DIAGNOSTIC TROUBLE CODE (DTC) 8
PASSENGER AIRBAG DEPLOYMENT LOOP IS SHORTED
TO POWER
Circuit Description
When the ignition switch is turned to ON, the sensing and
diagnostic module(SDM) will perform turn–on test to diag-
nose critical malfunctions within SDM itself.
Upon passing these test ignition and deployment loop volt-
ages are measured to ensure that they are within their nor-
mal voltage ranges. The SDM monitors the voltages at the
driver low and the passenger low to detect shorts to
ground or voltage in the deploy loops.The SDM checks the wiring connection to the passenger
airbag module by letting the infinitesimal current flow
through the internal circuit and verify the resistance. If the
resistance is in the 2 kilo ohms between 10 kilo ohms, the
defect may occur depending upon SDM. The normal re-
sistance is over 10 kilo ohms.
DTC 8 Will Set When
S The airbag wiring of passenger’s high is shorted to
battery wiring.
S The airbag wiring of passenger’s low is shorted to
battery wiring.

Passenger Airbag Deployment Loop Is Shorted To Power
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
