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.

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.
DIAGNOSTIC TROUBLE CODE (DTC) P1733
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.
