SRS Control Units and Sensors

SRS Unit, Front and Side Impact Sensors, Driver's Seat Position Sensor, Front Passenger's Weight Sensor unit. Front Passenger's Weight Sensors and Roll Rate Sensor

- Be careful not to bump or impact the SRS unit, front impact sensors, side impact sensors, or roll rate sensor whenever the ignition switch is ON (II), or for at least 3 minutes after the ignition switch is turned OFF.




- During installation or replacement, be careful not to bump (by impact wrench, hammer, etc.) the area around the SRS unit, front impact sensors, the side impact sensors, or roll rate sensor. The airbags could accidentally deploy and cause damage or injury.
- After a collision that caused any airbag to deploy, the SRS unit and many other components must be replaced.
- After a collision, calibrate the front passenger's weight sensors. If the sensors cannot be calibrated, replace them.
- Do not disassemble the SRS unit, front impact sensors, side impact sensors, driver's seat position sensor, front passenger's weight sensor unit, front passenger's weight sensors, or roll rate sensor.
- Turn the ignition switch OFF, disconnect the battery negative cable and wait at least 3 minutes before beginning installation or replacement of the SRS unit, or disconnecting the connectors from the SRS unit.
- Be sure the SRS unit, front impact sensors, side impact sensors, and roll rate sensor are installed securely with the mounting bolts torqued to 9.8 N.m (1.0 kgf.m, 7.2 lbf.ft).
- Do not spill water or oil on the SRS unit, the side impact sensors or roll rate sensor, and keep them away from dust.
- Store the SRS unit, front impact sensors, side impact sensors, and roll rate sensor in a cool (less than 104 °F/40 °C) and dry (less than 80 % relative humidity, no moisture) area.
