DTC P0985:00

Shift solenoid E signal: Short circuit

DETECTION CONDITION

• Vehicle condition: Shift solenoid E ON signal is output while TCM is normal with engine running

• Status: Detects short to ground in shift solenoid E signal system

• Period: Confirmed 1 time in 0.5 s or more

FAIL-SAFE FUNCTION

• Inhibits learning control.

• Inhibits the manual shift control.

• Inhibits direct mode.

• Inhibits AAS mode.

• Inhibits the TCC control and slip control.

• Inhibits 5GR and 6GR.

• Inhibits the neutral control.

• Sets to emergency mode.

POSSIBLE CAUSE

• TCM connector or terminal malfunction

• Coupler component connector or terminal malfunction

• Shift solenoid E connector or terminal malfunction

• Short to ground in wiring harness between shift solenoid E terminal A and TCM terminal 2V

• Shift solenoid E malfunction

• TCM malfunction

STEP

INSPECTION

ACTION

1

NOTE:

• Recording can be facilitated using the screen capture of the PC function.

• Record the freeze frame data/snap shot data.

Go to the next step.

2

• 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

• Switch the ignition off.

• Disconnect the TCM connector.

• Inspect for poor connection at TCM terminal 2V (such as damaged/pulled-out pins, corrosion).

• Is terminal normal?

Yes

Go to the next step.

No

Repair or replace the connector and/or terminal, then go to Step 9.

4

• Inspect for resistance between TCM terminal 2V (wiring harness-side) and body ground.

• Is the resistance within 11—15 ohms?

  (See SOLENOID VALVE INSPECTION [SJ6A-EL].)

Yes

Go to Step 9.

No

Go to the next step.

5

• Switch the ignition off.

• Disconnect the coupler component connector.

• Inspect for poor connection at coupler component terminal K (such as damaged/pulled-out pins, corrosion).

• Is terminal normal?

Yes

Go to the next step.

No

Repair or replace the connector and/or terminal, then go to Step 9.

6

• Inspect the resistance between coupler component (transmission case side) terminal K and body ground.

• Is the resistance within 11—15 ohms?

  (See SOLENOID VALVE INSPECTION [SJ6A-EL].)

Yes

Go to the next step.

No

Go to Step 9.

7

• Switch the ignition off.

• Disconnect the shift solenoid E connector.

• Inspect for poor connection at shift solenoid E terminal A (such as damaged/pulled-out pins, corrosion).

• Is terminal normal?

Yes

Go to the next step.

No

Repair or replace the connector and/or terminal, then go to Step 9.

8

• Inspect the shift solenoid E.

  (See SOLENOID VALVE INSPECTION [SJ6A-EL].)

• Is the shift solenoid E normal?

Yes

Repair or replace the wiring harness (coupler component connector—shift solenoid E) for short to ground, then go to the next step.

No

Replace the control valve body, then go to the next step.

(See CONTROL VALVE BODY REMOVAL [SJ6A-EL].)

(See CONTROL VALVE BODY INSTALLATION [SJ6A-EL].)

9

• Always reconnect all disconnected connectors.

• Clear the DTC using the M-MDS.

  (See ON-BOARD DIAGNOSTIC SYSTEM DTC INSPECTION [TCM (SJ6A-EL)].)

• Perform the following procedure to ensure that the DTC has been resolved:

• Start the engine.

• Warm-up the engine and transmission.

• Drive the vehicle in D position and make sure that the gears shift smoothly from 1GR to 6GR.

• Perform the DTC inspection using the M-MDS.

  (See ON-BOARD DIAGNOSTIC SYSTEM DTC INSPECTION [TCM (SJ6A-EL)].)

• Is the same DTC present?

Yes

Replace the TCM, then go to the next step.

(See TCM REMOVAL/INSTALLATION [SJ6A-EL].)

No

Go to the next step.

10

• Clear the DTC using the M-MDS.

  (See ON-BOARD DIAGNOSTIC SYSTEM DTC INSPECTION [TCM (SJ6A-EL)].)

• Perform the DTC inspection using the M-MDS.

  (See ON-BOARD DIAGNOSTIC SYSTEM DTC INSPECTION [TCM (SJ6A-EL)].)

• Are any DTCs present?

Yes

Go to the applicable DTC inspection.

(See ON-BOARD DIAGNOSTIC SYSTEM DTC TABLE [TCM (SJ6A-EL)].)

No

DTC troubleshooting completed.
