Comprehensive Diagnostic Services

Auto diagnostics involve using advanced tools to connect to your vehicle’s onboard computer system, which monitors various sensors and components throughout your car. This system generates codes that indicate specific issues or potential problems. At Doc Auto, our technicians are trained to interpret these codes and perform further inspections to determine the root cause of any issues. Our comprehensive diagnostic services include:

• Check Engine Light Diagnostics: The check engine light can indicate a wide range of issues, from minor to severe. Our diagnostic tools quickly identify the specific problem, allowing us to address it promptly and effectively.
• Electrical System Diagnostics: Modern vehicles rely heavily on electrical systems for everything from starting the engine to powering accessories. We can diagnose and repair electrical issues to ensure all systems function correctly.
• Engine Performance Diagnostics: If your engine isn’t running as smoothly as it should, our diagnostic tools can identify problems such as misfires, poor fuel economy, or loss of power, enabling us to make the necessary adjustments and repairs.
• Transmission Diagnostics: Transmission issues can be complex and costly if not addressed early. Our diagnostics can detect problems with shifting, fluid levels, and overall transmission health.
• Brake System Diagnostics: We use advanced tools to assess your brake system’s performance, ensuring that your vehicle stops safely and efficiently.

DOC Auto ®’s technicians are equipped and trained to accurately diagnose and repair today’s complex computerized vehicles. The function of the check engine light is sometimes misunderstood. OBD II vehicles, that is, most cars model year 1996 and newer, is the second generation of On Board Diagnostics. This second protocol is geared toward controlling emissions, not drivability. When the light is on, it typically indicates that the computer has one or more diagnostic trouble codes stored in it – these codes do not tell our auto technicians what’s wrong with the car! They just tell us what system, or systems, are affected, and what tests to run to pinpoint the problem.

The Importance of Regular Diagnostics

Regular auto diagnostics are essential for identifying and addressing potential issues before they become major problems. By catching issues early, you can save money on repairs and avoid unexpected breakdowns. Diagnostics also ensure that your vehicle operates efficiently, providing better fuel economy and performance.

Because it’s impossible for us to know what tests our techs will need to run, or even if they’ll need to run any tests without looking at the vehicle, we like to perform a free preliminary inspection before digging any deeper. This way, if the problem is something simply diagnosed by an experienced tech, you’re not committing to spending a penny unnecessarily. On the other hand, if we’re going to need to perform some pinpoint testing to truly nail down the problem, your technician will be able to tell you exactly what tests those are, and how much they’ll cost. That way, you’re in a position to make an informed decision as to how you’d like to proceed.
