DTC P1760 OVERRUN CLUTCH SOLENOID VALVEPFP:31940
DescriptionECS007PH
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 PROCEDURE” 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 malfunction 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”).
5. If DTC is detected, go to AT- 1 9 0 , "
Diagnostic Procedure" .
With GST
Follow the procedure “With CONSULT-II”.

DTC P1760 OVERRUN CLUTCH SOLENOID VALVE
Diagnostic Procedure
ECS007PJ
1. CHECK VALVE RESISTANCE
1. Turn ignition switch to “OFF” position.
2. Disconnect terminal cord assembly connector in engine compartment.
3. Check resistance between terminal 3 and ground.
OK or NG
OK >> GO TO 2
NG >> 1. Remove control valve assembly. Refer to AT- 4 0 6 ,
"Control Valve Assembly and Accumulators" .
2. Check the following items:
–Overrun clutch solenoid valve
Refer to AT-191, "
Component Inspection" .
–Harness of terminal cord assembly for short or open
2. CHECK POWER SOURCE CIRCUIT
1. Turn ignition switch to “OFF” position.
2. Disconnect TCM harness connector.
3. Check continuity between terminal 3 and TCM harness connector terminal 20.
If OK, check harness for short to ground and short to power.
4. Reinstall any part removed.
OK or NG
OK >> GO TO 3
NG >> Repair open circuit or short to ground or short to power
in harness or connectors.
3. CHECK DTC
Perform AT-188, "
DIAGNOSTIC TROUBLE CODE (DTC) CONFIRMATION PROCEDURE" .
OK or NG
OK >>INSPECTION END
NG >> 1. Perform TCM input/output signal inspection.
2. If NG, recheck TCM pin terminals for damage or loose connection with harness connector. Resistance: 20 - 30Ω

DTC U1000 CAN COMMUNICATION LINE
DTC U1000 CAN COMMUNICATION LINE
PFP:31940
DescriptionECS007PL
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
TCM TERMINALS AND REFERENCE VALUE
Remarks: Specification data are reference values.
*: This terminal is connected to the ECM.
On Board Diagnosis LogicECS007PM
**:A/T COMMLINE means DTC U1000 CAN communication line.
DTC Confirmation ProcedureECS007PN
After the repair, perform the following procedure to confirm the malfunction is eliminated.
WITH CONSULT-II
1. Turn ignition switch “ON”.
2. Select “DATA MONITOR” mode for “ENGINE” with CONSULT-II.
3. Wait at least 6 seconds or start engine and wait for at least 6
seconds.
4. If DTC is detected, go to AT- 1 9 4 , "
Diagnostic Procedure" .
WITHOUT CONSULT-II
1. Turn ignition switch “ON”.
2. Wait at least 6 seconds or start engine and wait at least 6 sec-
onds.
3. Perform self-diagnosis.
Refer to AT- 5 1 , "
TCM SELF-DIAGNOSTIC PROCEDURE (NO
TOOLS)" .
