Taking your truck in for a repair usually results in having your truck put on a diagnostic system. You may know that this is one of the key steps that helps a technician figure out what truck repairs need to be made. What you may not know is how the diagnostics help narrow down issues that results in your issue being fixed. Here are a few things you need to know about what a diagnostic system does and the limitations it has on how your truck is repaired.
Signal Light Checks
One of the first things the diagnostic system checks is your signal light panel. You may bring the truck in because you think it needs an engine repair due to the lights on your truck panel. The diagnostic system will check to see if there really is a problem by ruling out issues like short circuits in your lights panel or fuses that need to be replaced. Once the system determines that you don't have a computer issue or a blown fuse, then it can move on to determine what the underlying issue leading to your truck repairs may be.
Narrowing Down the Issue
The key point to remember is that the diagnostic system can't tell the technician exactly what is wrong with your truck. What it can do is tell them where to look for an issue and narrow down what may be causing that issue. For example, if the system determines that the engine light is on due to an actual problem and not a fuse, then the technician can focus in on the engine area.
The technician may be able to use further diagnostics, depending on their system, to narrow down the engine issue even further. This will let them know if there is a possible leak in the engine, crack in the engine, or something like a temperature gauge causing the engine to overheat.
Necessity of Diagnostics Tools
The first thing many people wonder is why they bother to use the diagnostics or pay for the service if it can't detect the actual issue. The truth is, most technicians use the tools because it saves time overall. If the tools are not used, the technician would have to check each fuse panel and fuse individually to determine if there are any signal light checks.
That could take a significant amount of time for a step the diagnostics tools could rule out in a few minutes. Overall, the tools save time and get the technician focused on the area that is likely the problem rather than working through checks that may not even be an issue to begin with.
These are just a few things you need to know about your truck repairs and how diagnostic tools are used to determine issues. If you aren't sure how far the diagnostics can go at your local repair shop, ask questions so you are certain what services for truck repairs you are paying for and how it will help your issue
