SRS Control Units and Sensors
SRS Unit, Front and Side Impact Sensors, and Roll Rate Sensor- Be careful not to bump or impact the SRS unit, front impact sensors, roll rate sensor, or side impact sensors when 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, roll rate sensor, or side impact sensors. The airbags could accidentally deploy and cause damage or injury.
- After a collision in which the front airbags or seat belt tensioners were deployed, replace the SRS unit, front impact sensors, and other related components. After a collision in which a side airbag deployed, replace the side impact sensor first on the deployed side, and the SRS unit. After a collision in which a side airbag and a side curtain airbag deployed, replace the side impact sensors first and second on the deployed side and the SRS unit. After a collision in which the airbags or the side airbags did not deploy, inspect for any damage or any deformation on the SRS unit, front impact sensors, roll rate sensor, and side impact sensors. Replace all damaged parts.
- Do not disassemble the SRS unit, front impact sensors, side impact 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, roll rate sensor, and side impact sensors 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 or the side impact sensors and roll rate sensor, and keep them away from dust.
- Store the SRS unit, front impact sensors, roll rate sensor, and side impact sensors in a cool (less than 104 degrees F/40 degrees C) and dry (less than 80 % relative humidity, no moisture) area.
