Basics of General Auto Diagnostics
Early cars, like the Ford Model T, are relatively easy to maintain and repair. In contrast, automobiles nowadays are difficult to repair. Because of its complexity, an average car owner would find it very hard to spot a problem with his car. Generally, car owners lacking auto repair know-how would just opt for the repair shop. That’s a rational option. However, it’s quite costly. And, sometimes, auto techs take advantage of those who don’t have any idea about car repair. Therefore, having some knowledge about basic auto diagnostics is really important https://comparatifs-produits.com/valise-diagnostic/.
How do you learn basic car repair diagnostics? Nowadays, we’re blessed with the Internet. The Internet is a treasure trove of information. If you want to diagnose your car for repair, you can just search the Web for textual or multi-media instructions.
Here are some basic auto repair diagnostics.
The first thing you should remember when doing car troubleshooting is to check if the car runs. If a car won’t run, then a loose battery cable is probably the cause. Ensure to check all battery power and ground connections. See to it that the battery cable ends aren’t loose. Also, check for any signs of corrosion. Most of the time, a car won’t start because of battery problems.
You should also check if the car cranks. If it cranks but not starts, then you will need these basic tools: fuel pressure gauge, compression tester, and spark tester. Fuel pressure, compression, and spark are needed for an internal combustion engine to function. To know the exact testing steps, it’s important to consult the manufacturer or a qualified car tech.
Let’s consider a different scenario. What if the car starts but then dies after a few seconds? Most of the time, a no start condition stems from an ignition component failure-camshaft sensor problems, crankshaft sensor issues, problems with ignition module, and so on. When troubleshooting a car that starts but dies after a few moments, it’s important to ensure that you have the proper equipment. Many car owners who do not have proper equipment have improperly diagnosed their cars and caused damage to their cars’ computers. Discretion is recommended when performing auto repair troubleshooting.
Let’s move on and consider another situation. What will you do if the car runs but lacks power and a check engine light? In this case, you should consider the important things that will make your engine operate: fuel pressure, compression and spark. These three factors are really essential. When diagnosing a check engine light or drive ability problem, you should always examine fuel pressure, compression and spark. Also, you should check your car’s computer for the check engine indicator light. In this way, you may determine if there’s a circuit failure.
