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.).

DTC DETECTION LOGIC

DTC REPRODUCTION PROCEDURE

CAUTION:

Be careful of the driving speed.

1.

PREPARATION BEFORE WORK

If another “DTC CONFIRMATION PROCEDURE” occurs just before, turn ignition switch OFF and wait for at

least 10 seconds, then perform the next test.

>> GO TO 2.

2.

CHECK DTC DETECTION

1. Drive the vehicle.

2. Maintain the following conditions for 40 seconds or more.

3. Stop the vehicle.

4. Check the first trip DTC.
Is “P2760” detected?

YES

>> Go to 

TM-214, "Diagnosis Procedure"

.

NO

>> INSPECTION END

Diagnosis Procedure

INFOID:0000000009268001

1.

CHECK LINE PRESSURE

Perform line pressure test. Refer to 

TM-130, "Work Procedure"

.

Is the check result normal?

YES 

>> GO TO 2.

NO

>> Repair or replace the malfunction items.

2.

CHECK TORQUE CONVERTER CLUTCH SOLENOID VALVE

1. Turn the ignition switch OFF.

2. Disconnect the A/T unit connector.

3. Check the torque converter clutch solenoid valve. Refer to 

TM-215, "Component Inspection (Torque Con-

verter Clutch Solenoid Valve)"

.

Component Inspection (Torque Converter Clutch Solenoid Valve)

INFOID:0000000009268002

1.

CHECK TORQUE CONVERTER CLUTCH SOLENOID VALVE

Check the resistance between the A/T unit connector terminal and ground.

Is the check result normal?

YES

>> INSPECTION END

NO

>> There is a malfunction of the torque converter clutch solenoid valve. Replace the transaxle

assembly. Refer to

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 

PG-60, "Terminal Arrangement"

.

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 

PG-20, "Wiring Dia-

gram — Ignition Power Supply —"
