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.

5A-82 AUTOMATIC TRANSMISSION
SSANGYONG MY2002
Circuit Description
The Kickdown Switch is used to signal the TCM that
the driver requires kickdown indicating the driver
pressed the accelerator to the floor. When this switch
is used in high range non-winter mode driving, the
POWER light comes ON.
The DTC sets when the kickdown switch has an inter-
mittent connection or is stuck ON. Kickdown Switch is
closed when other signals indicate otherwise, i.e. the
accelerator pedal is released and the engine is running.
Or the switch is cycling open/closed more rapidly than
the normal operation allows.
Conditions for Setting the DTC
DTCs P1703, P1713 and P1719 are not set.
Kickdown Switch is closed when other signals indi-
cate otherwise, i.e. the accelerator pedal is released
and the engine is running.
The switch is cycling open/closed more rapidly than
normal operation allows : 10 state changes in less
than 30 milliseconds.
Action Taken When the DTC Sets
Kickdown Switch feature is disabled while the fault
exists.
Conditions for Clearing the DTC
The DTC will clear when the malfunction has not
occurred for 30 seconds.
DIAGNOSTIC TROUBLE CODE (DTC) P1712
KICKDOWN SWITCH CIRCUIT MALFUNCTION
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
Typical causes would be an short circuit within the
switch, or a short circuit to ground in the wiring to
the switch.
Inspect the wiring for poor electrical connections
at the TCM and at the Kickdown Switch connector.
Look for possible bent, backed out, deformed or
damagednterminals. 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.
Test Description
The number(s) below refer to the step number(s) on
the Diagnostic Table.
4. Checks if the kickdown signal circuit is
malfunctioning.
7. Checks if the kickdown ground circuit is
malfunctioning.
8. Check resistance between Kickdown Switch termi-
nal 4 and 2.
12. Check connections of other connectors.

5A-86 AUTOMATIC TRANSMISSION
SSANGYONG MY2002
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.

SSANGYONG MY2002
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 P1716 sets when the throttle signal via CAN
is out of range. The throttle is greater than 254 steps.
Conditions for Setting the DTC
The minimum & maximum throttle positions have
not been learnt by the TCU.
Action Taken When the DTC Sets
The minimum & maximum throttle positions are set
to their factory default values.
Incorrect sensitivity to driver demand.
Incorrect gear shift points.
DIAGNOSTIC TABLE CODE (DTC) 1716
THROTTLE NOT LEARNT ERROR
Conditions for Clearing the DTC
Throttle learns 0 % position. This value must be
greater than 0.2 V.
Diagnostic Aids
This fault indicates that the TCU has not learnt the
throttle position correctly since installation in the
vehicle or that the throttle setting have been cleared
by a diagnostic tool.
Test Description
The number(s) below refer to the step number(s) on
the Diagnostic Table.
4. The “Throttle Position Calibration Procedure” needs
to be carried out. This is given in this section.

The DTC P1719 sets when the information required by
TCM is not available on the CAN. One or more CAN
messages used by the TCM is timed out, i.e. not re-
freshed for 1 second.
Conditions for Setting the DTC
One or more CAN messages used by the TCM are
timed out, i.e. not refreshed for 1 second.
Action Taken When the DTC Sets
TCM uses default values for all CAN dependent sig-
nals.
Conditions for Clearing the DTC
The DTC will clear when the malfunction has not
occurred for 30 seconds.

of sensors and wiring. TCM obtains the actual engine
speed and throttle position, vehicle speed and
accelerator etc. from ECM via CAN without any

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.
