--- | ---
DETECTION CONDITION | • TCM detects open circuit in GND return signal line from solenoid valve. Diagnostic support note: • This is a diagnostic support DTC (monitored one per key cycle). • MIL does not illuminate. • PENDING CODE is not available. • FREEZE FRAME DATA is not available. • AT warning light does not indication. • DTC is stored in TCM memory.
POSSIBLE CAUSE | • Open circuit between 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 • Check for related Service Bulletins and/or on-line repair information availability. • Is any related repair information available? | Yes | Perform repair or diagnosis according to available repair information. • If vehicle is not repaired, go to next step.
No | Go to next step.
2 | INSPECT TCM CONNECTOR FOR POOR CONNECTION • Turn ignition key to OFF. • Disconnect TCM connector. • Check for poor connection (damaged, pulled-out, terminals, corrosion, etc.). • Are terminals okay? | Yes | Go to next step.
No | Repair or replace terminals, then go to Step 9.
3 | INSPECT TCM CIRCUIT FOR SHORT TO GROUND • Verify that TCM connector is disconnected. • Check continuity between TCM harness connector terminal 2P and ground. • Is there continuity? | Yes | Go to next step.
No | Go to Step 5.
4 | INSPECT TCM INTERNAL CIRCUIT FOR OPEN • Verify that TCM connector is disconnected. • Check continuity between TCM terminal 2P and TCM body. • Is there any continuity? | Yes | Go to Step 9.
No | Replace TCM, then go to Step 9. (See TCM REMOVAL/INSTALLATION [JA5AX-EL].)
5 | INSPECT TERMINAL COMPONENT NO.1 (12-PIN) CONNECTOR FOR POOR CONNECTION • Disconnect terminal component No.1 (12-pin) connector. • Check for poor connection (damaged, pulled-out, terminals, corrosion, etc.). • Are terminals okay? | Yes | Go to next step.
No | Repair or replace 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. • Check continuity between terminal component No.1 (12-pin) connector terminal J (transaxle case side) and ground. • Is there continuity? | Yes | Repair or replace TCM harness, then go to Step 9.
No | Go to next step.
7 | INSPECT COUPLER COMPONENT (10-PIN) CONNECTOR FOR POOR CONNECTION • Disconnect coupler component (10-pin) connector. • Check for poor connection (damaged, pulled-out, terminals, corrosion, etc.). • Are terminals okay? | Yes | Go to next step.
No | Repair or replace 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. • Check 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 next step.
No | Repair or replace coupler component, then go to next step.
9 | VERIFY TROUBLESHOOTING OF DTC P0763 COMPLETED • Make sure to reconnect all disconnected connectors. • Clear DTC from memory using WDS or equivalent. • Drive vehicle in D range and make sure that gears shift smoothly from 1GR to 5GR. • Is same DTC present? | Yes | Replace TCM, then go to next step. (See TCM REMOVAL/INSTALLATION [JA5AX-EL].)
No | Go to next step.
10 | VERIFY AFTER REPAIR PROCEDURE • Perform "After Repair Procedure". (See AFTER REPAIR PROCEDURE [JA5AX-EL].) • Is there any DTC present? | Yes | Go to applicable DTC inspection.
No | Troubleshooting completed.
