How to Jumpstart a Car: Batteries in Cars Built After Year 2000
You probably keep jumper cables in your vehicle so you can solicit a jump if your battery dies or offer a jump to a fellow driver. But jumping batteries on cars built after 2000 might not be so smart. That’s because newer vehicles contain as many as a dozen computers and even more digital devices. Jump-starting with cables connected to a running vehicle can create a voltage surge large enough to fry expensive computers in either vehicle. And, since most of these components communicate on a shared data bus, surge damage to just one computer or digital device (even a radio) can disable the entire data bus, preventing the vehicle from starting and costing hundreds to diagnose and repair. Think about that: You can cause expensive damage to your own car simply by providing a jump to someone else.
