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.
Test Description
The number(s) below refer to the step number(s) on
the Diagnostic Table.
Step
Perform a Transmission Control Module (TCM) System
Check.
1
Is the check performed?
1. Install the scan tool.
2. Turn the ignition ON, with the engine OFF.
3. Record and then clear DTCs.
2
4. Operate the vehicle within the conditions for
setting this DTC as specified in the text.
Does the scan tool display P1739?
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
3
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 open circuit on the solenoids side of
STET illuminate?
1. Remove the pump assembly. Refer to the Pump in
this section.
2. Check the wiring harness from 10-way transmission
4
connector to contact point attached onto the
transmission case for an open or short to positive
and repair as necessary.
Is a repair necessary?
Check the wiring harness from contact point attached
onto the transmission case to S7 for an open or short
5
to positive and repair as necessary.
Is a repair necessary?
Check the S7 ground circuit for an open and repair as
necessary.
6
Is a repair necessary?
Using a Digital Volt Meter (DVM), measure the
resistance between S7 terminal A and B.
7
Is the resistance within the specified value?
Replace the S7.
8
Is the action complete?

3. Checks if the S7 circuit in the transmission is mal-
functioning.
4. Check cable in the transmission for open / short.
If the problem is found in the wiring harness from
10-way transmission connector to contact point
attached onto the transmission case, repair it with
removing the valve cover. Refer to the
Transmission in this section.
7. Check resistance between S7 terminal A and B.
Standard value is 22 - 30 Ω.
10. Check connections of other connectors.
