5A-78 AUTOMATIC TRANSMISSION
SSANGYONG MY2002
Circuit Description
The Air Conditioning Switch circuit indicates the state
of the air conditioning compressor clutch (on or off).
This signal is available to the TCM only on vehicles
fitted with air conditioning.
The DTC 1710 sets when an intermittent connection in
the air conditioning switch circuit has been detected.
The switch input is rapidly changing states and the
switching frequency is greater than 8.3 Hz.
Conditions for Setting the DTC
The mode switching frequency is greater than 8.3
Hz.
The above condition must be continuously present
for 4 state changes.
Action Taken When the DTC Sets
The TCM does not compensate for torque variation
due to air conditioning compressor clutch activation.
DIAGNOSTIC TROUBLE CODE (DTC) P1710
AIR CONDITIONING SWITCH CIRCUIT MALFUNCTION
Conditions for Clearing the DTC
The DTC will clear after 3 seconds without the fault.
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
This fault is caused by too many changes in the
mode input signal over a period of time.
Typical causes would be an intermittent connection
in the switch or wiring or an intermittent short to
ground in the wiring.

Circuit Description
The Controller Area Network (CAN) connects various
control modules by using a twisted pair of wires, to
share common information. This results in a reduction
of sensors and wiring. TCM obtains the actual engine
speed and throttle position, vehicle speed and
accelerator pedal position etc. from ECM via CAN
without any additional sensors.
The DTC P1713 sets when the accelerator pedal signal
via CAN is out of range. The accelerator pedal signal
is greater than 254 steps.
Conditions for Setting the DTC
DTCs P1719 is not set.
The accelerator pedal signal is greater than 254
steps. The malfunction is triggered immediately
after this condition exists.
Action Taken When the DTC Sets
4th gear is inhibited.
Torque Converter Clutch (TCC) is inhibited.
Default value is adopted for shift point decisions.
Accelerator pedal is not used for P, R, or N B2
activation decisions.
Conditions for Clearing the DTC
The DTC will clear when the malfunction has not
occurred for 30 seconds.
DIAGNOSTIC TROUBLE CODE (DTC) P1713
PEDAL SIGNAL ERROR
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
Inspect the wiring for poor electrical connections
at the TCM and ECM connectors. 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.
If diagnosing for a possible intermittent short or
open condition, move or massage the wiring harness
while observing test equipment for a change.
When ECM finds a fault on the accelerator pedal
signals, ECM will adopt a default mode and send
the default value and trouble message to TCM via
CAN.
Test Description
The number(s) below refer to the step number(s) on
the Diagnostic Table.
3. Check if there are any DTCs related to the accelera-
tor pedal sensor on the ECM side.
4. Check for a poor connection at the ECM and TCM
connectors.

Circuit Description
The Controller Area Network (CAN) connects various
control modules by using a twisted pair of wires, to
share common information. This results in a reduction
of sensors and wiring. TCM obtains the actual engine
speed and throttle position, vehicle speed and
accelerator etc. from ECM via CAN without any
additional sensors.
The DTC P1721 sets when the throttle signal via CAN
is out of range. The throttle is greater than 254 steps.
Conditions for Setting the DTC
DTC P1719 is not set.
The throttle is greater than 254 steps. The malfunc-
tion triggers immediately after the above condition
occurs.
Action Taken When the DTC Sets
The throttle signal is defaulted to 100 %.
Shift quality is degraded.
All shifts will be firm as full throttle and hence high
engine torque is assumed.
Line pressure will always stay high (S6 OFF) to cope
with the assumed high throttle/ torque.
Manual 1 gear selection is inhibited.
Conditions for Clearing the DTC
The DTC will clear if the malfunction is not present
for 30 seconds.

5A-126 AUTOMATIC TRANSMISSION
SSANGYONG MY2002
Circuit Description
The solenoid 7 is a normally open ON/OFF type sole-
noid that is used to control the application of the
Torque Converter Clutch (TCC).
The Solenoid 7 (S7) ON activates the TCC and the S7
is attached to the pump body within the transmission.
Voltage is supplied directly to the solenoid through
the Transmission Control Module (TCM).
The DTC P1739 sets when the solenoid 7, Torque Con-
verter Clutch Solenoid, circuit is open or the switched
leg of the solenoid 7 is shorted to battery positive.
The solenoid 7's driver Integrated Chip (IC) status
indicates a faulty circuit.
Conditions for Setting the DTC
DTCs P1717 and P1718 are not set.
S7 is OFF.
S3 is OFF.
The solenoid 7'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 7 is always disabled (OFF) resulting
in the TCC being unlocked always.
DIAGNOSTIC TROUBLE CODE (DTC) P1739
SOLENOID 7 CIRCUIT OPEN
Conditions for Clearing the DTC
The DTC will clear when the malfunction has not
occurred after ignition cycle.
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 7 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 recorede.
Typical causes would be an open circuit in the wiring
to or within the solenoid, or a short circuit to power
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 10-way transmission
connector.
