SSANGYONG KORANDO 1997 Service Repair Manual

5A-126 AUTOMATIC TRANSMISSION
SSANGYONG MY2002
Circuit Description
The solenoid 7 is a normally open ON/OFF type sole-
noid that is used to control the application of the
Torque Converter Clutch (TCC).
The Solenoid 7 (S7) ON activates the TCC and the S7
is attached to the pump body within the transmission.
Voltage is supplied directly to the solenoid through
the Transmission Control Module (TCM).
The DTC P1739 sets when the solenoid 7, Torque Con-
verter Clutch Solenoid, circuit is open or the switched
leg of the solenoid 7 is shorted to battery positive.
The solenoid 7's driver Integrated Chip (IC) status
indicates a faulty circuit.
Conditions for Setting the DTC
DTCs P1717 and P1718 are not set.
S7 is OFF.
S3 is OFF.
The solenoid 7'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 7 is always disabled (OFF) resulting
in the TCC being unlocked always.
DIAGNOSTIC TROUBLE CODE (DTC) P1739
SOLENOID 7 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 7 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 recorede.
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.
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.
