Circuit Description
The solenoid 2 is used to control fluid flow acting on
the 2 - 3 shift valve. The solenoid 2 is a normally open
ON/OFF type solenoid that is used in conjunction with
the solenoid 1 to allow four different shifting
combinations. Refer to Static Gear Status.
The solenoid is attached to the valve body within the
transmission. Voltage is supplied directly to the
solenoid through the Transmission Control Module
(TCM).
The DTC P1742 sets when the Solenoid 2 (S2) circuit
is shorted to ground. The solenoid 2’s driver
Integrated Chip (IC) status indicates a faulty circuit.
Conditions for Setting the DTC
DTCs P1717 and P1718 are not set.
S2 is ON.
The solenoid 2’s driver Integrated Chip (IC) status
indicates a faulty circuit. This condition must be
continuously present for 60 milliseconds.
Action Taken When the DTC Sets
The solenoid 2 is always OFF.
TCM adopts a Limp Home Mode (LHM) operation.
Conditions for Clearing the DTC
The DTC will clear when the malfunction has not
occurred after ignition cycle.
DIAGNOSTIC TROUBLE CODE (DTC) P1742
SOLENOID 2 CIRCUIT SHORT
A history DTC will clear after 40 TCM power-up
cycles with a warm transmission (>50 °C) and
without a fault.
History DTCs can be cleared by using a scan tool.
Diagnostic Aids
During the TCM’s testing, solenoid 2 is turned OFF/
ON by a very small (4 millisecond) pulses. This
pulse is too short for the solenoid to react so the
transmission operation is not affected.
The solenoid feedback voltage is measured before
the (4 millisecond) pulse and again during the pulse.
If the difference is outside the acceptable limits
the relevant fault is recorded.
Typical causes would be a short circuit to ground
in the wiring to or within the solenoid.
If several faults of solenoids are present, check the
wiring or connectors that are common to the selected
solenoids, especially the earth connections.
Inspect the wiring for poor electrical connections
at the TCM and at the transmission 10-way
connector. Look for possible bent, backed out,
deformed or damaged terminals. Check for weak
terminal tension as well. Also check for chafed wires
that could short to bare metal or other wiring.
Inspect for broken wire inside the insulation.

Both Speed Sensor Faulty
If both the front and rear speed sensors are faulty con
tinuously for 0.5 seconds the 4WD CHECK lamp is
illuminated. The TCCU then responds as follows:
1. If the system is in high range the TCCU sets the
EMC touch off level based on a vehicle speed of
0 and wheel slip control is suspended.
2. If the system is in low range, the EMC duty cycle
is set to maximum until the system is shifted out
of low range.
3. All electric shift activity is halted until the Ignition
is cycled. If a shift is in progress it will be
completed.
If both speed sensors recover continuously for 0.5 sec-
ond the TCCU will function normally. The 4WD CHECK
lamp is turned off but the fault code will remain in
memory.
Electro-Magnetic Clutch Test
The electromagnetic clutch (EMC) is tested for open
circuit or short circuit to ground. If a fault is detected
continuously for 0.8 second the 4WD CHECK lamp is
turned on and all TODTM activity is halted.
If the EMC recovers continuously for 0.8 second the
TCCU will function normally. The 4WD CHECK lamp is
turned off but the fault code will remain in memory.
DIAGNOSTIC TROUBLE CODES
(DTCS)
When a fault is detected a diagnostic trouble code
(DTC) is stored in the TCCU and illuminates the 4WD
CHECK indicator. This DTC will remain in memory until
the TCCU is instructed to erase DTCs by scan tool.
Notice: DTCs can not be erased by disconnecting of
power supply to the TCCU.

SUPPLEMENTAL RESTRAINTS SYSTEM 8B-3
SSANGYONG MY2002
SUPPLEMENTAL RESTRAINT
SYSTEM (SRS)
The supplemental restraint system (SRS) is safety de-
vice used in conjunction with the seat belts.
The air bag does not replace the function of the
seatbelt. The driver and the passengers must always
fasten their seat belts adjust them for a proper fit.
The SRS is designed to protect the driver and the front
seat passenger in the event of a significant frontal im-
pact to the vehicle. The airbags deploy if the force is
applied from a direction within about 30 degrees of
the vehicle’s centerline.
The SRS system consists of the following components:
Driver side airbag module.
Passenger airbag module.
Driver’s and passengers front seat belt pretension-
ers.
Sensing and diagnostic module (SDM).
Clock spring.
Wire harness and connectors.
Airbag warning lamp on the instrument cluster.
There are there are for separate four separate deploy-
ment loops in the SRS system. The term “loop” is
used because current leaves the SDM and returns to
the SDM during deployment or testing. First loop is
the circuit from SDM to the driver airbag and back to
the SDM. Second loop is the circuit from the SDM to
the passenger airbag and back to the SDM. The third
and forth loops are for right and left pretensioners.
DESCRIPTION AND OPERATION
KAA8B010
deployment, the system will enter overall or partial
shutdown status and the airbag will not inflate. The
Diagnostic System Check reveals diagnostic trouble
codes (DTCs) through the use of scan tool. It also
checks for proper airbag warning lamp operation.
Battery Voltage Check
The SDM checks the battery voltage continuously and
if the voltage is out of normal operating range (9-16
volts), all system diagnosis stops and turns on the
warning warning lamp.
Deployment Line Check
The SDM checks not only low or high resistance in the
deployment loop but also short to battery or ground
condition to indicates defects in deployment loop. It
indicates the defects by blinking the airbag warning
warning lamp.
Safety Function Check
The SDM checks the operation of arming sensor. If
the arming sensor is shorted more than 2 seconds,
the SDM will enter overall shutdown mode.
AIRBAG MODULES
Driver Airbag Module
Caution: Tampering with driver side airbag module
creates the risk of an injury from unexpected de-
ployment. Therefore, the passenger airbag module
should never be disassembled.
The passenger airbag module is under the center pad
of the steering wheel. The driver airbag module contains
an igniter charge and a gas generator to inflate the
folded airbag.
The airbag contains a shorting bar, which short-circuit
the driver high circuit to driver low circuit when the
connector is disconnected. The shorting bar prevents
current from traveling through the driver airbag module
during servicing. The shorting bar is disengaged when
the connector is connected.
System Control
The sensing and diagnostic module (SDM) continuously
monitors and controls the supplemental restraint
system (SRS) function during ignition ON or driving.
When SDM detects any problem it turns on or blink
the airbag warning lamp and keeps the diagnostic
trouble codes (DTCs). If there is a danger of improper
