About Automotive Scanner
It may be easy to see a flashing check engine light, but deciphering what it means is not always as simple. That is where an automotive scanner comes in. Volkswagen introduced the first on-board diagnostics computer way back in 1969, and until the 2000s, this meant driving—or towing—your distressed vehicle to the nearest professional to find out what was wrong. Thankfully, consumer technology has caught up with auto manufacturing, and a personal automotive scanner is well within any car owner's budget. Also known as diagnostic code readers, these scanners help owners interpret dashboard diagnostics to determine if a flashing alert is triggered by a serious problem or simply a maintenance milestone. The issue can be as minor as a blown fuse on one of the electronic accessories or as serious as an O2 sensor problem that is hampering your car's performance and efficiency. You can find a number of automotive diagnostic tools on eBay. The next time your engine light goes on, instead of covering it with duct tape, you can find out what the problem is right away.
