REMOVAL SERVICE POINTS
DISCONNECTION
Turn the ignition key to the "LOCK" position, disconnect the
negative battery cable from the battery and tape the terminal.
Caution
Wait at least 60 seconds after disconnecting the battery
cable before doing any further work. The SRS system
is designed to retain enough voltage to deploy the air
bag even after the battery has been disconnected. Serious
injury may result from unintended air bag deployment
if work is done on the SRS system immediately after
the battery cable is disconnected.

wrench from the back side.
(2) When disconnecting the connector of the clock spring
from the air bag module, press the air bag's lock toward
the outer side to spread it open. Use a screwdriver, as
shown in the figure at the left, to pry so as to remove
the connector gently.
Caution

spring connector, take care not to apply excessive
force to it.
2. The removed air bag module should be stored
in a clean, dry place with the pad cover face up.
