DTC P1760 OVERRUN CLUTCH SOLENOID VALVE

Diagnostic Procedure

ECS007NP

1.

CHECK GROUND CIRCUIT

1.

Turn ignition switch to OFF position.

2.

Disconnect terminal cord assembly connector in engine compartment.

3.

Check resistance between terminal cord assembly connector
E72 terminal 3 and ground.

Is resistance approx. 20 - 40

Ω?

Yes

>> GO TO 2.

No

>> 1. Remove control valve assembly.

Refer to

AT-402, "REMOVAL"

.

2. Check the following items:

–

Overrun clutch solenoid valve
Refer to

AT-333, "OVERRUN CLUTCH SOLENOID

VALVE"

.

–

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 resistance between terminal cord assembly connector E72 terminal 3 and TCM harness connector
M77 terminal 20.

If OK, check harness for short to ground and short to power.

Is resistance approx 0

Ω?

Yes

>> GO TO 3.

No

>> Repair open circuit or short to ground or short to power in harness or connectors.

3.

CHECK DTC

Perform Diagnostic Trouble Code (DTC) confirmation procedure. Refer to

AT-330, "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.
