Description

When the transmission assembly is replaced, the learning must be performed.

Special Repair Requirement

1.ACQUIRE “IP CHARACTERISTICS DATA”

Acquire the IP characteristics data. Refer to “CONSULT-III GT-R TCM CONFIGURATION MANUAL”.

>>GO TO 2.

2.PERFORM “WRITE IP CHARACTERISTICS”

Perform “Write IP Chara - Replace TM” in “Configuration”. Refer to CONSULT-III Function (GT-R certified NISSAN dealer).

>>GO TO 3.

3.PREPARE BEFORE LEARNING

With CONSULT-III

Turn the ignition switch ON.
Check the set values of “ADJUST CLUTCH A CAPACITY”, “ADJUST CLUTCH B CAPACITY”, “CLUTCH A TOUCH POINT”, and “CLUTCH B TOUCH POINT” in "Work support".

Are the set values of all items 0?

YES>>GO TO 4.

NO>>GO TO 4 after the set values become 0.

4.PERFORM “DELETE GEAR POSITION LEARNING VALUE”

With CONSULT-III

Select “DELETE GEAR POSITION LEARNING VALUE” in “Work support”.
Select “Start”.

Can the gear position learning value be erased?

YES>>GO TO 5.

NO>>Perform again, and if it cannot be erased, check the harnesses and connectors.

5.PERFORM “DELETE CLUTCH A LEARNING VALUE”

With CONSULT-III

Select “DELETE CLUTCH A LEARNING VALUE” in “Work support”.
Select “Start”.

Can the clutch A learning value be erased?

YES>>GO TO 6.

NO>>Perform again, and if it cannot be erased, check the harnesses and connectors.

6.PERFORM “DELETE CLUTCH B LEARNING VALUE”

With CONSULT-III

Select “DELETE CLUTCH B LEARNING VALUE” in “Work support”.
Select “Start”.

Can the clutch B learning value be erased?

YES>>GO TO 7.

NO>>Perform again, and if it cannot be erased, check the harnesses and connectors.

7.PERFORM “ERASE CLUTCH ENGAGEMENT PRESSURE CORRECTION VALUE”

With CONSULT-III

Select “ERASE CLTCH ENGGMNT PRSSR CRRCTN” in “Work support”.
Select “Start”.

Can the clutch engagement pressure correction value be erased?

YES>>GO TO 8.

NO>>Perform again, and if it cannot be erased, check the harnesses and connectors.

8.SET LEARNING CONDITION

With CONSULT-III

Start the engine.
Select “RANGE”, “ACCEL POSI SEN 1”, and “FLUID TEMP” in “Data Monitor”.
Set the condition as per the following.
RANGE
: P
ACCEL POSI SEN 1
: 0.0/8
FLUID TEMP
: 50 – 85 °C (122 – 185°F)

Is the learning condition fulfilled?

YES>>GO TO 9.

NO>>GO TO 9 after the learning condition is fulfilled.

9.PERFORM “CLUTCH GEAR LEARNING”

With CONSULT-III

Perform “CLUTCH GEAR LEARNING” in “Work support”.
Select “Start”.

■ CAUTION ■
The "CLUTCH GEAR LEARNING" must be completed at temperature within 50 – 90°C (122 – 194°F). The learning is not yet completed if the temperature condition is outside the specified value during learning.

Is "completed" displayed?

YES>>End of learning

NO>>GO TO 10.

10.CHECK THE LEARNING CONDITION

With CONSULT-III

Turn the ignition switch OFF, and wait for 15 seconds or more.
Start the engine.
Select “RANGE”, “ACCEL POSI SEN 1”, “FLUID TEMP”, “BATTERY VOLTAGE”, “ENGINE SPEED”, “VEHICLE SPEED”, and “LINE PRESSURE” in “Data Monitor”.

Check that the following learning condition is fulfilled.

RANGE	: P
ACCEL POSI SEN 1	: 0.0/8
FLUID TEMP	: 50 – 85 °C (122 – 185°F)
BATTERY VOLTAGE	: 11 V or more
ENGINE SPEED	: 650 – 2,000 rpm
VEHICLE SPEED	: 3.5 km/h (2 MPH) or less
LINE PRESSURE	: 0.35 MPa (3.57 kg/cm², 50.75 psi) or more

Is the learning condition fulfilled?

YES>>GO TO 11.

NO>>GO TO 9 after the learning condition is fulfilled.

11.PERFORM “ACTIVE TEST” (CLUTCH A SOLENOID)

With CONSULT-III

Select “C/L A PRESS S/V” in the “Active Test”.
Select “CLUTCH A PRESS”, and “TGT CLUTCH A PRS”.
Raise “CLUTCH A PRESS” to 1.0 MPa (10.2 kg/cm², 145 psi), and then lower it to 0 MPa (0 kg/cm², 0 psi).
Check that “CLUTCH A PRESS” and “TGT CLUTCH A PRS” follow with an equal value.
