Nissan Murano: Basic Inspection / Additional Service When Replacing Transaxle Assembly

Description

Perform the following work after the transaxle assembly is replaced. For work procedure, refer to Work Procedure.

NOTE:

The CD provided with the new transaxle assembly contains important calibration data that must be installed with CONSULT after installation of the new transaxle assembly. Do not discard the CD.

ERASING AND WRITING TCM DATA (IP CHARACTERISTICS VALUE)

• TCM performs accurate control by retrieving data (inherent characteristic value) of each solenoid. For this reason, after replacing transaxle assembly, it is necessary to erase data stored in TCM and write new data.

ERASING OF CVT FLUID DEGRADATION LEVEL DATA

• TCM records the degradation level of the CVT fluid calculated from the vehicle driving status. Therefore, if the transaxle assembly is replaced, it is necessary to erase the CVT fluid degradation level data recorded by TCM.

NOTE:

Before starting, make sure:

PRINT CURRENT CALIBRATION DATA

1. Turn ignition switch ON.

2. Connect CONSULT.

3. Select “CALIB DATA” in “TRANSMISSION”.

4. Print page 1 of 7.

6. Open the calibration file located on the supplied CD.

7. Confirm that the serial number (calibration file number) displayed on CONSULT screen matches the serial number (calibration file number) on the transaxle assembly.

8. Select “Next” on the “WRITE IP CHARA - REPLACEMENT AT/CVT” Work Support screen.

GO TO 4.

WRITE THE DATA

NOTE:

Write data of new solenoid in TCM according to the following instructions:

1. Turn ignition switch ON, engine OFF.
