BCM removal

1. BCM safety information

When replacing the BCM, it is necessary to write the vehicle information into the new BCM.

When replacing the BCM, before removal upload the old BCM data to a scan tool, referring to the following.

When communication with a scan tool is not possible, remove as-is.
