These devices, often called “scanners,” provide a window into the heart of your vehicle’s computer system. They allow you to diagnose problems, monitor performance, and even customize your car’s capabilities. But what exactly are OBD2 and CAN, and how do these tools work their magic?
OBD2: The Universal Language of Cars
A History of Standards
Before diving into the specifics of OBD2, it’s essential to understand its history. Prior to 1996, each car manufacturer used its own unique diagnostic system, creating a fragmented landscape for mechanics and car owners alike. This made troubleshooting and repairs cumbersome and expensive.
Enter OBD2 (On-Board Diagnostics 2), a standardized diagnostic protocol mandated by the U.S. Environmental Protection Agency (EPA). This unified system, established in 1996, made it possible for a single device, like a Cen-Tech OBD2 code reader, to communicate with a wide range of vehicles. It revolutionized the automotive repair industry and empowered car owners with greater control over their vehicles.
The OBD2 Connection: How it Works
Every car with OBD2 compliance has a standardized 16-pin connector, usually found under the dashboard. This connector acts as a doorway to the vehicle’s computer, called the Electronic Control Unit (ECU). The ECU gathers data from various sensors throughout the car, controlling everything from engine performance to emissions systems.
An OBD2 & CAN code reader plugs into this connector, establishing a communication link with the ECU. It then queries the ECU for information, including diagnostic trouble codes (DTCs) that indicate any problems detected by the car’s sensors.

CAN: The Car’s Internal Communication Network
The Rise of Networking
While OBD2 provided a standardized way to communicate with the car’s ECU, it didn’t tell the whole story. As cars became increasingly complex, with more electronic systems and sensors, a new level of communication was needed. This is where CAN (Controller Area Network) comes in.
CAN is a robust network protocol that allows different electronic modules within the car to talk to each other. It acts as a digital “nervous system,” enabling seamless information exchange between the ECU, the Anti-lock Braking System (ABS), the airbag system, and other modules.
The Power of CAN Code Readers
Cen-Tech OBD2 & CAN code readers that integrate CAN technology take diagnostic capabilities to the next level. They can access and interpret data from multiple modules within the car, providing a comprehensive picture of the vehicle’s health.
This allows for deeper diagnostics, uncovering issues that might otherwise go unnoticed. For example, a CAN-enabled scanner can reveal communication errors between the ECU and other modules, providing crucial insights for troubleshooting electrical problems.
