SUPPLEMENTAL INFLATABLE RESTRAINTS (SIR) 8B – 57
DAEWOO V–121 BL4
DTC 52
Driver Side Airbag Deployment Loop Resistance Is High
CAUTION : The sensing and diagnostic module(SDM)
can maintain sufficient voltage to deploy the irabags
and pretensioners for 1 minute after the ignition is
OFF and the fuse has been removed. If the airbags
and pretensioners are not disconnected, do not be-
gin service until one minute has passed after discon-
necting power to SDM. Otherwise, injury could result.
CAUTION : During service procedure, be very careful
when handling the SDM. Never strike or jar the SDM.Never power the supplemental inflatable re-
straints(SIR) when the SDM is not rigidly attached to
the vehicle. All SDM mounting bolts must be carefully
tightened , and the arrow on the SDM must be point
toward the front of the vehicle to ensure proper op-
eration of the SIR. The SDM could be activated if it is
powered when it is not rigidly attached to the vehicle,
resulting in unexpected deployment and possible in-
jury.
