A few common questions and answers about online service manuals. Below are a couple of examples of recently submitted questions I have fielded from diy car mechanics about purchasing and using online auto repair manuals.
Master tech Mark, I screwed up. I have double subscribed to the online car repair manual you recommended. I was trying to find the login page and wound up purchasing twice? What do I do now? I want to add another vehicle once I get the first vehicle straightened out.
How much is it to add additional vehicles. Is it full price? I apologize for all the questions but I am just a retired auto Mechanic not computer whiz. I Like your online auto repair website and thanks for helping me. Your new friend Bill Remington.
Bill thanks for visiting the website and for
This post is about auto repair manuals. Where they came from and how they have progressed through the years.
At the end you will learn about the future of this very important automotive information and what you can get your hands on now.
Auto repair manuals are published by independent companies rather than the manufacturers themselves. However they do pay for and get most of their information from the carmakers.
These car repair manuals contain component information, diagnostic steps, repair procedures, and specifications for several makes of automobiles in one book. Information is usually condensed and is in more general form than a manufacturer specific manual.
This condensed format allows for more coverage in less space and therefore is not always as specific or helpful. A telltale sign of one of these overview manuals would be that they would contain several model years of a specific model car in one book. Example: Ford Pinto covered from 1974-1981.
Auto repair manuals on CD

The same information that is available in service manuals is also available on several different electronic formats. In the beginning, this information was offered on CD-ROMs. And next, they were offered on DVDs, which were able to hold more information per disc.
A single DVD disc can hold a quarter of a million pages of text, eliminating the need for a huge library to contain all of the printed manuals. Using electronics to find information is also easier and quicker if they contain a search feature.
It used to be that these discs were updated on a monthly basis and not only contained the most recent service bulletins, but also engineering and field service fixes supplied by that auto manufacturer.
Web based auto repair manuals

The latest wave of this electronic auto repair information is offered in a web-based format. All of the information once contained on compact discs or DVDs is now uploaded on a central server network. This allows subscribers to access the information that is required. It also eliminates the update procedure that was required on the disc format.
The subscriber simply pays a fee and has access to the latest and greatest auto repair information available. I put together a page that shows you how this system works for the do-it-yourself car mechanic. I also provide a video that shows you what it looks like after you log in to one of these web-based auto service manuals.

How automotive diagnosis reveals car problems. The first step for diagnosis often uncovers the failure. This procedure can save diy car mechanics time. A good example of this is provided in the auto repair video below.
Automotive diagnosis is commonly used to define the primary function of a car mechanic or automotive technician. The word diagnosis is exactly the opposite of educated guessing. When a professional car mechanic performs a diagnostic procedure. He was trained to follow a series of interrelated steps in order to find a solution to a specific car problem.
Automobile diagnostics is a way of looking at the various automotive systems that are not functioning properly. It is very difficult to uncover car problems with out first understanding the purpose and operation of the system that the failure is contained within.
Repair diagrams in service manuals are diagnostic aids given for many different systems and problems that could be found within that system. The most popular of these repair diagrams are system based diagnostic charts. These flowcharts are sometimes called decision trees. They guide you through a step-by-step process in a detailed manner.
As you answer the car questions given at each step you are told what your next step should be depending on the answer to that question. These system based diagnostic charts offer a list of possible causes for each car problem.
Most automotive mechanics will perform a good visual inspection of the affected systems before they break out these diagnostic repair diagrams. Often this first step will uncover damage that is causing the complaint with the vehicle. A quick example of this is a wiring harness chewed through by a mouse. In my 25-year automotive technician career I have seen this hundreds of times.
Animals and rodents seem to love the taste of wiring insulation and also find the warm engine compartment an inviting area to explore. These unwelcome guests unfortunately can do a lot of damage in a short period of time. Performing a quick visual inspection may reveal signs of an unwanted engine compartment pet.
