SUPPLEMENTAL INFLATABLE RESTRAINTS (SIR)
DAEWOO V–121 BL4
Sensing and Diagnostic Module (SDM) Integrity Check
CAUTION : The SDM can maintain sufficient voltage
to deploy the airbags for 10 minutes after the ignition
is OFF and the fuse has been removed. If the airbags
are not disconnected, service cannot begin until 10
minutes have passed after disconnecting power to
the SDM.
CAUTION : During service procedures, be very care-
ful when handling the SDM. Never strike or jar the
SDM. Never power the SIR system when the SDM is
not rigidly attached to the vehicle. All SDM mounting
bolts must be carefully tightened, and the SDM arrow
must be pointing toward the front of the vehicle to en-
sure proper operation of the SIR system. The SDM
could be activated if it is powered when it is not rigidly
attached to the vehicle, resulting in unexpected de-
ployment and possible injury.
