P2760 TORQUE CONVERTER
P2760 TORQUE CONVERTER
Description
INFOID:0000000009267999
This DTC is detected when the torque converter clutch solenoid valve is electrically normal but the torque con-
verter clutch does not engage. This is not due to an electrical malfunction (circuit open or shorted), but is
instead due to a mechanical malfunction (sticking of the control valve, malfunction of the solenoid, etc.).

Diagnosis Procedure
INFOID:0000000009268003
1.
CHECK TCM POWER CIRCUIT 1
1. Turn the ignition switch OFF.
2. Disconnect the TCM connector.
3. Check the voltage between the TCM harness connector terminals and ground.
Is the inspection result normal?
YES
>> GO TO 2.
NO
>> GO TO 4.
2.
CHECK TCM POWER CIRCUIT 2
Check the voltage between the TCM harness connector terminals and ground.
Is the inspection result normal?
YES
>> GO TO 3.
NO
>> GO TO 5.
3.
CHECK TCM GROUND CIRCUIT
Check the continuity between TCM harness connector terminals and ground.
Is the inspection result normal?
YES
>> Check intermittent incident. Refer to
GI-45, "Intermittent Incident"
.
NO
>> Repair or replace the malfunctioning parts.
4.
DETECT MALFUNCTION ITEMS (PART 1)
Check the following items:
• Open or short circuit of the harness between battery positive terminal and TCM connectors terminal 45.
• 10A fuse [No.25, fuse block (J/B)]. Refer to
Is the inspection result normal?
YES >> Check
intermittent incident. Refer to
GI-45, "Intermittent Incident"
.
NO
>> Repair or replace the malfunctioning parts.
5.
DETECT MALFUNCTION ITEMS (PART 2)
Check the following items:
• Open or short circuit of the harness between IPDM E/R harness connector terminal 21 and TCM connector
terminals 47, 48.
• Harness open circuit or short circuit between the ignition switch and IPDM E/R. Refer to
