Diagnostic Tools and Equipment

Diagnostic trouble codes (DTCs) are alphanumeric codes generated by a vehicle’s onboard computer when a problem is detected in one of the vehicle systems. These codes are vital for automotive diagnostics. 


Anomalies in vehicle functions and sensors are detected by the OBD system, commonly known as OBD-II. Whenever a fault happens, the computer records a specific DTC that offers insights into the issue's characteristics. Technicians use common DTC readers and scan tools to retrieve stored codes. This helps them swiftly determine which systems need additional investigation.


DTCs provide technicians with valuable assistance in multiple ways:

  • It shows which system the problem is coming from, like the engine, transmission, or anti-lock brakes
  • The code definition identifies various issues, including excessive heat, insufficient cooling, and low voltage, that a component may face
  • If there are multiple or recurring codes, it could be a sign of a more complex problem within the system, telling us what to focus on


Simply by interpreting DTCs, Sutton Tire Inc.'s technicians can streamline their diagnostic testing process to quickly uncover the root cause of issues. This approach helps customers save time and money on repairs.


The Tools for the Job

Our automotive technicians employ specialized tools to retrieve and analyze diagnostic trouble codes. Diagnostic scanners, code readers, and scan tools link to a vehicle's diagnostic port for accessing stored DTCs. With the help of advanced equipment like oscilloscopes and multimeters, technicians can monitor live sensor data and conduct electrical system tests.


Factory scan tools also provide technicians with diagnostic routines that are specified by the automotive manufacturer. They perform tests systematically to track electrical and mechanical faults. Technicians can use laptops and diagnostic software to read trouble codes and receive real-time readings from vehicle components.


Our team at Sutton Tire Inc. uses the most advanced diagnostic tools and technology to ensure thorough vehicle testing. The scanning equipment, code readers, lab scopes, and diagnostic software we have exceed the recommendations of manufacturers. Our technicians' thorough training, combined with advanced equipment, enables us to diagnose complex issues in domestic and import vehicles efficiently.


OBD-II

OBD-II is a common onboard diagnostic system found in most vehicles today. The system monitors different parts and establishes a connection between the vehicle and a diagnostic tool.


When an issue occurs, the OBD-II system stores a diagnostic trouble code. Technicians can find valuable information in this DTC, such as the fault reporting system and specific problem details. A standardized system among manufacturers enables technicians to easily retrieve and interpret these codes.


There are several important advantages to the OBD-II system:

  • It can detect malfunctions by keeping an eye on emissions, engine parameters, and transmission controls.
  • Live system monitoring is possible for technicians with access to real-time data and sensor readings.
  • Following standardized diagnostic protocols expedites the pinpointing of faults.


OBD-II allows our technicians to identify a broad range of problems efficiently. This enhances the safety, reliability, and overall driving experience of your vehicle.


Completing the Repairs

Once the OBD-II system accurately diagnoses an issue and analyzes diagnostic trouble codes and sensor data, our technicians can quickly make the needed repairs. Using diagnostics helps Sutton Tire Inc.’s technicians avoid guesswork and unnecessary parts replacement by identifying the faulty component. Our priority is addressing the root cause of issues to avoid future problems.


Our approach to repair goes beyond surface-level solutions by incorporating diagnostic findings to address and fix vehicles. For you, that means faster repairs, lower expenses, and less downtime with reliable and quick vehicle service. Efficient repairs, enhanced performance, and various safety features all rely on the vital role of diagnostics.
