id050211804000

DTC P0980

Shift solenoid C circuit malfunction (short to power)

DETECTION

CONDITION

• Short circuit in shift solenoid C signal system (The solenoid circuit current value input to the TCM is

continuously more than 1,333 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

• Short to power in wiring harness between shift solenoid C terminal B and TCM terminal B11

• Short to power in wiring harness between shift solenoid C terminal A and TCM terminal B10

• Shift solenoid C 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 7.

INSPECT RESISTANCE OF SHIFT SOLENOID C
CIRCUIT

• Inspect for resistance between couple

component terminals B11 and B10 (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 7.

Go to the next step.

INSPECT TERMINAL SHIFT SOLENOID C FOR
POOR CONNECTION

• Disconnect the shift solenoid C 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 7.

INSPECT TERMINAL COUPLE COMPONENT
CIRCUIT FOR SHORT TO POWER

• Inspect for continuity between couple

component terminals (wiring harness-side).
— Terminal B11 and all terminals except B11/

B10

— Terminal B10 and all terminals except B11/

B10

• 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 P0980
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.
(See 05-02-5 DTC TABLE[AW6A-EL, AW6AX-EL].)

DTC troubleshooting completed.

id050211804100

Diagnostic procedure

DTC P0981

Shift solenoid D range/performance (stuck)

DETECTION

CONDITION

• Feedback current corresponding to solenoid current command value is irregular when engine is running.

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

• ATF level low

• Deteriorated ATF

• Shift solenoid D stuck

• Control valve stuck

• 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.
