TROUBLE CODE DIAGNOSIS - GASOLINE VEHICLE
TCM DIAGNOSTIC SYSTEM
OVERVIEW
Notice: To prevent Transmission Control Module (TCM)
damage. The ignition key must be OFF when
disconnection or reconnection the power to the TCM
(for example bttery cable, TCM pigtail connector, TCM
fuse, jumper cables, etc.).
When the TCM detects a system fault, a Diagnostic
Trouble Code (DTC) is set in the TCM. This code is
present while the fault conditions are met and is stored
as a ‘History DTC’ until cleared. Condition for setting
and clearing each TCM DTC are provided in the relevant
sections.
In the case where the vehicle type is certified for Eure
On-Board Diagnostic (EOBD) compliance, the Engine
Control Module (ECM) provides the communication linkto the EOBD scan tool to pass on any EOBD relevant
codes from the TCM. The table below contains a list of
all supported DTCs and the classification of each for
EOBD purposes. Where a type B DTC has been set in
an EOBD vehicle, the response to the fault may include
action by the ECM, including the illumination of the
Malfunction lndicator Lamp (MIL). Refer to Section 1F,
Engine Control, for details on EOBD system function,
checks and fault clearing.
CLEARING TROUBLE CODES
TCM DTCs should be cleared after repairs have been
completed. Some diagnostic tables will tell you to clear
the codes before using the chart, which will help to
find the cause of the problem more quickly. Always
note the DTCs present before clearing - this information
may be helpful in the diagnostic process.”

5A-62 AUTOMATIC TRANSMISSION
SSANGYONG MY2002
Circuit Description
The Transmission Fluid Temperature (TFT) sensor is a
thermistor located in the solenoid wiring loom within
the valve body of the transmission. This sensor is a
typical Negative Temperature Coefficient (NTC) resistor
with low temperatures producing a high resistance and
high temperatures producing a low resistance.
If the transmission fluid temperature exceeds 135 °C
(275 °F), the TCM will impose converter lock-up at lower
vehicle speeds. Favour a lower gear to increase engine
speed, and in some vehicles flashes the mode indicator
lamp. This results in maximum oil flow through the exter-
nal oil cooler and eliminates slippage in the torque
converter. Both these actions combine to reduce the
oil temperature in the transmission.
The DTC P0710 sets when the TFT sensor signal is not
feasible.
Conditions for Setting the DTC
Transmission fluid temperature sensor signal is
greater than 4.88 volts (immediate detection).
Transmission fluid temperature sensor signal is less
than 0.21 volts (immediate detection).
Transmission temperature has not changed by 2 °C
in 15 minutes since ignition on and temperature is
less than 20 °C or greater than 125 °C.
Action Taken When the DTC Sets
Transmission fluid temperature is assumed to be
120 °C (248 °F).
All shifts will be firm until the transmission has
warmed up because a high transmission fluid
temperature is assumed.
DIAGNOSTIC TROUBLE CODE (DTC) P0710
TRANSMISSION FLUID TEMPERATURE SENSOR CIRCUIT
MALFUNCTION
Conditions for Clearing the DTC
The DTC will clear when the malfunction has not oc
curred for 3 seconds.
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
The voltage measured by the TCM across the trans-
mission fluid temperature input terminals has been
outside acceptable levels.
If the DTC sets when an accessory is operated,
check for a poor connection or excessive current
draw.
Inspect the wiring for poor electrical connections
at the TCM and at the 10-way transmission
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 wires inside the insulation.
In searching for a possible intermittent short or open
condition, move or massage the wiring harness
while observing test equipment for a change.
Test Description
The number(s) below refer to the step number(s) on
the Diagnostic Table.
5. This step simulates a DTC P0710 condition. If the
scan tool displays the specified value, the TFT
sensor signal circuit and the TCM are OK.

SSANGYONG MY2002
Circuit Description
The solenoid 1 is used to control fluid flow acting on
the 1 - 2 shift valve. The solenoid 1 is a normally open
ON/ OFF type solenoid that is used in conjunction with
the solenoid 2 to allow four different shifting
combinations. Refer to Solenoid Logic for Static Gear
States. 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 P1733 sets when the Solenoid 1 (S1) circuit
is open or the switched leg of the solenoid 1 is shorted
to battery positive.
Conditions for Setting the DTC
DTCs P1717 and P1718 are not set.
S1 is OFF.
S2 is OFF.
The solenoid 1’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 1 is always OFF.
TCM adopts a Limp Home Mode (LHM) operation.

SOLENOID 1 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 1 is turned OFF/
ON by a very small (4 millisecond) pulse. 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 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.
