WHY DO AUTOMOTIVE REPAIR FACILITIES CHARGE A DIAGNOSTIC FEE?
We completely understand. No one likes paying a fee before they even know what's wrong with their vehicle. It can feel like adding insult to injury when there is a problem with your vehicle. Diagnostic charges are one of the most questioned charges in our industry. Sometimes charging a diagnostic fee is required to determine the reason why your vehicle is not performing properly and to recommend THE CORRECT REPAIR THE FIRST TIME to solve the issue.
Ultimately, it really is less expensive to pay a qualified technician for a proper diagnosis than it is to replace components based on a hunch of what might be wrong. They may have dirty fingernails, but some senior master automobile technicians actually have as much training as medical professionalsâwhy should their time matter any less?
ACCURATE DIAGNOSIS TAKES TIME AND EXPERTISE
There's a very common misconception that the trouble codes stored in your engine computer will specifically identify a problem when have an issue or you have a warning light illuminated. There is also another misconception that a simple visual inspection or test drive will pinpoint certain issues, like a noise youâre hearing or even a fluid leak you have. Actually, both of these are more like pointing to the symptoms of a problem.
Think of it like visiting the doctor. They don't just glance at you and prescribe medication. They ask questions, run tests, and analyze the results. Say you have a temperature of 101 degrees. Your heat sensor, or thermometer, tells you that your temperature is out of the normal range. But it doesn't tell you why you have a fever. Is it the flu or a sinus infection? You need more information, more tests.
A similar example to think of is if you have a knee that has given you trouble. You wonât simply go to the doctor and ask them to replace your knee. They will have to evaluate your knee first and then possibly get imaging done so they can see exactly what the problem might be. You will be charged for not only the office visit, but also the imaging, which is similar to the diagnostics. After a doctor looks and analyzes the diagnostics, they can better determine whether surgery is the best course of action or maybe physical therapy or injections. So essentially, the result of the diagnostics gives the expert the ability to determine the best way to handle the problem at hand.
An example in auto repair, is that scan tool could point us to a code for the purge valve solenoid in your vehicle. This doesnât mean definitively that the purge valve solenoid is bad. It could be the wires connecting to the computer that are faulty and are activating the purge valve solenoid. Or it could even be the computer board connected to the purge valve solenoid. As you can see, the diagnostics tool is very helpful for auto shops, but they simply do not eliminate the time or skill needed to determine the root cause of why your vehicle is setting that code.
For any given trouble code or condition your vehicle has, there could be a number of causes. So, your vehicle symptoms and codes are just the first step. Our trained technicians take this information as a starting point and begin a diagnostic process to determine the root cause of the problem. That's when our technician's training, skills, shop equipment, scan tools, diagnostic software, computer databases, pressure gauges, multimeters, oscilloscopes, compression gauges and other specialized tools or tests get put to work diagnosing the problem and fixing it.
This process involves:
Visual inspection: Checking for obvious signs of damage or wear and tear.
Test Drive: Test driving the vehicle to try and duplicate the issue youâre having at different loads and conditions or speeds. Observing how the vehicle behaves while driving can reveal important clues about the issue.
Code scanning: Reading error codes from your car's computer system.
Testing components: Using multimeters, pressure gauges, and other equipment to assess the functionality of various parts.
Analyzing data: Interpreting the results and drawing on years of experience to reach an accurate diagnosis.
This process takes time and expertise, and our diagnostic fee ensures our technicians are compensated for their valuable skills. After the technician determines the root cause, this information is then used to prepare an estimate of labor and parts detailing what is needed to fix the issue.
