Abstract
The invention relates to a method for identifying infiltration of a viscous medium (18) into an electronic assembly (10) for a vehicle, the electronic assembly (10) comprising at least one housing (40), a printed circuit board (15) and a connection region (45), the housing (40) providing an almost tight enclosure for the electronic assembly (10) and a redundancy being provided in respect of a processing and/or forwarding of electrical signals by means of the printed circuit board (15) in the electronic assembly (10), the redundancy providing at least a first transmission path (1) and a second transmission path (2) operatively parallel thereto, each transmission path (1; 2) consisting of at least one first electrical conductor (11; 21) and a second electrical conductor (12; 22), the electrical conductors (11, 12; 21, 22) each being electrically insulated from one another, and the first transmission path (1) and the second transmission path (2) forwarding the same electrical signal (U), the second transmission path (2) providing a region (30), the first electrical conductor (21) and the associated second electrical conductor (22) having no insulation in this region (30), so that an e…
