With or without saved data - every replacement has two routes:
- With previously saved data - the original unit is readable: read and save its FBS data, set the donor to "Virgin", personalize it from the file.
- Without previously saved data - the original is missing or damaged: the EIS4 file is read from the Electronic Ignition Switch over OBDII and used instead.
N.B. Unit activation happens automatically after 100 ignition cycles.
Procedures are very specific depending on your active licenses. In case of questions, please contact the Abrites team for information.
