DTC DETECTION LOGIC
| DTC | Trouble diagnosis name | DTC detection condition | Possible causes |
| P0963 | Pressure Control Solenoid "A" Control Circuit High | The following diagnosis conditions
are met, and the current
monitor reading of the TCM line
pressure solenoid valve is 200
mA or less continuously for 0.5
seconds or more. - Diagnosis condition - Solenoid valve output current: 750 mA or more - TCM power supply voltage: 10 V < TCM power supply voltage < 16 V |
- Harness or connector
(Line pressure solenoid valve
circuit is open or shorted to
power supply.) - Line pressure solenoid valve |
DTC CONFIRMATION PROCEDURE
CAUTION: Be careful of the driving speed.
1.PREPARATION BEFORE WORK
If another "DTC CONFIRMATION PROCEDURE" occurs just before, turn ignition switch OFF and wait for at least 10 seconds, then perform the next test.
>> GO TO 2.
2.CHECK DTC DETECTION
- Start the engine.
- Maintain the following conditions for 5 seconds or more.
Selector lever : N position
Engine speed : Idle speed
3. Check the first trip DTC.
Is "P0963" detected?
YES >> Go to TM, "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis Procedure
1.CHECK CIRCUIT BETWEEN TCM AND A/T UNIT
- Turn the ignition switch OFF.
- Disconnect the TCM connector and A/T unit connector.
- Check the continuity between the TCM harness connector and the A/T unit
harness connector.
Is the check result normal?
YES >> GO TO 2.
NO >> Repair or replace the malfunctioning parts.
2.CHECK LINE PRESSURE SOLENOID VALVE
Check the line pressure solenoid valve. Refer to TM, "Component Inspection (Line Pressure Solenoid Valve)".
Is the check result normal?
YES >> Check intermittent incident. Refer to GI, "Intermittent Incident".
NO >> Repair or replace the malfunctioning parts.
Component Inspection (Line Pressure Solenoid Valve)
1.CHECK LINE PRESSURE SOLENOID VALVE
Check the resistance between the A/T unit connector and ground.
Is the check result normal?
YES >> INSPECTION END
NO >> There is a malfunction of line pressure solenoid valve. Replace the transaxle assembly. Refer to TM, "Removal and Installation".
