DIY Helpful Tips
Let’s face it, diagnosing automotive electrical, drivability or emissions-related issues can be a bit challenging. But a DIYer or automotive student armed with good diagnostic skills, a scan tool and reliable diagnostic and repair information can identify and fix most of those issues.
Diagnostic skills will develop naturally with practical experience so in this article, our focus will be on building a good fundamental knowledge of on-board diagnostics (OBD), scan tool operation, diagnostic trouble codes (DTCs) and what to do with DTCs once you’ve found them.
Most of us rely on our vehicles to take us everywhere. We jump in the driver’s seat, turn the ignition key (or push the START button) and away we go. But what happens when you turn the key, or push the button, and nothing happens? You may hear the starter slowly turnover a few times then a rapid clicking from somewhere under the dash or hood.

A good battery shouldn’t lose its charge overnight or even after sitting a few days. If it does, the problem may be the battery can no longer hold a charge, the alternator isn’t working, or the battery terminals are corroded. But if the terminals are clean and tight, the battery is fairly new and the charging system warning light is not on, there’s probably an electrical component or wiring issue causing an electrical drain (or parasitic draw) on the battery. There are a couple of ways to pinpoint which circuit, component or module is causing the battery to discharge.
Your vehicle's onboard diagnostic system can generate numerous diagnostic trouble codes (DTCs) to identify repair issues that require attention. While the specific codes may vary depending on the make, model, and year of the vehicle, there are some common DTCs that tend to occur across different vehicles. ALLDATAdiy makes it easy to interpret DTCs and determine your best course of action, based on the latest manufacturer information.
Your sense of sight is one of the most effective of your five senses when it comes to identifying problems with your vehicle.

If you get a whiff of an unusual smell coming from your vehicle, don’t ignore it. Here are eight of the most common automobile smells. You can use them as a guide to sniff out problems like a pro.
For centuries, humans have been interacting with machines. Our sense of touch has enabled us to create and manipulate all sorts of devices; marvelous inventions that we’ve designed to make our lives easier, fun and more efficient. The vehicles we drive everyday are perfect examples. But what do we do when they break down?
