What Is Vehicle Diagnostics?

Automotive diagnostics  refers to the process of scanning your vehicle's onboard computer systems for   diagnostic trouble codes (DTCs). These codes pinpoint specific problems in systems like:

  • Engine and transmission
  • Fuel injection and air intake
  • Electrical and ignition systems
  • Battery and alternator
  • Brakes, airbags, and emission controls


All vehicles manufactured after 1995 are equipped with an   OBD-II port, which allows our certified technicians at Crow's Garage to connect a scanner and retrieve codes related to your vehicle's performance and safety systems.


What Issues Can Diagnostics Detect?

A professional diagnostic scan can reveal hidden or early-stage issues that may not yet affect driving — but could turn into costly repairs if left unaddressed.


Here’s what our diagnostics may uncover:

🚨 Engine misfires or ignition problems
🚨 Oxygen sensor or mass airflow sensor faults
🚨 Catalytic converter issues
🚨 Transmission slipping or shift delay
🚨 Alternator or battery failure
🚨 Fuel injection or delivery problems
🚨 Cooling system inefficiencies
🚨 Safety system alerts (e.g., airbag faults)


At Crow's Garage, we don’t just identify the diagnostic codes  — we explain what they mean and how to fix the issue for long-term reliability.


Signs You Need a Diagnostic Service

You don’t always have to wait for a warning light. Common symptoms that signal the need for a diagnostic service  include:


🔧   Check engine light is on
🔧   Dashboard warning lights  (brakes, ABS, oil, etc.)
🔧   Airbag warning light
🔧   Rough idling or stalling
🔧   Loss of power or acceleration
🔧   Engine won’t start
🔧   Poor gas mileage
🔧   Unusual smells or sounds

These issues can stem from something as minor as a dirty air filter or as serious as a failing sensor or control module. At Crow's Garage, we investigate thoroughly so nothing gets missed.
