DIAGNOSTIC TROUBLE CODE (DTC) 32
AIRBAG INFLATION RECORD BY FRONTAL COLLISION
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.
In case of airbag inflation by a vehicle collision, the SDMmaintains warning lamp ”ON” and then all the airbag sys-
tem including SDM, Airbag Module and wiring should be
replaced.
DTC 32 Will Set When
S The history of airbag inflation or belt pretensioner
explosion is in the SDM.
DTC 32 Airbag Inflation Record By Frontal Collision
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 carefulwhen 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.
