Additional Service When Replacing TCM: Description

When replacing the TCM, perform the following work.

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.

LOADING AND STORING OF CALIBRATION DATA

• The TCM acquires calibration data (individual characteristic value) of each solenoid that is stored in the ROM assembly (in the control valve). This enables the TCM to perform accurate control. After the TCM is replaced, check that the calibration data is correctly loaded and stored.

CALIBRATION OF G SENSOR

• TCM stores calibration data (inherent characteristic value) of G sensor to provide accurate control. Therefore, it is required to perform calibration of G sensor after the replacement of TCM.
