Pcm Removal/Installation: Notes

CAUTION:
  • If configuration and reprogramming is not performed when the PCM is replaced with a new one, the vehicle specification information and PCM software is not stored in the PCM and the system will not operate normally.
  • When performing configuration and reprogramming, it is necessary to read the vehicle specification information from the PCM before replacing it. Connect the M-MDS to the vehicle and perform vehicle identification before removing the PCM. The vehicle specification information is temporarily stored in the M-MDS.

  • The PCM prior to replacement stores the vehicle specification information.
  • A new PCM does not store any vehicle specification information.
  • If the vehicle specification information PCM prior to replacement cannot be read, perform the configuration using As-Built data.
