SSANGYONG MY2002
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.
KAA8B100
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.
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.
Perform the SRS Diagnostic System Check.
