WARNING:
Always observe the following items for preventing accidental activation.
• Before servicing, turn ignition switch OFF, disconnect battery negative terminal and wait for 3 min-
utes or more.
• Before disconnecting the air bag sensor unit harness connector, be sure to disconnect each har-
ness connector of the air bag module and pre-tensioner seat belt to prevent air bag deployment by
static electricity and pre-tensioner seat belt operation.
• Never use air tools or electric tools for servicing.
• When replacing the air bag diagnosis sensor unit, always check with the parts department for the lat-
est 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.
