START STOP UNIT REMOVAL/INSTALLATION

WARNING:

CAUTION:

  • Never remove bolts and screws other than the bolt in Steps 7 and 8. Otherwise, it will cause internal damage and the steering lock cannot be unlocked, resulting in the inability to perform the start-stop unit removal/installation.

  • If configuration is not performed when the start stop unit is replaced with a new one, the vehicle specification information is not stored in the start stop unit and the system will not operate normally.

  • When performing configuration, it is necessary to read the vehicle specification information from the start stop unit before replacing it. Connect the M-MDS to the vehicle and perform vehicle identification before removing the start stop unit. The vehicle specification information is temporarily stored in the M-MDS.

NOTE:

  • The start stop unit prior to replacement stores the vehicle specification information.

  • A new start stop unit does not store any vehicle specification information.

  • If the vehicle specification information from the start stop unit prior to replacement cannot be read, perform the configuration using As-Built data.
