SUPPLEMENTAL INFLATABLE RESTRAINTS (SIR) 8B – 69
DAEWOO V–121 BL4
DTC 58
Passenger Side Airbag Deployment Loop Is Shorted To
Ground
CAUTION : The sensing and diagnostic module(SDM)
can maintain sufficient voltage to deploy the airbags
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.
Step
ActionValue(s)YesNo
11. Confirm the ignition switch ”OFF”.
2. Wait for a minute the SDM charger to be dis-
charged.
3. Visually check any damage for the airbag wir-
ing. Is the airbag wiring damaged?–Go to Step 3Go to Step 2
21. Check the resistance between the SDM and
the high, low terminal of passenger side airbag
module and the ground. Is the resistance
10KΩ?
10K ΩGo to Step 4Go to Step 3
3Replace the airbag wiring.–––
41. Replace the SDM.
2. Confirm the ignition switch ”ON”.
3. Remove the DTC with scan tool.
4. Check the circuit. Does the DTC still exist?–Go to Step 5The System is
OK.
5Replace the passenger side airbag module.–––
