5A-70 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 position etc. from ECM via CAN without
any additional sensors.
The DTC P1703 sets when the engine speed signal via
CAN is out of range or not feasible: The engine speed
signal is greater than 7000 rpm or less than 0 rpm, or
the indicated engine speed is low while other signals
indicate the car is moving (i.e. the vehicle speed has
increased more than 125 rpm).
Conditions for Setting the DTC
Immediately upon the test indicating malfunction
as follows.
The engine speed signal is greater than 7000 rpm
or less than 0 rpm under the precondition that DTC
P1719 is not set.
The indicated engine speed is low while other signals
indicate the car is moving, i.e. the vehicle speed
has increased more than 125 rpm under the following
precondition;
- Driving gear is selected.
- The applied throttle is greater than 5 %.
- The engine speed is less than 550 rpm.
- DTCs P0706, P0707, P0708, P1704, P1719 and
1721 are not set.
Action Taken When the DTC Sets
Fault detection of some other signals will not pos-
sible.
DIAGNOSTIC TROUBLE CODE (DTC) P1703
ENGINE SPEED SIGNAL ERROR
Conditions for Clearing the DTC
The DTC will clear after 30 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
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 engine speed
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 engine
speed sensor on the ECM side.
4. Check for a poor connection at the ECM and TCM
connectors.

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 position etc. from ECM via CAN without
any additional sensors.
The DTC P1704 sets when the indicated drive shaft
speed signal via CAN is out of range or not feasible or
a shaft speed of 0 is present while other signals indicate
the vehicle is being driven.
Conditions for Setting the DTC
Immediately upon the test indicating malfunction
as follows.
The shaft speed signal is greater than 9000 rpm or
less than 0 rpm under the precondition that DTC
P1719 is not set.
The shaft speed indicates 0 rpm while all other sig-
nals indicate the car is moving under the following
precondition;
- Driving gear is selected.
- The transmission range sensor has not recently
changed state.
- The engine speed is greater than 2800 rpm.
- DTCs P0706, P0707, P0708, P1703 and P1719
are not set.
The shaft speed has dropped from above 2100 rpm
to 0 rpm within 20 ms.
DIAGNOSTIC TROUBLE CODE (DTC) P1704
SHAFT SPEED SIGNAL ERROR
Action Taken When the DTC Sets
All skip downshifts disabled and fourth gear will
be in-hibited.
The torque converter will be unlocked at all times.
Gears are selected by the shift control lever but all
downshifts are inhibited by engine speed limits to
prevent over-revving.
D position selects 3rd gear.
1st and 2nd gears can be manually selected.
Conditions for Clearing the DTC
The DTC will clear when the malfunction has not
occurred for 30 seconds and a non-zero speed is
detected.
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.

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.

5A-90 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 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.
