CarMD Vehicle Diagnostics Kit
You're 800 miles (1287 kilometers) from home and the check engine light begins to glow ominously. Now what? You might be glad you invested in a CarMD Vehicle Diagnostics Kit. Every car made since 1996 has built-in computerized diagnostic circuitry; mechanics use it to quickly identify problems in your vehicle. The CarMD lets you do the same. A check engine light can mean something as simple as a loose gas cap, or it can alert you to a serious mechanical problem. With the CarMD, you'll know what you're dealing with.
The CarMD system doesn't just present you with a trouble code. It works with a computer program to convert that information into a description of the problem, a list of parts that might need replacing, and even the likely cost of parts and repair. It also alerts you to recalls and technical bulletins from the manufacturer. Run a scan on your car before you leave, and it will give you a heads-up on looming problems. Use it on the road if trouble pops up to figure out what you need to repair.
The CarMD readout can be a boon when you're approaching a mechanic while away from home. You'll know what's needed and what a fair price for the repair should be.
