8B-28 SUPPLEMENTAL RESTRAINTS SYSTEM
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. Upon
passing these tests ignition and deployment loop
voltages are measured to ensure that they are within
their respective 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 ground
in the deployment loops.
DTC 06 Will Set When
DTC 06 will set when the voltage at passenger airbag
low falls below a specified value, and ignition voltage
is within the normal operating voltage range.
DIAGNOSTIC TROUBLE CODE (DTC) 06
PASSENGER DEPLOYMENT LOOP SHORTED TO GROUND
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 06. The SDM will shutdown the
passenger airbag deployment loop.
DTC 06 Will Clear When
The scan tool CLEAR CODES command is received.
Diagnostic Aids
Carefully inspect the wires in passenger airbag
deployment loop for cutting or chafing.

DTC 06 - Passenger Deployment Loop Shorted to Ground
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-34 SUPPLEMENTAL RESTRAINTS SYSTEM
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. Upon
passing these tests ignition and deployment loop
voltages are measured to ensure that they are within
their respective normal voltage ranges. The SDM then
proceeds with resistance measurement test. Driver low
terminal 14 is grounded through a current sink. The
current source is connected to driver high terminal 13
to allow a known amount of the current flow. By
monitoring the voltage difference between drive high
and driver low, the SDM calculates the combined
resistance of the driver inflator module, the clock
spring, the harness wiring, and connector terminal
contacts.
DTC 17 Will Set When
DTC 17 will set when the resistance of the driver airbag
deployment loop is above specified value (4.5 ± 0.5 Ω).
DIAGNOSTIC TROUBLE CODE (DTC) 17
DRIVER DEPLOYMENT LOOP RESISTANCE HIGH
The test is run once each ignition cycle during the
resistance measurement test when the ignition voltage
is above a specified value.
Action Taken
The SDM will turn on the airbag indicator (blink mode
1) and set DTC 17. And driver airbag deployment loop
shutdown.
DTC 17 Will Clear When
The ignition switch is turned OFF or the scan tool
CLEAR CODES command is received.
Diagnostic Aids
All intermittent condition is likely to be the caused by
a poor connection from the driver airbag to the clock
spring or SDM terminal 13 or 14. The test for this DTCis
run only while the airbag indicator is performing the
start-up test. When a scan tool CLEAR CODES
command is issued and the malfunction is still present,
the DTC will not reappear until next ignition cycle.
KAA8B100
DTC 17 - Driver Deployment Loop Resistance High
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.
