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

Description

When replacing TCM and transaxle assembly simultaneously, perform the following work. 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.

TCM PROGRAMMING

• Since vehicle specifications are not yet written in a new TCM, it is necessary to write them with CONSULT.

  CAUTION:

  When replacing TCM, save TCM data on CONSULT before removing TCM.

WRITING TCM DATA (IP CHARACTERISTICS VALUE)

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

NOTE:

Before starting, make sure:

PRINT CURRENT CALIBRATION DATA

With CONSULT

1. Turn ignition switch ON.

2. Connect CONSULT.
