Additional Service When Replacing TCM: Description

Always perform the following items when the TCM is replaced. For work procedure, refer to Work Procedure .

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.

SAVING AND WRITING OF TCM DATA 

• TCM performs accurate control by retrieving data (inherent characteristic value) of each solenoid. For this reason, it is necessary to save data of current TCM in CONSULT before replacing the TCM. After this, the saved data must be written in new TCM.
