8B-20 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 voltage
in the deployment loops.
DTC 02 Will Set When
DTC 02 will set when the driver low is above 5 volts for
250 milliseconds while the other deployment loop low
DIAGNOSTIC TROUBLE CODE (DTC) 02
PASSENGER DEPLOYMENT LOOP SHORTED TO VOLTAGE
is below 5 volts and ignition voltage is within the normal
operating voltage range. 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 02. The SDM will shutdown the
passenger airbag deployment loop.
DTC 02 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.
KAA8B100
DTC 02 - Passenger Deployment Loop Shorted to Voltage
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.
