Precision Diagnostics to Keep You Moving

Gone are the times when finding a problem in a vehicle took days. Thanks to diagnostics for vehicles, a mechanic can get to the bottom of an issue in minutes. Vehicles are much more sophisticated today, with built-in systems to detect and report issues. 


Looking to diagnose a problem in your vehicle? Let the experts at Hi-Tech Auto Specialists conduct diagnostic testing to find the underlying issue and help you fix it. Whether the issue is with electric or mechanical components, our technicians can handle them all with care and professionalism.

What Are Diagnostics in Vehicles?


Diagnostic service in the context of automobiles refers to diagnostic tests that identify and diagnose issues in various systems in a gas-powered vehicle. On-board diagnostics (OBD) report codes, which explain the problem. Diagnostics codes typically report problems related to the engine, battery, brakes, cooling, electrical components, and safety features like airbags. 


All vehicles made after 1995 come with an OBD2 scanner port, which connects with a scanner that runs the diagnostics software to find the specific error codes according to the make and model of the vehicle. 


At Hi-Tech Auto Specialists, our technicians use the latest diagnostic tools to diagnose issues, including minor and major ones. We provide automotive diagnostics for virtually all brands. 


What Problems Can Diagnostics Uncover?


Diagnostic vehicle equipment can uncover issues before they get bigger and more expensive. Not every issue may cause the vehicle to come to a stop. However, ignoring it may lead to complex problems. 


Some issues may not be apparent, but a diagnostic scan can reveal them. It’s recommended to get a diagnostics report periodically as a preventative measure. 

Vehicle diagnostics can find problems like:


  • Engine misfires
  • Fuel and air delivery issues
  • Catalytic converter problems
  • Oxygen sensor problems
  • Mass airflow sensor problems
  • Engine coolant temperature sensor problems
  • Transmission slipping
  • Transmission shifting problems
  • Alternator problems
  • Battery problems


Modern vehicles with electric controls can provide codes for most issues in a vehicle. And at Hi-Tech Auto Specialists, we can address those issues. With our comprehensive suite of maintenance and repair services, we can help resolve any problems after a diagnostic scan. We verify the resolution by running the scan to see if the code reoccurs. 


Signs Your Vehicle Needs a Diagnostic Scan


There are telltale signs that your vehicle needs a diagnostic service. Hi-Tech Auto Specialists technicians use the latest diagnostic equipment to scan for relevant codes based on the signs. 


  • Check engine light is on—This turns on when there’s an issue with the engine or other systems working with the engine. 
  • Warning lights—Other warning lights on your dashboard indicate an issue with or more vehicle systems. For example, brake warning lights indicate a problem with the braking system.
  • Airbag light—If this light is on, there’s an issue with your vehicle’s airbag system, and the airbags may not deploy. 
  • Power loss—If the vehicle is losing power and running slower, there may be a problem with the engine, transmission, or fuel injection system. 
  • Failed startup—If the engine isn’t turning on or the vehicle isn’t even starting, the battery may be dead. Or there could be an issue with the alternator, spark plugs, coils, or fuel injectors. 
  • Poor mileage—Mileage that’s noticeably poorer than normal is also a sign of an underlying issue. 
  • Weird smells—If you notice funky smells from the engine bay, there could be an oil or fluid leak. 
  • Rough idling—If the vehicle idles roughly, there may be issues with ignition, fuel injection, or sensors. Or your vehicle may simply need a tune-up. 
  • Non-responsive brakes—If the brakes are not responding, there’s a serious issue with the vehicle's braking system.


All of the above signs should be taken seriously. They could be linked to a minor issue but also caused by a major issue in the engine, transmission, or electrical system. These issues can cause great inconvenience and even become a safety concern if left undiagnosed. 


If you’ve experienced any of the signs above, bring your vehicle into the Hi-Tech Auto Specialists diagnostics center. Our experts will use the latest OBD2 scanners to identify and troubleshoot. They’ll provide a detailed explanation of any diagnostic codes and possible solutions. 


Once we’ve identified the issue, our experts will take the best course of action to solve the issue. Codes can also be activated due to minor problems like a disconnected wire or a dirty filter. But we make sure to check everything so no issue goes unnoticed.
