SRS Unit, Front and Side Impact Sensors, Rear Safing Sensor, Driver's Seat Position Sensor, and Front Passenger's Weight Sensors
WARNING: This page is about a different car, the 2013 Acura MDX, 2012 Acura MDX, 2011 Acura MDX, and 2010 Acura MDX. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Some systems store data in memory that is lost when the battery is disconnected. Before disconnecting the battery, refer to Battery Terminal Disconnection and Reconnection (see
USING THE GR8 BATTERY DIAGNOSTIC STATION
).
- Turn the ignition switch to LOCK (0), disconnect the negative cable from the battery, then wait at least 3 minutes before beginning 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, the side impact sensors, or the rear safing sensor when the ignition switch is in ON (II), or for at least 3 minutes after the ignition switch is turned to LOCK (0).
- During installation or replacement, be careful not to bump (by impact wrench, hammer, etc.) the area around the SRS unit, the front impact sensors, the side impact sensors, or the rear safing sensor. The airbags could accidentally deploy and cause damage or injury.
- After a collision where the front airbag, the side curtain airbags, or the seat belt tensioner deployed, 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, the side impact sensors, and the rear safing sensor. Also, do the front seat active head restraint inspection (see FRONT SEAT ACTIVE HEAD RESTRAINT INSPECTION ). Replace all damaged parts.
- Do not disassemble the SRS unit, the front impact sensors, the side impact sensors, the rear safing sensor, the driver's seat position sensor, or the front passenger's weight sensors.
- Always install the SRS unit, all impact sensors and the rear safing sensor securely with new TORX 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 any of the sensors.
