DTC P0985 [AW6A-EL, AW6AX-EL]

id050211804500

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

•  Coupler component connector or terminal malfunction

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

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

•  Shift solenoid E connector or terminal malfunction

•  Shift solenoid E malfunction

•  Open circuit between shift solenoid E terminal B and TCM terminal B14

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

•  TCM malfunction

DTC P0985	Shift solenoid E circuit malfunction (short to ground/open circuit)

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	• Coupler component connector or terminal malfunction • Short to GND in wiring harness between shift solenoid E terminal B and TCM terminal B14 • Short to GND in wiring harness between shift solenoid E terminal A and TCM terminal B22 • Shift solenoid E connector or terminal malfunction • Shift solenoid E malfunction • Open circuit between shift solenoid E terminal B and TCM terminal B14 • Open circuit between shift solenoid E terminal A and TCM terminal B22 • 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 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 COUPLER COMPONENT CONNECTOR FOR POOR CONNECTION • Turn the ignition switch to the LOCK position. • Remove the TCM. (See TCM REMOVAL/INSTALLATION [AW6A-EL, AW6AX-EL].) • Inspect for poor connection (such as damaged/pulled-out pins, corrosion). • Is there any malfunction?	Yes	Repair or replace the terminal, then go to Step 8.
3		No	Go to the next step.
4	INSPECT SHIFT SOLENOID E CIRCUIT FOR SHORT TO GND • Turn the ignition switch to the LOCK position. • Inspect for continuity between the following circuits: ― Coupler component terminal B14 (wiring harness-side) and body GND ― Coupler component terminal B22 (wiring harness-side) and body GND • Is there continuity?	Yes	Repair or replace the wiring harness for a possible short to GND, then go to Step 8.
4		No	Go to the next step.
5	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 (such as damaged/pulled-out pins, corrosion). • Is there any malfunction?	Yes	Repair or replace the terminal, then go to Step 8.
5		No	Go to the next step.
6	INSPECT SHIFT SOLENOID E • Inspect the shift solenoid E. (See SOLENOID VALVE INSPECTION [AW6A-EL, AW6AX-EL].) • Is there any malfunction?	Yes	Replace the control valve body, then go to Step 8. (See CONTROL VALVE BODY REMOVAL/INSTALLATION [AW6A-EL, AW6AX-EL].)
6		No	Go to the next step.
7	INSPECT SHIFT SOLENOID E CIRCUIT FOR OPEN CIRCUIT • Turn the ignition switch to the LOCK position. • Inspect for continuity between the following circuits: ― Shift solenoid E terminal B (wiring harness-side) and coupler component terminal B14 (wiring harness-side) ― Shift solenoid E terminal A (wiring harness-side) and coupler component terminal B22 (wiring harness-side) • Is there continuity?	Yes	Go to the next step.
7		No	Repair or replace the wiring harness for a possible open circuit, then go to the next step.
8	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 TCM REMOVAL/INSTALLATION [AW6A-EL, AW6AX-EL].)
8		No	Go to the next step.
9	VERIFY AFTER REPAIR PROCEDURE • Perform the “After Repair Procedure”. (See AFTER REPAIR PROCEDURE [AW6A-EL, AW6AX-EL].) • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [AW6A-EL, AW6AX-EL].)
9		No	DTC troubleshooting completed.
