Replace the TCM, then go to the next step.
 (See 05-17-25 TCM REMOVAL/INSTALLATION[AW6A-EL, 
AW6AX-EL].)

No

Go to the next step.

8

VERIFY AFTER REPAIR PROCEDURE

• Perform the “After Repair Procedure”.

 (See 05-02-4 AFTER REPAIR 
PROCEDURE[AW6A-EL, AW6AX-EL].)

• Are any DTCs present?

STEP

INSPECTION

ACTION

DTC P0962

Line pressure control solenoid circuit malfunction (short to ground/open circuit)

DETECTION 

CONDITION

• Open or short circuit in line pressure control solenoid signal system (The solenoid circuit current value input 

to the TCM is continuously less than 23 mA for 100 ms or more).

Diagnostic support note:

• This is a continuous monitor (CCM).

• The MIL illuminates if the TCM detects the above malfunction condition during the first drive cycle.

• A PENDING CODE is not available.

• FREEZE FRAME DATA is available.

• The AT warning light illuminates.

• The DTC is stored in the TCM memory.

POSSIBLE 

CAUSE

• Open circuit between line pressure control solenoid terminal B and TCM terminal B3

• Open circuit between line pressure control solenoid terminal A and TCM terminal B1

• Short to ground in wiring harness between line pressure control solenoid terminal B and TCM terminal B3

• Short to ground in wiring harness between line pressure control solenoid terminal A and TCM terminal B1

• Line pressure control solenoid malfunction

• Damaged connector between line pressure control solenoid and TCM

• TCM malfunction

Diagnostic procedure

STEP

INSPECTION

ACTION

1

VERIFY FREEZE FRAME DATA HAS BEEN 
RECORDED

• Has the FREEZE FRAME DATA been 

recorded?

Yes

Go to the next step.

No

Record the FREEZE FRAME DATA on the repair order, 
then go to the next step.

2

VERIFY RELATED REPAIR INFORMATION 
AVAILABILITY

• Verify related Service Bulletins and/or on-line 

repair information availability.

• Is any related repair information available?

Yes

Perform repair or diagnosis according to the available 
repair information.

• If the vehicle is not repaired, go to the next step.

No

Go to the next step.

3

INSPECT TERMINAL COUPLE COMPONENT 
FOR POOR CONNECTION

• Turn the ignition switch to the LOCK position.

• Remove the TCM.

 (See 05-17-25 TCM REMOVAL/
INSTALLATION[AW6A-EL, AW6AX-EL].)

• Inspect for poor connection (such as damaged/

pulled-out pins, corrosion).

• Are terminals normal?

Yes

Go to the next step.

No

Replace the couple component, then go to Step 8.

4

INSPECT RESISTANCE OF LINE PRESSURE 
CONTROL SOLENOID CIRCUIT

• Inspect for resistance between couple 

component terminals B3 and B1 (wiring 
harness-side).

• Is resistance within 5.0— 5.6 ohms?

 (See 05-17-20 SOLENOID VALVE 
INSPECTION[AW6A-EL, AW6AX-EL].)

Yes

Go to go to Step 8.

No

Go to the next step.

INSPECT TERMINAL LINE PRESSURE 
CONTROL SOLENOID FOR POOR 
CONNECTION

• Disconnect the line pressure control solenoid 

connector.

• Inspect for poor connection (such as damaged/

pulled-out pins, corrosion).

• Are terminals normal?

Yes

Go to the next step.

No

Replace the couple component, then go to Step 8.

6

INSPECT TERMINAL COUPLE COMPONENT 
CIRCUIT FOR OPEN CIRCUIT

• Inspect for continuity between couple 

component terminals and line pressure control 
solenoid terminals (wiring harness-side).
— Terminal B3 and terminal B

— Terminal B1 and terminal A

• Is there continuity?

Yes

Go to the next step.

No

Repair or replace the couple component, then go to Step 8.

7

INSPECT TERMINAL COUPLE COMPONENT 
CIRCUIT FOR SHORT TO GROUND

• Inspect for continuity between couple 

component terminals (wiring harness-side).
— Terminal B3 and all terminals except B3/B1

— Terminal B1 and all terminals except B3/B1

• Is there continuity?

Yes

Repair or replace the couple component, then go to the 
next step.
