DTC P0982 [SJ6A-EL]

id050208804200

DTC P0982

Shift solenoid D circuit malfunction (short to ground)

DETECTION CONDITION

•  Short to ground in shift solenoid D 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 D connector or terminal malfunction

•  Short to GND in wiring harness between shift solenoid D terminal A and TCM terminal 1S

•  Shift solenoid D 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.
1		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.
2		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 1S (such as damaged/pulled-out pins, corrosion). • Is terminal normal?	Yes	Go to the next step.
3		No	Repair or replace the connector and/or terminal, then go to Step 9.
4	INSPECT RESISTANCE OF SHIFT SOLENOID D CIRCUIT • Inspect for resistance between TCM terminal 1S (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.
4		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 L (such as damaged/pulled-out pins, corrosion). • Is terminal normal?	Yes	Go to the next step.
5		No	Repair or replace the connector and/or terminal, then go to Step 9.
6	INSPECT RESISTANCE OF SHIFT SOLENOID D CIRCUIT • Inspect the resistance between coupler component (transmission case side) terminal L and body GND. • Is the resistance within 5.0—5.6 ohms? (See SOLENOID VALVE INSPECTION [SJ6A-EL].)	Yes	Go to the next step.
6		No	Go to Step 9.
7	INSPECT SHIFT SOLENOID D CONNECTOR FOR POOR CONNECTION • Turn the ignition switch to the LOCK position. • Disconnect the shift solenoid D connector. • Inspect for poor connection at shift solenoid D terminal A (such as damaged/pulled-out pins, corrosion). • Is terminal normal?	Yes	Go to the next step.
7		No	Repair or replace the connector and/or terminal, then go to Step 9.
8	INSPECT SHIFT SOLENOID D • Inspect the shift solenoid D. (See SOLENOID VALVE INSPECTION [SJ6A-EL].) • Is the shift solenoid D normal?	Yes	Repair or replace the wiring harness (coupler component connector—shift solenoid D) for short to GND, then go to the next step.
8		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 P0982 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].)
9		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].)
10		No	DTC troubleshooting completed.
