SAFETY WARNING! Battery 12v (51 52 53 pins) power must always be active, it cannot disappear together with ignition. It is recommended that battery 12v (51 52 53 pins) be connected directly to the battery via a 15A fuse. This is required for safety reasons. The TCU keeps the parking unlocked in case of switching off the ignition while the car is moving. It is also recommended because the TCU saves adaptations when it goes to sleep. If the TCU does not go to sleep on its own before the battery power is disconnected, the adaptations will not be saved.
