Removal and Installation

WARNING:

•  Before servicing the SRS, turn ignition switch OFF, disconnect both battery terminals then wait at least three minutes.
•  Before disconnecting the air bag diagnosis sensor unit harness connectors, be sure to disconnect each harness connector of the side curtain air bag modules, front seat belt pre-tensioner, and front side air bag module, to prevent accidental air bag deployment by static electricity and seat belt pretensioner operation.
•  Do not use the air tools or electric tools for servicing.
•  When replacing the air bag diagnosis sensor unit, always check with the parts department for the latest parts information. Installing an incorrect air bag diagnosis sensor unit may or may not cause the air bag warning lamp to illuminate and may cause incorrect deployment of the supplemental air bags and seat belt pre-tensioners in a collision resulting in serious personal injury or death.

REMOVAL

1.  Always check the air bag diagnosis sensor unit ECU discriminated number (identification number) or part number using CONSULT.
2.  Disconnect negative and positive battery terminals, then wait at least three minutes. Refer to PG-77, "Removal and Installation".
