SSANGYONG MY2002
Output circuits which control external devices such
as the Variable Pressure Solenoid (VPS) driver, On/
Off solenoid drivers, a diagnostics output and the
driving mode indicator light.
Processing Logic
Shift schedule and calibration information is stored in
an Erasable Programmable Read Only Memory (EPROM).
Throttle input calibration constants and the diagnostics
information are stored in Electrically Erasable Program-
mable Read Only Memory (EEPROM) that retains the
memory even when power to the TCM is disconnected.
TCM continuously monitors the input values and uses
these, via the shift schedule, to determine the required
gear state. At the same time it monitors, via the solenoid
outputs, the current gear state, whenever the input
conditions change such that the required gear state is
different to the current gear state, the TCM initiates a
gear shift to bring the two states back into line.
Once the TCM has determined the type of gearshift
required the TCM accesses the shift logic, estimates
the engine torque output, adjusts the variable pressure
solenoid ramp pressure then executes the shift.The TCM continuously monitors every input and output
circuit for short or open circuits and operating range.
When a failure or abnormal operation is detected the
TCM records the condition code in the diagnostics
memory and implements a Limp Home Mode (LHM).
The actual limp home mode used depends upon the
failure detected with the object to maintain maximum
drive-ability without damaging the transmission. In
general input failures are handled by providing a default
value. Output failures, which are capable of damaging
the transmission, result in full limp mode giving only
third or fourth gear and reverse. For further details of
limp modes and memory retention refer to the
Diagnostic Trouble Code Diagnosis Section.
The TCM is designed to operate at ambient
temperatures between - 40 and 85 °C (- 40 and 185 °F).
It is also protected against electrical noise and voltage
spikes, however all the usual precautions should be
observed, for example when arc welding or jump
starting.
TCM Inputs
To function correctly, the TCM requires engine speed,
vehicle speed, transmission fluid temperature, throttle
position, gear position and Kickdown Switch inputs to
determine the variable pressure solenoid current ramp
and on/off solenoid states.

This ensures the correct gear selection and shift feel
for all driving conditions.
The inputs required by the TCM are as follows;

DIAGNOSTIC TROUBLE CODES (Cont'd)
DTC Types
Each DTC is directly related to a diagnostic test. The
Diagnostic management system sets DTCs based on
the failure of the tests during a driving cycle or cycles.
The following are the two types of DTCs and the charac-
teristics of those codes;
Type B
Emissions related.
EOBD system “Armed” after one driving cycle with
a fail.
EOBD system “Disarmed” after one driving cycle
with a pass.
Illuminates the MIL on the second con-secutive
driving cycle with a fail.
TCM stores a history DTC on the first driving cycle
with a fail.
EOBD system stores a history DTC on the second
consecutive driving cycle with a fail, (the DTC will
be armed after the first fail).
EOBD system stores a freeze frame on the second
consecutive driving cycle with a fail, (if empty).
Type D
Non-Emissions related.
Does not request illumination of any lamp.
Stores a history DTC on the first driving cycle with
a fail.
EOBD system does not store a freeze frame. DTC

5A-54 AUTOMATIC TRANSMISSION
SSANGYONG MY2002
Circuit Description
The Transmission Range (TR) sensor is incorporated
in the inhibitor switch mounted on the side of the
transmission case. The TR sensor Indicates to the TCM
which gear position has been selected by way of a
varying resistance.
The TR sensor signal has discrete values indicating
the positions selected by the gear shift control lever
(PRND321). The Transmission Control Module (TCM)
receives that signal with a voltage varying from 0 V to
5 V. DTC P0706 sets when the TR sensor signal is not
feasi ble.
Conditions for Setting the DTC
•The engine temperature is greater than 60 °C (140 °F).
The engine speed is greater than 2000 RPM and
less than 4000 RPM.
Engine load is greater than 60 %.
DTCs P0707, P0708, P1703 and P1719 are not set.
Transmission temperature is greater than 0 °C (32 °F)
or if P0710 is present the engine coolant
temperature is greater than 60 °C (140 °F).
The TR sensor indicates that the transmission is in
a neutral state, however the engine output torque
indicates that a drive gear load is present. This
condition must be continuously present for 5
seconds.
DIAGNOSTIC TROUBLE CODE (DTC) P0706
TRANSMISSION RANGE SENSOR CIRCUIT RANGE/PERFORMANCE
Action Taken When the DTC Sets
The Malfunction Indicator Lamp (MIL) will illuminate
on the second consecutive driving cycle with the
DTC present.
The EOBD system will record operating conditions
at the time the diagnostic fails. This information will
be stored in the Failure Records buffer.
TR signal is assumed to be in the Drive position.
The transmission is limited to 2nd and R gears only.
Namely 1st, 3rd and 4th gears are inhibited.
Torque Converter Clutch (TCC) is disabled.
Conditions for Clearing the DTC
The DTC will clear when the malfunction has not oc-
curred for 30 seconds and TR is in P, R, N or D.
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 at the TR sensor connector. Look
for possible bent, backed out, deformed or damaged
ter-minals. 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 in-sulation.

5A-56 AUTOMATIC TRANSMISSION
SSANGYONG MY2002
Circuit Description
The Transmission Range (TR) sensor is incorporated
in the inhibitor switch mounted on the side of the
transmis sion case. The TR sensor Indicates to the
TCM which gear position has been selected by way of
a varying resistance.
The TR sensor signal has discrete values indicating
the positions selected by the gear shift control lever
(PRND321). The Transmission Control Module (TCM)
receives that signal with a voltage varying from 0 V to
5 V. DTC P0707 sets when the TR sensor signal is
faulty, causing the gear lever position signal to be less
than 0.87 V.
Conditions for Setting the DTC
TR sensor signal is less than 0.87 V.
The above condition must be continuously present
for 100 milliseconds.
Action Taken When the DTC Sets
The Malfunction Indicator Lamp (MIL) will illuminate
on the second consecutive driving cycle with the
DTC present.
The EOBD system will record operating conditions
at the time the diagnostic fails. This information will
be stored in the Failure Records buffer.
Transmission range is assumed to be in the Drive
position.
The transmission is limited to 2nd and R gears only.
Namely 1st, 3rd and 4th gears are inhibited.
Torque Converter Clutch (TCC) is disabled.
DIAGNOSTIC TROUBLE CODE (DTC) P0707
TRANSMISSION RANGE SENSOR CIRCUIT LOW INPUT
Conditions for Clearing the DTC
The DTC will clear when the malfunction has not
occurred 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 TR
sensor input terminals has been below on
acceptable level for a significant length of time.
This would typically be caused by a short to ground
in the wiring to, or within, the inhibitor switch which
has caused the signal at the TCM to read about 0
V.
Inspect the wiring for poor electrical connections
at the TCM and at the TR sensor connector. Look
for possible bent, deformed or damaged terminals.
Also, check for chafed wires that could short to bare
metal or other wiring.
In searching for a possible intermittent short or open
condition, move or massage the wiring harness
while observing the test equipment for a change.
Test Description
The number(s) below refer to the step number(s) on
the Diagnostic Table.
3. This step simulates a DTC P0708 condition. If the
scan tool displays the specified value, the TR
sensor signal circuit and the TCM are OK.

Circuit Description
The Transmission Range (TR) sensor is incorporated
in the inhibitor switch mounted on the side of the
transmission case. The TR sensor Indicates to the
TCM which gear position has been selected by way of
a varying resistance.
The TR sensor signal has discrete values indicating
the positions selected by the gear shift control lever

The transmission range sensor is faulty, causing the
gear lever position signal to be greater than 4.12 V.
Conditions for Setting the DTC
TR sensor signal is greater than 4.12 V.
The above condition must be continuously present
for 100 milliseconds.
Action Taken When the DTC Sets
The Malfunction Indicator Lamp (MIL) will illuminate
on the second consecutive driving cycle with the

The EOBD system will record operating conditions
at the time the diagnostic fails. This information
will be stored in the Failure Records buffer.
Transmission range (gear lever) is assumed to be
in the Drive position.
 The transmission is limited to 2nd and R gears only.
Namely 1st, 3rd and 4th gears are inhibited.
Torque Converter Clutch (TCC) is disabled.
Manually initiated downshifts will not be available.
DIAGNOSTIC TROUBLE CODE (DTC) P0708
TRANSMISSION RANGE SENSOR CIRCUIT HIGH INPUT
Conditions for Clearing the DTC
The DTC will clear when the malfunction has not
occurred 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 shift
lever input terminals has been above an acceptable
level for a significant length of time.
This would typically be caused by a loose
connection or an open or short to B+ in the wiring
to, or within, the inhibitor switch which has caused
the signal at the TCM to read 5 V.
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 TR sensor 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
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.
