What is the problem?
The affected vehicles have an electrical wiring and fuse layout where the converter box is protected by the same fuse used by the signal horn and the anti-theft alarm system. If the fuse is blow (e.g. in case of an electrical short in the horn), the converter box is disconnected from the power supply, which, in turn, shuts off applications such as the engine management system, lighting system, and wipers. Should this happen while driving the vehicle, the engine could stall, or the wipers/headlights could turn off unexpectedly, potentially leading to a crash.
