Circuit Description
The driving mode selector switch is located on the
center console and allows the driver to select the
driving mode.
When NORMAL mode is selected upshifts will occur
to maximize fuel economy. When POWER mode is se-
lected, upshifts will occur to give maximum
performance and the POWER mode indicator light is
switched ON.
When WINTER mode is selected, starting in second
gear is facilitated, the WINTER mode indicator light is
switched ON and the POWER mode indicator light is
switched OFF.
The DTC P0790 sets when an intermittent connection
in the mode selector switch (mode switch) circuit has
been detected. The mode switch input is rapidly
changing states. 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
All shifts will occur as if the mode is set to NORMAL.
The mode indicator will always be OFF indicating
that NORMAL mode is selected.
The mode indicator will not respond to the changes
in switch setting.
DIAGNOSTIC TROUBLE CODE (DTC) P0790
NORMAL/PERFORMANCE 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.
Test Description
The number(s) below refer to the step number(s) on
the Diagnostic Table.
3. Check mode switch signal circuit for an
intermittent open / short
5. Check mode switch ground circuit for an
intermittent open / short
8. Check mode switch feed circuit for an intermittent
open / short

Circuit Description
The battery voltage monitoring input is connected to
the positive side of the battery. This signal is taken
from the main supply to the TCM.
If the battery voltage is greater than 16.5 V, DTC P1709
will be set and the transmission will adopt limp home
mode and all solenoids are turned OFF.
Conditions for Setting the DTC
The indicated supply voltage is greater than 16.5 V.
The malfunction triggers immediately after this
condition exists.
Action Taken When the DTC Sets
All solenoids are turned OFF while the high battery
voltage condition is detected.
The transmission goes into Limp Home Mode (LHM).
Conditions for Clearing the DTC
The DTC will clear when the malfunction has not
occurred for 30 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 TROUBLE CODE (DTC) P1709
TCM SUPPLY VOLTAGE HIGH
Diagnostic Aids
The voltage measured by the TCM corresponding
to the battery supply voltage has been outside the
range of the maximum operating voltage of 16.5 V.
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.
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 generator is malfunctioning under
load conditions.
5. Check connection of other connectors.

5A-102 AUTOMATIC TRANSMISSION
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.
