■ CAUTION ■
- Before TCM is replaced, it is necessary to acquire the IP characteristic data based on the information read out from the malfunctioning TCM. For acquiring the IP characteristic data, refer to “CONSULT-III GT-R TCM CONFIGURATION MANUAL”.
- If no IP characteristic data can be acquired, it is necessary to replace TCM and the transmission assembly as a set.
 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”
 3.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 4. NO >>Go to 4 after the learning condition is fulfilled.
 4.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 5.
 5.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 6. NO >>Go to 6 after the learning condition is fulfilled.
 6.PERFORM “ACTIVE TEST” (CLUTCH A SOLENOID)
 With CONSULT-III - Select “C/L A PRESS S/V” in “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.
Do “CLUTCH A PRESS” and “TGT CLUTCH A PRS” follow with an equal value? YES >>GO TO 7. NO >>Check “Self Diagnostic Result” of “TRANSMISSION”.
 7.PERFORM “ACTIVE TEST” (CLUTCH B SOLENOID)
 With CONSULT-III - Select “C/L B PRESS S/V” in “Active Test”.
- Select “CLUTCH B PRESS”, and “TGT CLUTCH B PRS”.
- Raise “CLUTCH B 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 B PRESS” and “TGT CLUTCH B PRS” follow with an equal value.
Do “CLUTCH B PRESS” and “TGT CLUTCH B PRS” follow with an equal value? YES >>GO TO 4. NO >>Check “Self Diagnostic Result” of “TRANSMISSION”.
