DTC P0763:00

Shift solenoid C electrical malfunction

DETECTION CONDITION

•  The PCM detects that output voltage to the shift solenoid C is stuck at 0 V or B+ when the solenoid valve operates according to PCM calculation.

Diagnostic support note:

•  This is a continuous monitor (CCM).

•  The MIL illuminates if the PCM detects the above malfunction conditions during the first drive cycle.

•  The HOLD indicator light flashes.

•  A PENDING CODE is available.

•  FREEZE FRAME DATA is available.

•  The DTC is stored in the PCM memory.

POSSIBLE CAUSE

•  Shift solenoid C malfunction

•  Connector or terminal malfunction

•  Open circuit in wiring harness between shift solenoid C terminal B and PCM terminal 1L

•  Short to power supply in wiring harness between shift solenoid C terminal B and PCM terminal 1L

•  Short to GND in wiring harness between shift solenoid C terminal B and PCM terminal 1L

•  Open circuit in wiring harness between shift solenoid C terminal A and body GND

•  PCM malfunction

DTC P0763:00	Shift solenoid C electrical malfunction
DETECTION CONDITION	• The PCM detects that output voltage to the shift solenoid C is stuck at 0 V or B+ when the solenoid valve operates according to PCM calculation. Diagnostic support note: • This is a continuous monitor (CCM). • The MIL illuminates if the PCM detects the above malfunction conditions during the first drive cycle. • The HOLD indicator light flashes. • A PENDING CODE is available. • FREEZE FRAME DATA is available. • The DTC is stored in the PCM memory.
POSSIBLE CAUSE	• Shift solenoid C malfunction • Connector or terminal malfunction • Open circuit in wiring harness between shift solenoid C terminal B and PCM terminal 1L • Short to power supply in wiring harness between shift solenoid C terminal B and PCM terminal 1L • Short to GND in wiring harness between shift solenoid C terminal B and PCM terminal 1L • Open circuit in wiring harness between shift solenoid C terminal A and body GND • PCM malfunction

Diagnostic procedure

STEP	INSPECTION		ACTION
1	VERIFY FREEZE FRAME DATA HAS BEEN RECORDED • Has the FREEZE FRAME DATA been recorded?	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 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.
2		No	Go to the next step.
3	INSPECT COUPLER COMPONENT CONNECTOR FOR POOR CONNECTION • Turn the ignition switch off. • Disconnect the coupler component 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 9.
3		No	Go to the next step.
4	INSPECT SHIFT SOLENOID C CONTROL CIRCUIT FOR SHORT TO POWER SUPPLY • Turn the ignition switch to the ON position (Engine off). • Measure the voltage between the coupler component terminal G (wiring harness-side) and body GND. • Is the voltage B+?	Yes	Repair or replace the wiring harness for a possible short to power supply, then go to Step 9.
4		No	Go to the next step.
5	INSPECT SHIFT SOLENOID C CONTROL CIRCUIT FOR SHORT TO GND • Turn the ignition switch off. • Inspect for continuity betweenthe coupler component terminal G (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 9.
5		No	Go to the next step.
6	INSPECT SHIFT SOLENOID C • Inspect the shift solenoid C. (See SOLENOID VALVE INSPECTION.) • Is there any malfunction?	Yes	Replace the shift solenoid C, then go to Step 9. (See SOLENOID VALVE REMOVAL/INSTALLATION.)
6		No	Go to the next step.
7	INSPECT PCM CONNECTOR FOR POOR CONNECTION • Turn the ignition switch off. • Disconnect the PCM 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 9.
7		No	Go to the next step.
8	INSPECT SHIFT SOLENOID C CONTROL CIRCUIT FOR OPEN CIRCUIT • Turn the ignition switch off. • Inspect for continuity betweenthe coupler component terminal G (wiring harness-side) and PCM terminal 1L (wiring harness-side). • Is there continuity?	Yes	Repair or replace the wiring harness for a possible open circuit, then go to the next step.
8		No	Go to the next step.
9	VERIFY TROUBLESHOOTING OF DTC P0763:00 COMPLETED • Make sure to reconnect all the disconnected connectors. • Clear the DTC from the memory using the M-MDS. • Perform the following procedure to ensure that the DTC has been resolved: ― Warm up the engine. ― Shift the selector lever to D range . ― Make sure that the gears shift smoothly from 1GR to 4GR. ― Make sure that TCC operates smoothly. • Is the same DTC present?	Yes	Replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION [ZJ, ZY].)
9		No	Go to the next step.
10	VERIFY AFTER REPAIR PROCEDURE • Perform the “After Repair Procedure”. (See AFTER REPAIR PROCEDURE.) • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE.)
10		No	DTC troubleshooting completed.
