DTC P1710

GND return circuit malfunction

DETECTION CONDITION

• If the TCM detects open circuit in GND return signal line from the solenoid valve, the TCM determines that there is a malfunction.
Diagnostic support note:
• This is a diagnostic support DTC (monitored one per key cycle).
• The MIL does not illuminate.
• PENDING CODE is not available.
• FREEZE FRAME DATA is not available.
• The HOLD indicator light does not flash.
• The DTC is stored in the TCM memory.

POSSIBLE CAUSE

• Open circuit in wiring harness between the duty type solenoid valves terminal and TCM terminal 2P
• Damaged connector between solenoid valve and TCM
• TCM malfunction

Diagnostic procedure

STEP

INSPECTION

ACTION

1
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.
No
Go to the next step.
2
INSPECT TCM CONNECTOR FOR POOR CONNECTION
• Turn the ignition switch to the LOCK position.
• Disconnect the TCM connector.
• Inspect for poor connection (such as damaged/pulled-out pins, corrosion).
• Are the terminals normal?
Yes
Go to the next step.
No
Repair or replace the terminals, then go to Step 9.
3
INSPECT TCM CIRCUIT FOR SHORT TO GROUND
• Verify that TCM connector is disconnected.
• Inspect for continuity between TCM wiring harness connector terminal 2P and ground.
• Is there continuity?
Yes
Go to the next step.
No
Go to Step 5.
4
INSPECT TCM INTERNAL CIRCUIT FOR OPEN CIRCUIT
• Verify that TCM connector is disconnected.
• Inspect for continuity between TCM terminal 2P and TCM body.
• Is there continuity?
Yes
Go to Step 9.
No
Replace the TCM, then go to Step 9.
5
INSPECT TERMINAL COMPONENT NO.1 (12-PIN) CONNECTOR FOR POOR CONNECTION
• Disconnect the terminal component No.1 (12-pin) connector.
• Inspect for poor connection (such as damaged/pulled-out pins, corrosion).
• Are the terminals normal?
Yes
Go to the next step.
No
Repair or replace the terminals, then go to Step 9.
6
INSPECT TERMINAL COMPONENT NO.1 (12-PIN) CIRCUIT FOR SHORT TO GROUND
• Verify that terminal component No.1 (12-pin) connector is disconnected.
• Inspect for continuity between terminal component No.1 (12-pin) connector terminal J (transaxle case side) and ground.
• Is there continuity?
Yes
Repair or replace the TCM wiring harness, then go to Step 9.
No
Go to the next step.
7
INSPECT COUPLER COMPONENT (10-PIN) CONNECTOR FOR POOR CONNECTION
• Disconnect the coupler component (10-pin) connector.
• Inspect for poor connection (such as damaged/pulled-out pins, corrosion).
• Are the terminals normal?
Yes
Go to the next step.
No
Repair or replace the terminals, then go to Step 9.
8
INSPECT COUPLER COMPONENT (10-PIN) CIRCUIT FOR SHORT TO GROUND
• Verify that coupler component (10-pin) connector is disconnected.
• Inspect for continuity between coupler component (10-pin) connector terminal A (part side) and ground.
• Is there continuity?
Yes
Repair or replace terminal component, then go to the next step.
No
Repair or replace the coupler component, then go to the next step.
9
VERIFY TROUBLESHOOTING OF DTC P0763 COMPLETED
• Make sure to reconnect all disconnected connectors.
• Clear the DTC from the TCM memory using the WDS or equivalent.
• Drive the vehicle in the D range and make sure that gears shift smoothly from 1GR to 5GR.
• Is the same DTC present?
Yes
Replace the TCM, then go to the next step.
No
Go to the next step.
10
VERIFY AFTER REPAIR PROCEDURE
• Perform the "After Repair Procedure".
• Are any DTCs present?
Yes
Go to the applicable DTC inspection.
No
DTC troubleshooting completed.
