DTC 56 Passenger Side Airbag Deployment Loop Resistance Is
High
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.

11. Visually check any damage for the passenger
side airbag wiring and connector. Is the airbag
wiring damaged or the connector discon-
nected?–Go to Step 2Go tostep 3
2Repair the wiring damage or connect the connector.
Check the system again.–––
31. Confirm the ignition switch ”OFF”.
2. Disconnect the connector of passenger side
airbag module.
3. Remove the connector of SDM.
4. Check the resistance between the terminal 1,2
of passenger side airbag module and the termi-
nal 16,17 of SDM. Is the resistance 10KΩ? 10K ΩGo to Step 4Replace 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.–––

DIAGNOSTIC TROUBLE CODE (DTC) 57
PASSENGER SIDE AIRBAG DEPLOYENT LOOP
RESISTANCE IS LOW
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
side airbag module by letting the infinitesimal current flow
through the internal circuit and verify the resistance.
DTC 57 Will Set When
S The resistance of driver side airbag deployment
loop is lower than 1.4 ohms.
S The shorting bar is damaged and then the SDM
must be replaced .
