The invention relates to a method for applying phosphate coatings to metallic surfaces by wetting with an aqueous, acidic phosphating solution and subsequent drying of the phosphating solution, usually without subsequent rinsing, in which the phosphating solution contains 26 to 60 gl of zinc ions, 0. A screw portion is formed along part of the outer circumference of the lock pin, which is fixed to a shaft of a motor. When the STA moves to one of the neighbor APs, a reassociation is carried out between the STA and the neighbor AP using the already provided security key. The electronic circuit is further configured for performing one or more security-related operations or algorithms in response to the internally confined device-specific security data. The design provides engine oil cooling during periods of idle or slow speeds as well as while the vehicle is in motion. The clock generator may be a charge-charge clock generator including a first load capacitive element and a second load capacitive element.
