When the battery is disconnected from the memory of the central unit of the engine and gearbox control system, the anti-lock brake system, as well as from the memory of a number of other electrical devices, such as a radio and clock, data on the malfunctions that have occurred are erased. After connection, reprogram the relevant devices. Some standard radios have a security code. Which prevents unauthorized use of the radio if its power is turned off.
