DIAGNOSTIC TROUBLE CODE (DTC) P1747
SOLENOID 7 CIRCUIT SHORT
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 is at-
tached to the pump body within the transmission. Volt-
age is supplied directly to the solenoid through the
Transmission Control Module (TCM).
The DTC P1747 sets when the solenoid 7, Torque
Converter Clutch Solenoid, circuit is shorted to ground.
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 ON.
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 continuously.
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 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 tobare metal or other wiring. Inspect
for broken wire inside the insulation.

Standard value is 22 - 30 Ω.
10. Check connections of other connectors.
- Go to Step 15 Go to Step 7 1Perform a Transmission Control Module (TCM) System
Check.
Is the check performed?
1. Install the scan tool.
2. Turn the ignition ON, with the engine OFF.
3. Record and then clear DTCs.
4. Operate the vehicle within the conditions for
setting this DTC as specified in the text.
Does the scan tool display P1747?
1. Turn the ignition OFF.
2. Disconnect the 10-way transmission connector.
(additional DTCs will set)
3. Connect Solenoid/Thermistor Electrical Tester
(STET) to the 10-way transmission connector of
transmission side and to the good ground.
4. Turn the mode knob of STET to 7 and push the red
button.
Does the bulb of close circuit on the solenoids side of
STET illuminate?
1. Remove the pump assembly. Refer to the Pump in
this section.
2. With a test light connected to B+, probe the wiring
harness from 10-way transmission connector to
contact point attached onto the transmission case.
Does the test light illuminate?
Repair the short to ground in the wiring harness.
Is the repair complete?
With a test light connected to B+, probe the wiring
harness from contact point attached onto the trans-
mission case to S7.
Does the test light illuminate?
Using a Digital Volt Meter (DVM), measure the
resistance between S7 terminal A and B.
Is the resistance within the specified value?
Replace the S7.
Is the action complete?
1. Disconnect the TCM connector A.
2. With a test light connected to B+, probe the wiring
harness from 10-way transmission connector
terminal 7 to TCM terminal A9.
Does the test light illuminate?

REBUILD WARNINGS
Prior to rebuilding a transmission system, the following warnings are to be noted.
Ensure that, before replacing a transmission the cooler lines are flushed out to remove any debris. This can
be done by applying compressed air to the rear cooler line forcing oil and any contaminants out of the front
cooler line.
The cooler flow should be checked after the transmission has been fitted. With the front cooler line connected
and the rear line run into a suitable container, measure the flow over 15 seconds with the vehicle idling in park.
The flow rate should exceed 1 liter in 15 seconds.
Be wary of any situation where water enters the transmission. This may result in fluid foaming and leaking
through the breather.
Ensure that both earth straps (one at the battery terminal and one on the vehicle body) are connected in the
vehicle before connecting the positive side of the battery.
Follow the throttle position calibration procedure in this manual if the engine control module/ transmission
control module (ECM/TCM) is swapped.
