In order to avoid incorrect programming procedures and Check Control message, it is essential to always use the most recent version when working with the ISTA/P programming system.
Battery voltage must not undershoot 13.0 V during programming. Connect battery charger prior to programming.
Only use battery chargers* recommended by BMW for low voltage vehicle electrical system.

*Refer to the applicable BMW equipment catalogue.
