The more the driver understands the problem with their vehicle, the better the communication will be with the mechanic or auto repair shop.
And this communication can be critical for diagnostic charges. If the mechanic is looking for something different than your complaint much time can be wasted.
So to follow is some recommendations about understanding your individual car problem and taking it to the next level by actually doing some research before any action is taken.
Automotive diagnostics is a way of looking at a system not functioning properly and finding out why.
This is achieved with a thorough understanding of how the system that is malfunctioning, operates when in perfect working order.
Example, if you're car doesn't start and you believe that it is the fuel pump causing this condition. The first step is to sit down and understand the operation of the fuel pump circuit.
You also want to understand how the pump produces the pressure and supplies fuel to the injector rail. After understanding how the pressure is created and how this affects engine operation, diagnosis becomes much easier.
Follow the auto repair plan
The flowchart can also be known as a tree chart or even a ladder diagram. But no matter what you call it, this is a step-by-step process that will most likely lead you to success in the shortest time period.
When you follow the repair diagram, you will answer questions at each step. In most cases the answer to that question will be yes or no.
The yes answer will lead you down a different path than the no answer will. This is why it is critical to perform each step correctly. Or you will wind up going down the wrong side of the chart.
When the car repair diagram proves to be ineffective most auto mechanics will conduct a thorough visual inspection of the failed system. Often road debris can cause damage that may not fall in line with your diagnostic tree charts.
In this case, voltage and ground testing may produce unusual readings that do not match what the repair manual provides.
Sometimes fixing cars is a huge challenge and other times you find the fault quickly. So let me ask you this. Do you feel lucky?
