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
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.

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
