We Wrote the Book on Auto Emissions


auto_emissions_bibleOops. Looks like your dashboard Check Engine Light is on. What that all about? Is it okay to keep driving? More importantly, what will it cost to locate and correct the underlying problem that turned the light on in the first place?

Sam Bell and I decided it was time to answer these and other questions, so we wrote The Auto Emissions Bible to demystify the inner workings of OBD II (Onboard Diagnostic Systems, Generation Two), a software monitoring system that has been resident in one form or another in all U.S. cars and light trucks since the 1996 model year. More recently, its reach has extended to hybrids, larger trucks, and many diesel powered vehicles that are now required to meet new emissions standards.

The book includes system overviews, explanations of different OBD test modes, common test procedures, a large glossary, and a comprehensive index for fast reference to individual topics.

Richly illustrated with many pictures, charts and graphs, The Auto Emissions Bible is a great reference resource for auto repair professionals, instructors, and motorists.

Responsive Websites

Responsive web layouts are all the rage, for good reason.

Unlike traditional web sites that display pages at a fixed pixel width regardless of the screen size measured in inches, responsive sites rearrange the entire page to make it work better. They move things around to keep the text visible and the images large enough to see. They'll even switch from a traditional menu with buttons to a more compact menu tree. This all happens on-the-fly. Automatically. Cool.

This approach is far better than scaling down the entire web page, cramming it into a tiny cell phone screen, forcing you to get a magnifying glass (or start panning and zooming like mad). It also eliminates installing those annoying apps that elimnate many useful site features and a lot of good content.

The Crooked River site is responsive, and so is the new site we designed for the Silver Valley Condo Association.

Check it out. Check YOU out.

The Best Tutorials in the Business

Our .pdf tutorials are a unique blend of photography, detailed illustration, and clearly written instructions that you won't find anywhere else. The illustrations and photos give an overview of parts and locations, and the captions fill in the details.

Use Video to Sell Product

When ECS Tuning® introduced GEOMET®-coated brake rotors, they needed an attention-getting video to promote the features and benefits of their new product.

Collaboration with the ECS staff videographer produced a script and storyboard that clearly demonstrates the protection and performance afforded by GEOMET coating, complete with a brutal salt-spray test comparison test of GEOMET, zinc-coated, and stock rotors.

When visual impact is important, combine a compelling video script that tells your story, and sells your product.View the video in HD or SD.

Tool Demonstrations

Quick video demonstrations sell tools.

Customers may hesitate to buy a product until they know for sure what it will do for them, and how to use it.

This brief video for Schwaben Tools uses a combination of video footage and animated illustration to explain the features and benefits of this Euro-Car electrical terminal removal tool kit.
