Consider a 5 year old North American vehicle with all its electronics control and gadgets. What is your chance if your vehicle breakdown and for you to fix it? Unless you have the necessary training, it is safe to say that it is remote. But miraculously, if you know the automotive wiring diagram of your vehicle, your chances just got better!

Automotive wiring is your electrical guide of your vehicle which defines how it works, functions and operates. All the detailed electrical components are displayed including their wiring colors and locations. The function of each circuit is also shown so that every wire connections is described which you need for testing. Operation wise, this automotive wiring can be tested in different modes. Example, you can test it with ignition key off without a load; with key on engine off or KOEO or do it with key on engine running called KOER. These modes will not give you the same reading because the electrical wirings are in different state of load.

Automotive wiring general guide for electrical troubleshooting:

1.) Know the common fix of your electrical problem before doing anything. Why mess around with automotive wiring or electrical troubleshooting if the fix is just to change a simple stuff like a battery? If you just simply ask anybody who has fixed your electrical problem before, then you might find the fix right away and guest what? You will stop stressing yourself!

2.) Find out the dangers to yourself before getting involved with automotive wiring. Your safety and people around you is your top priority. If you damage your car, it can be replaced but if you get hurt or killed then you might regret it for the rest of your life.

3.) Once both 2 conditions above are met then jump right in! Making a mistake is a great way to learn something and this is the best experience that you can get. School is great but nothing beats experience in automotive wiring!

For most vehicles made between 2003-2012, if you experience a NO START or intermittent engine cutting out coupled with weird lights in your dash, check the diagnostic link connector (DLC) where the scanner is hooked up. Check voltage between pin 4 or pin 5 and measured against pin 6 or pin 14, if you fail to get an average of 2.5 volts, you have a wiring problem in your data communication lines. No amount of troubleshooting using a scanner will fix it because the engine modules are not communicating. The ONLY solution is to get the exact engine wiring diagram so you can pinpoint the defective module that you can isolate and fix it. Most top mechanics can fix this type of problem using a voltmeter that you can buy from your local parts store. NO scanner needed!
