DTC CONFIRMATION PROCEDURE

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

1. Start the engine.

2. Maintain the following conditions for 5 seconds or more.

3. Check the first trip DTC.
Is “P0962” detected?

YES

>> Go to 

TM-194, "Diagnosis Procedure"

.

NO

>> INSPECTION END

Diagnosis Procedure

INFOID:0000000009267970

1.

CHECK CIRCUIT BETWEEN TCM AND A/T UNIT

1. Turn ignition switch OFF.

2. Disconnect the TCM connector and A/T unit connector.

3. Check the continuity between TCM harness connector and ground.

Is the check result normal?

YES 

>> GO TO 2.

NO

>> Repair or replace the malfunctioning parts.

Pressure Control Solenoid “A” 
Control Circuit Low

The following diagnosis condi-
tions 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 cur-

rent: 750 mA or more

- GND short circuit diagnosis 

occurs in the solenoid valve 
drive circuit.

- TCM power supply voltage: 

10 V < TCM power supply 
voltage < 16 V

• Harness or connector
