The CAN Transport Protocol (TP) physical layer defines the hardware and electrical characteristics of the CAN protocol, specifying how data is transmitted over the physical medium. It includes specifications for…
Parameter Group Numbers (PGNs) are a fundamental component of the SAE J1939 protocol, which is widely used for communication and diagnostics in heavy-duty vehicles. PGN categorize and standardize messages exchanged…
A CAN controller manages communication over a CAN bus. It handles tasks such as message framing, error detection, and message arbitration to ensure reliable data exchange between ECUs. CAN Controller…
SAE J1939 communication is a in-vehicle networking protocol for ensuring seamless interaction between ECUs in heavy-duty vehicles. Understanding the different types of SAE J1939 communication is crucial for optimizing vehicle…
Vehicle Spy (VSpy) is a versatile automotive network analysis tool used for monitoring, diagnosing, and simulating in-vehicle protocols like CAN, LIN, Automotive Ethernet and more. It is used during the…
Each CAN message in CAN protocol has a unique hexadecimal Identifier called as CAN-ID or CAN Arbitration ID. A CAN-ID uniquely identifies a CAN message. There are two types of…
In this article we will discuss the Diagnostic SID (Service Identifier) range, UDS services list and different Diagnostic Protocols (UDS, SAE J1979 OBD-II) associated with them. What is a Diagnostic…
USDT and UUDT diagnostic responses in CAN define a method of transmitting diagnostic data where large amounts of diagnostic information is divided into smaller segments or frames for transmission. What…
What is Physical Addressing vs Functional Addressing in CAN? How do these two addressing schemes differ from each other? Let's Discuss. What are Addressing schemes in a CAN network? It…
Reverse engineering a vehicle is a process of interpreting the meaning of message data without the aid of the design documents or database files. It involves a deep understanding of…
