not subject the crash zone sensor to shock or disassemble the sensor.
- Because a sensor is built into the crash zone sensor, once the air bags, pretensioner seat belts and lap pretensioner seat belts have operated (deployed) due to a collision or other causes, the crash zone sensor must be replaced with a new one even if the used one does not have any visible external damage or deformation. If the crash zone sensor is reused, the air bags, pretensioner seat belts and lap pretensioner seat belts may not operate (deploy) normally, which could result in a serious accident. Always replace the crash zone sensor with a new one. The crash zone sensor cannot be bench-checked or self-checked.
