DTC P1760 OVERRUN CLUTCH SOLENOID VALVEPFP:31940
DescriptionECS004S9
The overrun clutch solenoid valve is activated by the TCM in
response to signals sent from the inhibitor switch, overdrive control
switch, vehicle speed and throttle position sensors. The overrun
clutch operation will then be controlled.

DIAGNOSTIC TROUBLE CODE (DTC) CONFIRMATION PROCEDURE
CAUTION:
Always drive vehicle at a safe speed.
NOTE:
If “DIAGNOSTIC TROUBLE CODE CONFIRMATION PROCE-
DURE” has been previously conducted, always turn ignition
switch “OFF” and wait at least 5 seconds before conducting the
next test.
TESTING CONDITION:
Always drive vehicle on a level road to improve accuracy of
test.
After the repair, perform the following procedure to confirm the mal-
function is eliminated.
With CONSULT-II
1. Turn ignition switch “ON” and select “DATA MONITOR” mode for
“ENGINE” with CONSULT-II.
2. Start engine.
3. Accelerate vehicle to a speed of more than 10 km/h (6 MPH)
with “D” position (OD “ON”).
4. Release accelerator pedal completely with “D” position (OD “OFF”).
With GST
Follow the procedure “With CONSULT-II”.
