Calling all backyard mechanics: If a summer road trip is in your future, let Worthington Libraries' automotive resources help you get -- and keep -- your vehicle in running condition.

If a mysterious light suddenly has appeared on your dashboard, check out an auto-code reader kit and solve the mystery.

An auto-code reader is used to diagnose the cause behind "Check Engine" or "Service Engine" dashboard lights in most vehicles manufactured since 2000. Just plug the reader into the connector under your vehicle's dash. It will display the given fault information provided by the vehicle engine, along with an explanation.

If you're up for fixing the problem yourself, a Worthington Libraries card gives you free access to databases to do that -- just start at

Chilton Library provides the same information its car care manuals have provided for more than 80 years. The online version offers photographs, diagnostics and repair procedures for both domestic and foreign cars as well as light trucks. Updates are added monthly.

If there is no time, or funds, to fix your less-than-dependable car battery, don't panic. Check out a portable car jump-starter kit before heading out on the road and be able to jump-start your engine by yourself.

The portable jump-starter may be used to start batteries in vehicles using the included jumper cables, or it may serve as a USB charging port for such devices as smartphones or tablet computers.

To access Chilton Library, start at Under the Explore tab, select Databases A-Z and then click "C" for Chilton Library. To use the database outside the library, you must be a Worthington Libraries cardholder.

Use that same card to reserve both the auto-code reader and portable car jump-starter kits. You may borrow them for 14 days; renewals are not available.
