Here is a link to a very good YouTube channel. This guy has his own shop. I’m not affiliated with him in any way.

This episode addresses sources for online electronic troubleshooting.


Check with your local library. Sometimes they subscribe to items like these sources of self-help. Perhaps if you have a library card (or get one) you can access their auto books on line from home instead of going to the library to log on.

Some of the electronic vehicle troubleshooting, isolation, and repair pages / sections can be printed out.

Unless you have “deep pockets” and can afford an annual subscription and of $300 or more it doesn’t make sense to buy an annual sub. However, Some of these programs are available for 72 hours for a small fee of $10 to $30 depending on the vehicle.
