Diagnostics

Many drivers put off having a diagnostic test on the mechanical or electrical systems of their car until it’s too late.  It is suggested that you have an issue diagnosed as soon as it arises, don’t let months go by with that check engine light on! The minimal cost for a diagnostic test could save you hundreds or even thousands of dollars in major repairs (if you catch a major issue early on).

Car Diagnostics – What is it?

A trained technician has a number of skills and tools at their disposal to perform electrical and mechanical diagnostics. They will take the vehicle for a test drive to note any squealing, grinding or clunking or malfunction. They will also note how the car performs. Is it slow under acceleration? Does it pull to the left or right? With the advances of technology in the automotive industry, a trained technician is now also able to communicate with your vehicle using a professional automotive scanner. A scanner is an electronic tool that an experienced technician can use to communicate with your vehicle’s engine, sensors, microchips, and more. It allows the technician to measure things such as fuel and air ratios, fuel pressure and check signals. It can also be used to activate and test specific components by commanding them on or off, such as ABS modules, fuel injectors, and TPMS sensors.
