Oscilloscope Measurement On System Locks: Requirements

The fuse for the central locking system F57 (up to 09/07) or F73 (as of 09/07) must be renewed. The 15 A fuse is to be renewed by a 20 A fuse! Use a 20 A fuse, even if a 15 A fuse is still indicated on the circuit diagram or on the fuse board!
