DTC 14
Passenger Belt Pretensioner Deployment Loop
Resistance Is Low
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
1Visually inspect the connector and the wiring of pas-
senger belt pretensioner. Is the connector discon-
nected?–Connect the
connector.Go to Step 2
21. Confirm the ignition switch ”OFF”.
2. Disconnect the connector of the passenger belt
pretensioner.
3. Disconnect the connector of SDM wiring.
4. Check the resistance between the terminal 1
and 2 of passenger belt pretensioner. Is the
resistance ?Go to Step 3Replace the
airbag wiring.
31. Replace the SDM.
2. Confirm the ignition switch ”ON”.
3. Erase the DTC using scan tool.
4. Perform the SIR Diagnostic System Check.
Does the DTC still exist?–Go to Sep 4System is OK.
4Replace the passenger belt pretensioner.–––

DIAGNOSTIC TROUBLE CODE (DTC) 15
PASSENGER BELT PRETENSIONER DEPLOYMENT
LOOP IS SHORTED TO GROUND
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.
DTC 15 Will Set When
S The belt pretensioner wiring of passenger’s high is
shorted to ground.
S The belt pretensioner wiring of passenger’s low is
shorted to ground.
