A truck code reader is a basic plug-and-play equipment that reads and displays failure codes (DTC codes). The only things it can do are read and clear codes. The main advantages of Code Reader for Diesel Trucks are that they are far less expensive. Than scan equipment and are quite simple to use. They’re adequate for basic code scanning, but they’re not as precise as scan tools and provide significantly less detail.
Basic truck code scanners are frequently incapable of determining the nature, origin, and location of a problem. This is a significant disadvantage because if you can’t correctly diagnose the source of a problem, you may replace the wrong parts and incur unnecessary costs. Additionally, code readers do not provide freeze-frame data, diagnostic-monitor updates, or truck health data. This makes it considerably more difficult to determine if repairs have permanently solved the problem or only bandaged it.
What is a Heavy-Duty Truck Scan Tool?
A scan tool is a far more sophisticated Diagnostic Software than a Code Reader for Diesel Trucks. It reads and clears basic fault codes like a Code Reader for Diesel Trucks, but it also enables you to read pending, generic, and OEM-specific fault codes. A heavy-duty truck scan tool also specifies the exact location and nature of the defect and provides thorough truck diagnostics to assist you in determining its cause. This data contains freeze-frame information, readiness-monitor status, and diagnostic information about your truck’s supporting systems.
The most powerful Diagnostic Software and scan tools connect to specialized diagnostic laptops; however, these are highly expensive. Professional mechanics typically use diagnostic laptops that cost several thousand dollars. For owner-operators and small fleet managers, mid-range scan equipment that can connect to a smartphone or tablet is a better, more cost-effective solution.
