DTC P0985 [SJ6A-EL]

id050208804500

DTC P0985 | Shift solenoid E circuit malfunction (short to ground)
--- | ---
DETECTION CONDITION | • Short to ground in shift solenoid E signal system (while TCM monitors solenoid output voltage, the voltage that differs from the signal output by CPU in TCM is detected) Diagnostic support note: • The MIL illuminates if the TCM detects the above malfunction condition during first drive cycle. • The AT warning light illuminates if the TCM detects the above malfunction condition during first drive cycle. • PENDING CODE is not available. • FREEZE FRAME DATA is available. • The DTC is stored in the TCM memory.
POSSIBLE CAUSE | • TCM connector or terminal malfunction • Coupler component connector or terminal malfunction • Shift solenoid E connector or terminal malfunction • Short to GND in wiring harness between shift solenoid E terminal A and TCM terminal 1V • Shift solenoid E malfunction • TCM malfunction

Diagnostic procedure

STEP | INSPECTION | ACTION
--- | --- | ---
1 | VERIFY FREEZE FRAME DATA HAS BEEN RECORDED • Has the FREEZE FRAME DATA been recorded on the repair order? | 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 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 TCM CONNECTOR FOR POOR CONNECTION • Turn the ignition switch to the LOCK position. • Disconnect the TCM connector. • Inspect for poor connection at TCM terminal 1V (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 RESISTANCE OF SHIFT SOLENOID E CIRCUIT • Inspect for resistance between TCM terminal 1V (wiring harness-side) and body GND. • Is the resistance within 5.0—5.6 ohms? (See SOLENOID VALVE INSPECTION [SJ6A-EL].) | Yes | Go to Step 9.
No | Go to the next step.
5 | INSPECT COUPLER COMPONENT CONNECTOR FOR POOR CONNECTION • Turn the ignition switch to the LOCK position. • 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 RESISTANCE OF SHIFT SOLENOID E CIRCUIT • Inspect the resistance between coupler component (transmission case side) terminal K and body GND. • Is the resistance within 5.0—5.6 ohms? (See SOLENOID VALVE INSPECTION [SJ6A-EL].) | Yes | Go to the next step.
No | Go to Step 9.
7 | INSPECT SHIFT SOLENOID E CONNECTOR FOR POOR CONNECTION • Turn the ignition switch to the LOCK position. • 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 SHIFT SOLENOID E • 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 GND, 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 | VERIFY TROUBLESHOOTING OF DTC P0985 COMPLETED • Make sure to reconnect all the disconnected connectors. • Clear the DTC using the M-MDS. • Perform the following procedure to ensure that the DTC has been resolved: 1. Start the engine. 2. Warm-up the engine and transmission. 3. Drive the vehicle in D range and make sure that the gears shift smoothly from 1GR to 6GR. • 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 | VERIFY NO DTC HAS BEEN PRESENTED • Perform the “Reading DTCs Procedure”. (See AUTOMATIC TRANSMISSION ON-BOARD DIAGNOSTIC FUNCTION [SJ6A-EL].) • Are any DTCs present? | Yes | Go to the applicable DTC inspection. (See DTC TABLE [SJ6A-EL].)
No | DTC troubleshooting completed.
