WARNING:
• Before servicing, turn ignition switch OFF, disconnect battery negative terminal and wait 3 minutes
or more.
• Before disconnecting the air bag sensor unit harness connector, be sure to disconnect the each har-
ness connector of the air bag module and the pre-tensioner seat belt to prevent air bag deployment
