Circuit Description
When the ignition switch is turned to ON, the sensing
and diagnostic module (SDM) will perform tests to
diagnose critical malfunctions within SDM itself. Internal
fault DTC will set when any of the malfunctions detected
by SDM itself. Refer to “Diagnostic Trouble Code
Table” in this section.
DIAGNOSTIC TROUBLE CODES (DTCS) - INTERNAL FAULT
Action Taken
The SDM will turn on the airbag indicator and set
diagnostic trouble code.
The SDM will shutdown its function partially or totally.
Diagnostic Trouble Code (DTC) - Internal Fault
Caution: The sensing and diagnosis module (SDM)
can maintain sufficient voltage to deploy the airbags
and pretensioners for 0.15 seconds after the ignition
is OFF and the fuse has been removed. If the airbags
or pretensioners are not disconnected, do not begin
service until one minute has passed after
disconnecting power to the 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 restraints
system (SRS) when the SDM is not rigidly attached
to the vehicle. Also SDM mounting nuts must be
carefully tightened to ensure proper operation of
the SRS. The SDM could be activated if it is powered
when it is not rigidly attached to the vehicle,
resulting in unexpected deployment and possible
injury.

8B-18 SUPPLEMENTAL RESTRAINTS SYSTEM
Circuit Description
When the ignition switch is turned to ON, the sensing
and diagnostic module (SDM) will perform tests to diag-
nose critical malfunctions within SDM itself. Upon pass-
ing these tests ignition and deployment loop voltages
are measured to ensure that they are within their re-
spective normal voltage ranges. The SDM monitors the
voltages at the driver low (terminal 14), passenger low
(terminal 11), driver seat belt pretensioner low (terminal
7) and passenger seat belt pretensioner low (terminal
4) to detect short to voltage in the deployment loops.
DTC 01 Will Set When
DTC 01 will set when the driver low is above 5 volts for
250 milliseconds while the other deployment loop low
is below 5 volts and ignition voltage is within the normal
operating voltage range.
DIAGNOSTIC TROUBLE CODE (DTC) 01
DRIVER DEPLOYMENT LOOP SHORTED TO VOLTAGE
This test is run during start-up test and every 250
milliseconds during continuous monitoring.
Action Taken
The SDM will turn on the airbag indicator (blink mode
3) and set DTC 01. The SDM will shutdown deployment
loop of driver airbag module.
DTC 01 Will Clear When
The scan tool CLEAR CODES command is received.
Diagnostic Aids
Carefully inspect the wires in driver airbag deployment
loop for cutting or chafing.

DTC 01 - Driver Deployment Loop Shorted to Voltage
Caution: The sensing and diagnosis module (SDM)
can maintain sufficient voltage to deploy the air-
bags and pretensioners for 0.15 seconds after the
ignition is OFF and the fuse has been removed. If
the airbags or pretensioners are not disconnected,
do not begin service until one minute has passed
after disconnecting power to the SDM. Otherwise,
injury could result.Caution: During service procedure, be very careful
when handling the SDM. Never strike or jar the SDM.
