5A-146 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, there by 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 P1745 sets when the Solenoid 5 (S5) circuit
is shorted to ground. The solenoid 5’s driver
Integrated Chip (IC) status indicates a faulty circuit.
Conditions for Setting the DTC
DTCs P1717 and P1718 are not set.
S5 is ON.
The solenoid 5’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
Solenoid 5 is disabled (always OFF)
The shift quality is degraded.
Conditions for Clearing the DTC
The DTC will clear when the malfunction has not
occurred after ignition cycle.
DIAGNOSTIC TROUBLE CODE (DTC) P1745
SOLENOID 5 CIRCUIT SHORT
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 a short circuit to ground
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 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.

Circuit Description
The solenoid 6 is a normally open ON/OFF type sole-
noid that is used to set the high/ low level of line pres-
sure.
The solenoid 6 (S6) OFF gives high pressure and the
S6 is attached to the valve body within the
transmission. Voltage is supplied directly to the
solenoid through the Transmission Control Module
(TCM).
The DTC P1746 sets when the Solenoid 6 (S6) circuit
is shorted to ground. The solenoid 6’s driver
Integrated Chip (IC) status indicates a faulty circuit.
Conditions for Setting the DTC
DTCs P1717 and P1718 are not set.
S6 is ON.
The solenoid 6’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 6 is disabled (OFF) resulting in high
line pressure being applied continuously.
Conditions for Clearing the DTC
The DTC will clear when the malfunction has not
occurred after ignition cycle.
DIAGNOSTIC TROUBLE CODE (DTC) P1746
SOLENOID 6 CIRCUIT SHORT
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 6 is turned OFF/
ON by a very small (4 millisecond) pulses. 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 a short circuit to ground
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.
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 inside the insulation.
