Ml3lDBG20. REMOVAL OF AIR BAG MODULE
(1) Remove the negative terminal of the battery and wait
for more than 30 seconds.
CautionThe capacitor in the SRS diagnosis unit retains
enough voltage to deploy the air bag for a given
period even after disconnection of the battery. If anoperation is performed during that given period,
unintended deployment of the air bag could result
and cause serious injury.(2) Remove the air bag module. To remove the clock spring
connector (squib connector) from the air bag module,
force the lock outward and pry it with a plain screwdriv-
er as shown at left so that no undue force will be
exerted on the connector when it is removed.
(3) The removed air bag module should be stored in a
clean, dry, flat place with the pad side up.
