A method for operating a data processing unit of a driver assistance system, the unit including main and slave computers. The main computer ascertains surroundings data from a surroundings detection system by using a processing specification. The slave computer operates a communication interface of the data processing unit, using a communication instruction. The method includes initializing, a first testing, a carrying out, a second testing and a forwarding. In initializing, the main computer, in response to a signal, is initialized by performing an initialization instruction on the main computer. In the first testing, the slave computer, in response to the signal, is initialized by performing a self-test instruction on the slave computer. In the carrying out, the communication instruction is performed on the slave computer to send and/or receive data via the communication interface, when the slave computer is tested and while the main computer is initialized. In the second testing, the main computer is tested by performing a test instruction on the slave computer, when the main computer is initialized. In the forwarding, the surroundings data are forwarded via the communication interface by performing the communication instruction on the slave computer, when the main computer is tested.

An ignition device, particularly a spark plug for internal combustion engines, permits improved corrosion protection. The ignition device includes an electrical connector and a tubular, metallic housing having a screw-in thread imprinted on it. At least one of the metallic components of the ignition device is provided at least partially with a protective coating made of a zinc/nickel alloy.

Protective coating for ignition device

An ignition device, in particular, a spark plug for Otto engines, includes an electric connection ( ) and a tubular metal housing ( ) with a screw-in thread ( ) stamped on it. At least one of the metal components of the spark plug is provided with a paint coating that serves to protect the spark plug from corrosion.
