  (Open or short in the axis A feed pressure solenoid valve circuit)

A DTC is set if the status 1 or 2 below is detected with the sleeve A1 engaged in the 6th gear.

1. The difference between the clutch A speed calculated from the output shaft speed sensor value and clutch A speed sensor value is 1,000 rpm or more.
2. The difference between the clutch A speed calculated from the vehicle speed signal (meter) (CAN signal) and clutch A speed sensor value is 1,000 rpm or more.

- Clutch A speed sensor
- Sleeve A1 related part
- Harness or connector
  (Open or short in the clutch A speed sensor circuit)

DTC CONFIRMATION PROCEDURE
■ CAUTION ■

- If CONSULT-III is not available, “Diagnosis Procedure (GT-R certified NISSAN dealer)” must be performed before starting “DTC CONFIRMATION PROCEDURE”.
- If CONSULT-III is not available, never perform “DTC CONFIRMATION PROCEDURE” before completing the repair, which may cause secondary malfunction.
- Be careful of the driving speed.

1.PREPARATION BEFORE OPERATION (PART 1)
If another “DTC CONFIRMATION PROCEDURE” is performed just before the next test, turn the ignition switch OFF and wait for 10 seconds or more, then perform the next test.
>>GO TO 2.
2.PREPARATION BEFORE OPERATION (PART 2)
With CONSULT-III

1. Turn the ignition switch ON.
2. Select “FLUID TEMP” in “Data Monitor”.

Without CONSULT-III

1. Turn the ignition switch ON.
2. Check “TRANS OIL TEMP” on multi-function display.

Is the oil temperature −20°C (−4°F) or more?
YES>>GO TO 3.
NO>>Warm up the transmission.
3.PREPARATION BEFORE OPERATION (PART 3)
With CONSULT-III
Select “READ CLUTCH GEAR LEARNING DATA” in “Work support”.
Is the “6-N learning experienced” YES?
YES>>GO TO 4.
NO>>Perform “CLUTCH GEAR LEARNING”.
4.CONFIRMATION BEFORE OPERATION (PART 1)
With CONSULT-III
Select “SLEEVE A1 POSI” in “Data Monitor”.
Is the numeral value of the “SLEEVE A1 POSI” in the range between −1.7 and 1.8 mm (−0.067 and 0.071 in)?
YES>>GO TO 5.
NO>>GO TO 6.
5.CONFIRMATION BEFORE OPERATION (PART 2)
With CONSULT-III

1. Shift the shift lever to N position.
2. Start the engine.
3. Select “GEAR POSITION TEST” in “Work support”.
4. Select “GEAR6”.
   ■ CAUTION ■
   Never select “GEAR2”, “GEAR4” or “GEAR N”.

Does the sleeve A1 operate?
YES>>GO TO 6.
NO>>Go to Diagnosis Procedure (GT-R certified NISSAN dealer).
6.PERFORM DTC CONFIRMATION PROCEDURE (PART 1)
With CONSULT-III

1. Shift the shift lever to the P position and run at idle for 1 minute or more.
2. Check “Self Diagnostic Result” of “TRANSMISSION”.

Without CONSULT-III

1. Shift the shift lever to the P position and run at idle for 1 minute or more.
2. Check self-diagnosis.

Is DTC P0797 or DTC P0798 detected?
YES-1 (DTC P0797 is detected).>>Go to Diagnosis Procedure (GT-R certified NISSAN dealer).
YES-2 (DTC P0798 is detected).>>Go to Diagnosis Procedure (GT-R certified NISSAN dealer).
NO>>GO TO 7.
7.PERFORM DTC CONFIRMATION PROCEDURE (PART 2)
