5A-98 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 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.
DIAGNOSTIC TROUBLE CODE (DTC) P1721
THROTTLE 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 throttle 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 throttle
position sensor on the ECM side.
4. Check for a poor connection at the ECM and TCM
connectors.

Circuit Description
The Electrically Erasable Programmable Read-Only
Memory (EEPROM) is a permanent memory chip that
is physically soldered within the Transmission Control
Module (TCM) The EEPROM contains the program and
the calibration information required for the transmission
and transmission diagnostics operation.
The DTC P1722 sets when TCM is unable to determine
the vehicle type from EEPROM or CAN. CAN vehicle
type information is in error or unavailable in time.
By definition, there must by on EEPROM fault (P1720)
or an EEPROM vehicle code error (P1714) to cause the
TCM to try and determine the vehicle code by other
means.
The DTC P1722 is a reflection of the significance of
the problem caused by the other error.
Conditions for Setting the DTC
EEPROM information is in error or unreliable.
Vehicle type information on the CAN is not present
or in error.
The above condition exists for 1 second after power
up.
Action Taken When the DTC Sets
If CAN is detected, OBD N32D VIN is selected. Or
If CAN is not detected, P29 STi VIN is selected.
Shift quality may be degraded.

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.

Circuit Description
The solenoid 5 is a variable force solenoid that ramps
the pressure during the gear changes and solenoid
switching, to enhance the transmission shift quality.
This solenoid provides the signal pressure to the clutch

the transmission. Voltage is supplied directly to the
solenoid through the Transmission Control Module
(TCM).

Diagnostic Aids
The current to solenoid 5 was outside acceptable
limits.
This fault results from a mismatch between the cur-
rent set point for solenoid 5 and the current
measured by the feedback within the TCM.
Typical causes would be an open circuit or short
circuit to power in the wiring to, from or within the
solenoid.
It is also possible that there has been a fault in the
solenoid output circuit. But if this is the cause, the
fault should be continually present.
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 wire in-side the insulation.
