5A-100 AUTOMATIC TRANSMISSION
SSANGYONG MY2002
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.
DIAGNOSTIC TROUBLE CODE (DTC) P1722
VEHICLE TYPE DETERMINATION ERROR
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
Inspect the wiring for poor electrical connections
at the TCM 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 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.
3. If there are any other DTCs like P1714 or P1720,
troubleshoot those prior to P1722.

5D1-4 TRANSFER CASE
COMPONENTS OF THE TOD
TRANSFER CASE SYSTEM
Shift Motor
It locates backside transfer case, which drives rotary
helical cam. When mode select switch changes to 4L,
shift fork is on position for 2.48 : 1 by rotation of helical
cam.
Rear Speed Sensor
A hall effect speed sensor which produces a square
wave. 0 to 5 volts direct current signal in response to
a rotating 30-tooth wheel coupled to the rear propeller
shaft inside the transfer case. Each rotation of the rear
propeller shaft will result in 30 speed sensor pulse.
Front Speed Sensor
A hall effect speed sensor which produces a square
wave. 0 to 5 volts direct current signal in response to
a rotating 30-tooth wheel coupled to the front propeller
shaft inside the transfer case. Each rotation of the front
propeller shaft will result in 30 speed sensor pulse.
Electro-Magnetic Clutch
An electromagnetic clutch used to control the amount
of torque applied to the front propeller shaft.
Position Encoder
A set of 4 gray code switches which provide feedback
to the TCCU indicating the position of the shift motor.
Clutch Pedal Position Switch
A switch on vehicles equipped with a manual transmis-
sion which indicates that the clutch pedal is depressed
Park/Neutral Position Switch
A switch on vehicles equipped with an automatic trans-
mission which indicates that the transmission is in neu-
tral.
4H/4L Switch
A switch selects the desired gear ratio.
DEFINITION OF TERMINOLOGY
Shift Inhibit Speed
The vehicle speed limit, which transfer case shifts, is
disallowed. Vehicle speed is indicated by propeller
shaft speed measurement.
Duty Cycle
Duty cycle is the time the electromagnetic clutch is on
divided by the period in which it is being modulated.
Touch-off
A minimum amount of duty cycle applied to the electro
magnetic clutch.
Front Overrun
A condition where the front propeller shaft is turning at
a rate which is faster than the rear propeller shaft.
Rear Overrun
A condition where the rear propeller shaft is turning at
a rate which is faster than the front propeller shaft.
High Range
The highest (numerically lowest = 1 : 1) gear ratio be-
tween the input and outputs of the transfer case.
Low Range
The lowest (numerically highest = 2.48 : 1) gear ratio
between the input and outputs of the transfer case.
OPERATION OF THE TOD
TRANSFER CASE SYSTEM
Initial Operation of TOD Control Unit
When ignition switch is turned to ON, 4WD LOW and
4WD CHECK lamp illuminates for 0.6 second to check
bulb in instrument panel, then perform diagnosis of
system. Refer to “Self-Diagnosis Test” in this section.
Electric Shift System Operation
The electric shift system is responsible for changing
the transfer case gear ratio by controlling the electric
shift motor. The TCCU monitors the 4H/4L switch, park/
neutral position switch, speed sensors, position
encoder, and ignition switch.
A range change is initiated when:
The 4H/4L switch is changed from 4H to 4L or from
4L to 4H.
The motor position (as indicated by the position
encoder) does not match the 4H/4L switch
immediately after the ignition is turned on.
Shift Criteria
When a range change is initiated a diagnostic test will
be completed on the motor, speed sensors, and
position encoder. If the diagnostic test fails, the shift
will not be attempted. If all components are operating
properly, the TCCU will attempt a range change after
the following shift criteria are met:
The transmission is in neutral for 2 seconds after
the shift is requested.
Both propeller shaft speeds are below 87 rpm (2580
pulses/minute). If the transmission is taken out of
neutral before 2 seconds has passed, or either
propeller shaft speed increases above the limit, the
shift will be suspended and the 4L indicator will
continue to blink until the criteria are met again or
the 4H/4L switch is returned to the original position.
Range Change
When the shift criteria are met, the motor is rotated in
the appropriate direction (as determined by the selector
switch) until one of the following occurs:

TRANSFER CASE 5D1-5
SSANGYONG MY2002
The motor reaches its destination.
The motor is on for 5 seconds without reaching its
destination. The shift has failed and the TCCU will
respond as default mode.
A fault occurs with either the motor or position
encoder. Refer to the diagnosis requirement.
When the motor is energized, the Ignition, 4H/4L
switch, propeller shaft speeds, and transmission
neutral inputs are ignored.
Indicator Function
Once a range change has been initiated the 4WD LOW
indicator will begin to blink at a rate of 0.3 seconds
on, 0.3 seconds off until the shift is completed or
canceled. If a successful shift has been completed,
the 4WD LOW indicator will be illuminated if the motor
is in low range and it will be turned off if the motor is in
high range.
4WD LOW indicator illuminates as below figure.
KAA5D000
TODTM System Operation
The TODTM System is responsible for distributing torque
between the front and rear axles. The TCCU monitors
the propeller shaft speeds, operating range (high/low),
and ABS activity and then applies a calculated amount
of torque to the front axle by pulse width modulating
(PWM) the current applied to the electromagnetic clutch
(EMC).
Touch-off Torque
The minimum EMC duty cycle is based on the vehicle
speed and throttle position. The TCCU receives the
throttle position (TP) sensor signal from the engine con
trol module (ECM) through CAN bus line.
Wheel Slip Detection and Control
The TCCU continuously monitors the front and rear pro-
peller shaft speeds to detect wheel slip.
When wheel slip is detected the TCCU controls the
EMC duty cycles as necessary until the wheel slip is
reduced below the allowable limit. The EMC duty cycle
will then be reduced to the touch-off value.Brake/ABS Strategy
When the ABS System is active, the EMC duty cycle
is set to a fixed duty cycle (30%) to aid in braking
without counteracting the ABS System.
4L Strategy
When the system is operating in 4WD low range, the
TCCU continues TOD
TM operation provided that the pro
peller shaft speed is below 175 rpm (5220 pulses/min-
ute). When the speed increases above 175 rpm, the
EMC duty cycle is set to the maximum value (88 %)
which applies the maximum available torque to the front
axle.
Position Encoder
The position encoder is used by the TCCU to determine
the position of the shift motor. Each motor position is
identified by a position code as shown.

Notice:
All other position codes are invalid
Position input : open circuit (> 4.5V) = 1
Position input : Shorted to speed/position return
(< 0.5V) = 0
Position Sensor Interpretation
1. When the module powers up, it will read the position
sensor and the 4H/4L switch input and respond to
the possible codes as following tables.
2. A command to shift will only be acted upon if the
TCCU is reading a valid code at the time the com-
mand to shift is made.
3. After a shift has started, the TCCU will power the
shift motor until the code for the requested position
is read. If an invalid code is read, the TCCU will go
into a default mode.
4. During a shift attempt, the shift motor will be ener-
gized for a maximum of 5 second

SYSTEM
The base heater system is designed to provide heating,
ventilation, windshield defrosting, side wind defogging
and rear seat area.
The heater and fan assembly blower regulates the air-
flow from the air inlet for further processing and distribu-
tion.
The heater core transfers the heater from the engine
coolant to the inlet air.
The temperature door regulates the amount of the air
that passes through the heater core. The temperature
door also controls the temperature of the air by control-
ling mix of heated air with the ambient air.
The mode door regulates the flow and distribution of
the processed air to the heater ducts and to the defroster
ducts.
The console mounted heating and ventilation control
panel contains one rotary control knob, one sliding con-
trol lever and six push control knobs, which operate as
follows:
