DTC P1737 Solenoid 5 Circuit Open

•

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. Checks if the S5 circuit in the transmission is mal-

functioning.

4. Check cable in the transmission for open / short.

6. Check resistance between S5 terminal A and B.

Standard value is 3.6 - 5.5

Ω

9. Check connections of other connectors

Perform 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 P1737?
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.

4. Turn the mode knob of STET to 5 and push the red

button.

Does the bulb of open circuit on the solenoids side of
STET illuminate?
1. Remove the valve cover. Refer to the Transmission

in this section.

2. Check the wiring harnesses from 10-way trans

mission connector to Solenoid 5 (S5) on the valve
body for an open or short to positive and repair as
necessary.

Is a repair complete?
Using a Digital Volt Meter (DVM), measure the
resistance between S5 terminal A and B.
Is the resistance within the specified value?
Replace the S5.
Is the action complete?
1. Disconnect the TCM connector A.
2. Check the wiring harness from 10-way transmis-

sion connector terminal 5 to TCM terminal A1 for an
open or short to battery and repair as necessary.

Is a repair necessary?
Check the wiring harness from 10-way transmission
connector terminal 8 to TCM terminal A7 for an open
and repair as necessary.
Is a repair necessary?

Check for a poor connection at the 10-way transmission
connector and TCM connector and repair the malfunc-
tioning terminals as necessary.
Is a repair necessary?
1. Turn the ignition OFF.
2. Replace the TCM.
Is the action complete?
1. Using the scan tool, clear the DTCs.
2. Road test the vehicle within the conditions for

setting this DTC as specified in the text.

Does the scan tool indicate that this diagnostic has
run and passed?

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
S 6 i s a t t a c h e d t o t h e v a l v e b o d y w i t h i n t h e
transmission. Voltage is supplied directly to the
solenoid through the Transmission Control Module
(TCM).

The DTC P1738 sets when the solenoid 6 circuit is
open or the switched leg of the solenoid 6 is shorted
to battery positive. 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 OFF.

•

S4 is OFF.

•

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.

DIAGNOSTIC TROUBLE CODE (DTC) P1738

SOLENOID 6 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 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 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.
