What is a Car Diagnostic Test?
A car diagnostic test can reveal a number of issues related with your vehicle’s engine and transmission, oil and gas tanks, exhaust system, and other systems… With diagnostic equipment, it is possible to identify the correct cause of the fault or problem and rectify it before the problem escalates.
A common misconception about car diagnostic tests is that technicians can use code-reading tools to determine the exact problem that triggered the check engine light. In reality, the code tells technicians which engine or component parameters are out of range, but it does not detail the cause of the problems. That’s where the good old human brain comes in handy, thanks to Mc Keowns Autos experience and expertise we can diagnose the underlying problem.
A car diagnostic tool is often referred to as an OBD2 scanner and allows you to diagnose and clear error codes. OBD2 ports have been standardized in the majority of cars since 1998 and are usually located below the steering column.
Avoidable Vehicle Over Costs!
You don’t have to wait for the check engine light to get a car diagnostic test. If you hear or feel something “off,” mechanics can use diagnostic testing to uncover the problem. However, many technicians recommend taking your car in for a diagnostic check at least once a year, which will uncover minor problems that can’t be seen or heard (and that won’t trigger the check engine light).
Diagnostic testing is also a useful tool when you’re checking out a used car. Both private sellers and professional car dealers should agree to a diagnostic test before you commit to buying, and if they don’t, that’s a sign you should walk away from the deal.
