•
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.

4. Operate the vehicle within the conditions for
setting this DTC as specified in the text.
Does the scan tool display P1734?
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 2 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 harness from 10-way transmission

connector to Solenoid 2 (S2) on the valve body for an
open or short to positive and repair as necessary.
Is a repair necessary?
