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.

5A-118 AUTOMATIC TRANSMISSION
SSANGYONG MY2002
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
and band regulator, thereby controlling the shift
pressure.
The solenoid 5 is attached to the valve body within
the transmission. Voltage is supplied directly to the
solenoid through the Transmission Control Module
(TCM).
The DTC P1737 sets when the solenoid 5 (S5) circuit
is open or the switched leg of the solenoid 5 is shorted
to battery positive. The solenoid 5‘s driver Integrated
Chip (IC) status indicates a fauty circuit.
Conditions for Setting the DTC
DTCs P1717 and P1718 are not set.
The solenoid 5‘s driver Integrated Chip (IC) status
indicates a faulty circuit. This condition must be
continuously present for 60 milliseconds.
The measured S5 current is greater than 100 mA
below its expected lower limit.
Action Taken When the DTC Sets
Solenoid 5 is disabled (always OFF).
The shift quality is degraded.
DIAGNOSTIC TROUBLE CODE (DTC) P1737
SOLENOID 5 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
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.
