SsangYong Korando II (1996-2006 year). Manual - part 402

SSANGYONG MY2002

8B-22 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),
p a s s e n g e r l o w ( t e r m i n a l 1 1 ) , d r i v e r s e a t b e l t
pretensioner low (terminal 7) and passenger seat belt
pretensioner low (terminal 4) to detect short to voltage
in the deployment loops.

DTC 03 Will Set When

DTC 03 will set when the driver seat belt pretensioner
low is above 5 volts for 250 milliseconds while the other

DIAGNOSTIC TROUBLE CODE (DTC) 03

DRIVER SEAT BELT PRETENSIONER SHORTED TO VOLTAGE

deployment loop low 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
4) and set DTC 03. The SDM will shutdown the driver
seat belt pretensioner deployment loop.

DTC 03 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 03 - Driver Seat Belt Pretensioner 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
s e r v i c e u n t i l o n e m i n u t e h a s p a s s e d a f t e r
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.

1. Disable the Supplemental Restraint System (SRS).

Refer to “Disabling the Supplemental Restraint
System (SRS)” in this section.

2. Virtually inspect the driver seat belt pretensioner

circuit and connectors, especially at the SDM.

Is there any evidence of rubbing, damage or chafing?
1. Repair the damaged wires or connectors.
2. Connect all the SRS components.
Is the repair complete?
1. Disconnect the SDM connector.
2. Disconnect driver airbag.
3. Turn the ignition ON.
4. Measure the voltage between terminal 1 (or 2) of

the driver seat belt pretensioner connector and
ground.

Is the voltage within the specified value?
1. Repair short to voltage in driver seat belt

pretensioner deployment loop.

2. Connect all SRS components.
Is the repair complete?
1. Connect dummy resistance (2.15 ± 0.35

Ω

) to

driver seat belt pretensioner connector instead of
driver seat belt pretensioner.

2. Enable the SRS.
3. Connect the scan tool to the data link connector

(DLC).

4. Clear DTC and request DTC.
Is the DTC 03 still present?
Replace driver seat belt pretensioner.
Is the repair complete?

1. Replace SDM.
2. Connect all SRS components.
