What is the situation of vehicle signal interruption?
2 Answers
Vehicle signal interruption means that all or part of these signals cannot be used. The interrupt number is a code assigned by the system to each interrupt source for identification and processing. The interrupt number plays a very important role in interrupt processing. In the interrupt system with vector interrupt mode, the CPU can find the address of the interrupt service routine and realize the transfer of the program. Vehicle GPS precautions: Item 1: When selecting the installation location, if the windshield is pasted with metal heat insulation layer or heating layer, it will reduce the GPS receiving signal and cause the GPS to malfunction. At this time, pay attention to changing the installation location of the device. Item 2: Avoid placing it together with emission sources, such as wireless reversing radar, anti-theft devices, and other vehicle communication equipment. You can use cable ties to fix it, or use 3M magic tape strong double-sided adhesive to paste it firmly, except for strong magnetic adsorption.
When I encounter a signal interruption in my vehicle, the first thing that comes to mind is the turn signal or brake light suddenly not working, which can be worrying for driving safety. Common causes include a burnt-out bulb—often occurring after frequent flashing leads to filament breakage, or a blown fuse cutting off the current. Checking is simple: open the fuse box near the dashboard, locate the fuse position corresponding to the signal lights (usually marked in the manual), and if it's blown, try replacing it with a new one. Poor wiring contact is also an issue, especially in older cars where connections may come loose due to bumps or moisture. A faulty relay can also cause signals to disappear, as it controls the on-off switching of the lights. Repair shops often use a multimeter to check if the current is normal, but if you can't handle it yourself, don't hesitate to seek professional inspection. For prevention, check the lighting functions after each car wash to ensure the plugs are free from corrosion.
