DTC P1710 [JA5A-EL]

BME050218901229

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. (See TCM REMOVAL/INSTALLATION [JA5A-EL].)
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.
(See TCM REMOVAL/INSTALLATION [JA5A-EL].)
No | Go to the next step.
10 | VERIFY AFTER REPAIR PROCEDURE • Perform the "After Repair Procedure". (See AFTER REPAIR PROCEDURE [JA5A-EL].) • Are any DTCs present? | Yes | Go to the applicable DTC inspection. (See DTC TABLE [JA5A-EL].)
No | DTC troubleshooting completed.
