id050211804500

VERIFY AFTER REPAIR PROCEDURE

• Perform the “After Repair Procedure”.

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

• Are any DTCs present?

Yes

Go to the applicable DTC inspection.
(See 05-02-5 DTC TABLE[AW6A-EL, AW6AX-EL].)

DTC troubleshooting completed.

STEP

INSPECTION

ACTION

DTC P0985

Shift solenoid E circuit malfunction (short to ground/open circuit)

DETECTION

CONDITION

• Open or short circuit in shift solenoid E 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 shift solenoid E terminal B and TCM terminal B14

• Open circuit between shift solenoid E terminal A and TCM terminal B22

• Short to ground in wiring harness between shift solenoid E terminal B and TCM terminal B14

• Short to ground in wiring harness between shift solenoid E terminal A and TCM terminal B22

• Shift solenoid E malfunction

• Damaged connector between line pressure control solenoid and TCM

• TCM malfunction

STEP

INSPECTION

ACTION

VERIFY FREEZE FRAME DATA HAS BEEN
RECORDED

• Has the FREEZE FRAME DATA been

recorded?

Yes

Go to the next step.

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

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.

Go to the next step.

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.

Replace the couple component, then go to Step 8.

INSPECT RESISTANCE OF SHIFT SOLENOID E
CIRCUIT

• Inspect for resistance between couple

component terminals B14 and B22 (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.

Go to the next step.

INSPECT TERMINAL SHIFT SOLENOID E FOR
POOR CONNECTION

• Disconnect the shift solenoid E connector.

• Inspect for poor connection (such as damaged/

pulled-out pins, corrosion).

• Are terminals normal?

Yes

Go to the next step.

Replace the couple component, then go to Step 8.

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 B14 and terminal B

— Terminal B22 and terminal A

• Is there continuity?

Yes

Go to the next step.

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

INSPECT TERMINAL COUPLE COMPONENT
CIRCUIT FOR SHORT TO GROUND

• Inspect for continuity between couple

component terminals (wiring harness-side).
— Terminal B14 and all terminals except B14/

B22

— Terminal B22 and all terminals except B14/

B22

• Is there continuity?

Yes

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

Replace the control valve body, then go to the next step.
(See 05-17-38 CONTROL VALVE BODY REMOVAL/
INSTALLATION[AW6A-EL, AW6AX-EL].)

VERIFY TROUBLESHOOTING OF DTC P0985
COMPLETED

• Make sure to reconnect all the disconnected

connectors.

• Clear the DTC from the memory using the M-

MDS.

• Drive the vehicle in D range and make sure

that gears shift smoothly from 1GR to 6GR.

• Is same DTC present?

Yes

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

Go to the next step.

VERIFY AFTER REPAIR PROCEDURE

• Perform the “After Repair Procedure”.

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

• Are any DTCs present?

Yes

Go to the applicable DTC inspection.
