SRS Unit, Front and Side Impact Sensors, Driver's Seat Position Sensor and Front Passenger's Weight Sensors
NOTE:
Some systems store data in memory that is lost when the 12 volt battery is disconnected. Before disconnecting the 12 volt battery, refer to 12 volt Battery Terminal Disconnection and Reconnection (see
12 VOLT BATTERY TERMINAL DISCONNECTION AND RECONNECTION
).
- Turn the ignition switch to LOCK (0), disconnect the negative cable from the 12 volt battery, then wait at least 3 minutes before starting installation or replacement of the SRS unit or disconnecting the connectors from the SRS unit.
- Be careful not to bump or impact the SRS unit, the front impact sensors or the side impact sensors when the ignition switch is in ON (II), or for at least 3 minutes after the ignition switch is turned to LOCK (0).
- Do not reconnect any connectors to the SRS control unit until it is fully installed, including torquing the bolts.
- During installation or replacement, be careful not to bump (by impact wrench, hammer, etc.) the area around the SRS unit, the front impact sensors or the side impact sensors. The airbags could accidentally deploy and cause damage or injury.
- After a collision where the front airbags, the side airbags, the side curtain airbags, or the seat belt tensioners deploy, go to COMPONENT REPLACEMENT/INSPECTION AFTER DEPLOYMENT . After a collision where the airbags or the side airbags do not deploy, inspect for any damage or any deformation on the SRS unit, the front impact sensors and the side impact sensors. Also, do the active head restraint inspection (see ACTIVE HEAD RESTRAINT INSPECTION ). Replace all damaged parts.
- Do not disassemble the SRS unit, the front impact sensors, the side impact sensors, the driver's seat position sensor or the front passenger's weight sensors.
- Always install the SRS unit and all impact sensors securely with new TORX bolts torqued to the specified torque.
- Do not spill water or oil on the SRS unit or any of the sensors.
