VALVE RELAY CIRCUIT FAULT
KAA4F210
Circuit Description
When the ABS is active, the valve relay provides voltage
to actuate the solenoid valves. The valves do not use
this voltage unless the ABS control module provides
the ground for each solenoid coil.
DTC 12 will set if the valve relay voltage is low or if the
relay supply line is at 12 volts when the ABS control
module is not requesting it. This DTC will also set if the
ABS control module detects three or more solenoid
valve circuits are open or shorted during the self-test.
Diagnosis
This procedure checks whether there is a poor ground
connection for the electronic brake control module
(EBCM).Cause(s)
A connector terminal is corroded.
The wiring harness is damaged.
The ground terminal is not conducting properly.
The valve relay is defective.
The EBCM is defective.
Fail Action
ABS/TCS is disabled, and the ABS warning lamp is
turned ON for the remainder of the ignition cycle. If the
failure is intermittent, the control module will enable
the system at the next ignition cycle and set a history
DTC 12.
Diagnostic Aids
It is very important to perform a thorough inspection of
the wiring and the connectors. Failure to do so may re
sult in misdiagnosis, causing part replacement with the
reappearance of the malfunction.

DIAGNOSIS
BASIC KNOWLEDGE REQUIRED
You must be familliar with some basic electronics to
use this section of the Service Manual. They will help
you to follow diagnostic procedures.
Notice: Lack of the basic knowledge of this transmis-
sion when performing diagnostic procedures could re-
sult in incorrect diagnostic performance or damage to
transmission components. Do not, under any circum-
stances, attempt to diagnose a transmission problem
without this basic knowledge.
Notice: If a wire is probed with a sharp instrument
and not properly sealed afterward, the wire will corrode
and an open circuit will result.
Diagnostic test probes are now available that allow
you to probe individual wires without leaving the wire
open to the environment. These probe devices are
inexpensive and easy to install, and they permanently
seal the wire from corrosion.
Special Tools
You should be able to use a Digital Volt Meter (DVM),
a circuit tester, jumper wires or leads and a line
pressure gauge set. The functional check procedure
is designed to verify the correct operation of electronic
components in the transmission. This will eliminate the
unnecessary removal of transmission components.
FUNCTIONAL CHECK
PROCEDURE
Begin with the Functional Check Procedure which pro-
vides a general outline of how to diagnose automatic
transmission. The following functional check procedure
will indicate the proper path of diagnosing the transmis-
sion by describing the basic checks and then referenc-
ing the locations of the specific checks.
Check the fluid level according to the Fluid Level
Service Procedure.
Check the transmission fluid leak.
Check if the transmission fluid is not burnt by smell.
Notice: The specific fluid used in this transmission
turns brown during normal operation. Brown fluid
does not indicate a transmission fault.
Ensure that the transmission is not in Limp Home
Mode (LHM).
Check the battery terminals and the earth connec-
tions for corrosion or looseness.
Check that the cooler flow is not restricted.
Check all electrical plug connections for tightness.
Use on-board diagnostic tool or a scan tool to see
if any transmission trouble codes have been set.
DIAGNOSTIC INFORMATION AND PROCEDURES
Refer to the appropriate “Diagnostic Trouble Code
(DTC)” information and repair the vehicle as
directed. After repairing the vehicle, perform the
road test and verify that the code has not set again.
Perform the Electrical/Garage Shift Tests.
Perform the Road Test Procedure in this section.
Inspect the oil and check for metal or other contami-
nants in the oil pan.
TRANSMISSION FLUID LEVEL
SERVICE PROCEDURE
This procedure is to be used when checking a concern
with the fluid level in a vehicle. A low fluid level will
result in slipping and loss of drive/ reverse or delay on
engagement of drive/ reverse when the vehicle is cold.
The vehicle is first checked for transmission diagnostic
messages on the scan tool. If the oil level is low, it is
possible to register a vehicle speed signal fault.
The vehicle is to be test driven to determine if there is
an abnormal delay when selecting drive or reverse, or
loss of drive. One symptom of low fluid level is a
momentary loss of drive when driving the vehicle around
a corner. Also when the transmission fluid level is low,
a loss of drive may occur when the transmission fluid
temperature is low.
If there is no loss of drive when the vehicle is driven
warm and a vehicle speed signal fault is registered,
then fluid should be added to the transmission.
When adding or changing transmission fluid use only
Castrol TQ 95 automatic transmission fluid. The use of
incorrect fluid will cause the performance and durability
of the transmission to be severely degraded.
Fluid Level Diagnosis procedure
1. If the vehicle is at operating temperature allow the
vehicle to cool down for two hours, but no greater
than four hours. Or if the vehicle is at cool status,
start the engine and allow the engine to idle for
approximately 5 minutes or, if possible, drive the
vehicle for a few kilometers. This will allow the
transmission to be within the correct temperature
range. Transmission fluid level should be checked
at temperature 50 - 60 °C (82 - 140 °F).
Caution: Removal of the fluid filler plug when
the transmission fluid is hot may cause injury if
fluid drains from the filler hole.
2. With the brake pedal pressed, move the gear shift
control lever through the gear ranges, pausing a
few seconds in each range. Return the gear shift
control lever to P (Park). Turn the engine OFF.
3. Park the vehicle on a hoist, inspection pit or similar
raised level surface. The vehicle must be control
level to obtain a correct fluid level measurement.
5A-62 AUTOMATIC TRANSMISSION
SSANGYONG MY2002
Circuit Description
The Transmission Fluid Temperature (TFT) sensor is a
thermistor located in the solenoid wiring loom within
the valve body of the transmission. This sensor is a
typical Negative Temperature Coefficient (NTC) resistor
with low temperatures producing a high resistance and
high temperatures producing a low resistance.
If the transmission fluid temperature exceeds 135 °C
(275 °F), the TCM will impose converter lock-up at lower
vehicle speeds. Favour a lower gear to increase engine
speed, and in some vehicles flashes the mode indicator
lamp. This results in maximum oil flow through the exter-
nal oil cooler and eliminates slippage in the torque
converter. Both these actions combine to reduce the
oil temperature in the transmission.
The DTC P0710 sets when the TFT sensor signal is not
feasible.
Conditions for Setting the DTC
Transmission fluid temperature sensor signal is
greater than 4.88 volts (immediate detection).
Transmission fluid temperature sensor signal is less
than 0.21 volts (immediate detection).
Transmission temperature has not changed by 2 °C
in 15 minutes since ignition on and temperature is
less than 20 °C or greater than 125 °C.
Action Taken When the DTC Sets
Transmission fluid temperature is assumed to be
120 °C (248 °F).
All shifts will be firm until the transmission has
warmed up because a high transmission fluid
temperature is assumed.

TRANSMISSION FLUID TEMPERATURE SENSOR CIRCUIT
MALFUNCTION
Conditions for Clearing the DTC
The DTC will clear when the malfunction has not oc
curred 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 trans-
mission fluid temperature input terminals has been
outside acceptable levels.
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 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 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.
Test Description
The number(s) below refer to the step number(s) on
the Diagnostic Table.
5. This step simulates a DTC P0710 condition. If the
scan tool displays the specified value, the TFT
sensor signal circuit and the TCM are OK.

UNIT REPAIR
REBUILD WARNINGS
Prior to rebuilding a transmission system, the following warnings are to be noted.
Ensure that, before replacing a transmission the cooler lines are flushed out to remove any debris. This can
be done by applying compressed air to the rear cooler line forcing oil and any contaminants out of the front
cooler line.
The cooler flow should be checked after the transmission has been fitted. With the front cooler line connected
and the rear line run into a suitable container, measure the flow over 15 seconds with the vehicle idling in park.
The flow rate should exceed 1 liter in 15 seconds.
Be wary of any situation where water enters the transmission. This may result in fluid foaming and leaking
through the breather.
Ensure that both earth straps (one at the battery terminal and one on the vehicle body) are connected in the
vehicle before connecting the positive side of the battery.
Follow the throttle position calibration procedure in this manual if the engine control module/ transmission
control module (ECM/TCM) is swapped.

2. Carefully assemble the oil filter to the valve body.
The spigot must not lean on one side while being
fitted.
3. Secure the oil filter assembly with the retainer.
4. Check that the magnet is located in the dimple in
the corner of the oil pan.
5. Assemble the gasket on the pan lip. The gasket
must be free of any distortion when installed. 25. Check the alignment of the detent roller and the
manual lever quadrant.
26. Connect the solenoid wiring as detailed below:
Solenoid 1 - red
Solenoid 2 - bIue
Solenoid 3 - yellow
Solenoid 4 - orange
Solenoid 5 - green
Solenoid 6 - violet
Notice: All hardware must be correctly installed and
torqued to specification.
Oil Filter and Pan Assembly
Notice:
Replace the filter whenever rebuilding a
transmission where a significant amount of
mechanical damage has occurred.
To aid the assembly of the pan gasket, use a small
amount of Vaseline at the pan/gasket interface. This
ensures that the gasket remains on the pan ridge.
Do not over torque pan bolts as this may distort
the pan and cause leaks.
Ensure that the internal line pressure plus in the
valve body is fitted.
1. Lubricate the oil filter sealing ring with automatic
transmission fluid.
