About This Service

Modern vehicles are equipped with sophisticated computer systems that monitor and control virtually every aspect of your vehicle's operation. When something isn't working correctly, these systems generate error codes that can help identify the problem.

At D&H Auto Works, we use state-of-the-art diagnostic equipment to read these codes and identify issues with your vehicle's engine, transmission, emissions, brakes, and other critical systems. Our advanced diagnostic tools allow us to pinpoint problems quickly and accurately, saving you time and money on repairs.

• Comprehensive computer scan of all vehicle systems
• Retrieval and interpretation of diagnostic trouble codes (DTCs)
• Visual inspection of related components
• Testing of sensors and actuators as needed

Diagnostic Capabilities

Our diagnostic equipment can identify issues in various vehicle systems, including:

• Engine Management System: Fuel delivery, ignition timing, emissions control
• Transmission Control System: Shift patterns, pressure control, solenoid function

The Process

Our diagnostic process begins with a conversation about the symptoms you've noticed. This helps our technicians focus their investigation on the most likely causes of your vehicle's issues.

Next, we'll connect our diagnostic equipment to your vehicle's onboard computer system to retrieve any stored error codes. Our technicians will then interpret these codes and perform additional tests as needed to confirm the diagnosis.

Once we've identified the problem, we'll provide you with a detailed explanation of the issue and a transparent estimate for the necessary repairs. Most diagnostic services can be completed in 30-60 minutes, though complex issues may require additional time.
