P1760 OVERRUN CLUTCH SOLENOID
P1760 OVERRUN CLUTCH SOLENOID
DescriptionINFOID:0000000005928202
The overrun clutch solenoid valve is activated by the TCM in response to signals sent from the transmission
range switch, overdrive control switch, vehicle speed and ECM (throttle opening). The overrun clutch opera-
tion will then be controlled.
CONSULT-III Reference Value in Data Monitor ModeINFOID:0000000005928203
On Board Diagn osis LogicINFOID:0000000005928204
• This is an OBD-II self-diagnostic item.
• Diagnostic trouble code “P1760 OVER CLUTCH SOLENOID ” with CONSULT-III or 6th judgement flicker
without CONSULT-III is detected when TCM detects an improper voltage drop when it tries to operate sole-
noid valve.
Possible CauseINFOID:0000000005928205
• Harness or connector
(The solenoid circuit is open or shorted.)
• Overrun clutch solenoid valve
DTC Confirmation ProcedureINFOID:0000000005928206
CAUTION:
• Always drive vehicle at a safe speed.
• If performing this “DTC Confirmation Procedure” again, always turn ignition switch OFF and wait at
least 10 seconds before continuing.
After the repair, perform the following proc edure to confirm the malfunction is eliminated.
WITH CONSULT-III
1. Turn ignition switch ON and select “DATA MONI TOR” mode for “TRANSMISSION” with CONSULT-III.
2. Touch “START”.
3. Start engine.
4. Accelerate vehicle to a speed of more t han 10 km/h (6 MPH) with “D” position (OD ON).
5. Release accelerator pedal completely with “D” position (OD OFF).
6. If the check result is NG, go to AT-150, "
Diagnosis Procedure".
WITH GST
Follow the procedure “WITH CONSULT-III”.
WITHOUT CONSULT-III
1. Start engine.
2. Drive vehicle under the following conditions:
Selector lever position: “D” position (OD ON)
Vehicle speed: Higher than 10 km/h (6 MPH)
3. Perform self-diagnosis. Refer to AT-82, "
Diagnosis Procedure without CONSULT-III" .
4. If the check result is NG, go to AT-150, "
Diagnosis Procedure" .
