On July 1, 2024, Vector Informatik GmbH, completed the full acquisition of CSM GmbH, a leading manufacturer of measurement technology based in Filderstadt, Germany. This strategic move solidifies a pa...
The Diagnostics over Internet Protocol (DoIP) is a standardized communication protocol (ISO 13400) for performing vehicle diagnostics and software updates over Ethernet. It enables faster and mor...
The CAN Transport Protocol (CAN-TP) physical layer defines the hardware & electrical characteristics of the CAN protocol and specifies how data is transmitted over the physical medium. It includes...
Parameter Group Numbers (PGNs) are a fundamental component of the SAE J1939 protocol, a vehicle network protocol used for communication and diagnostics in heavy-duty vehicles. PGN categorize and stand...
A CAN controller manages communication over the CAN bus. It handles tasks such as message framing, error detection & message arbitration to ensure reliable data exchange between ECUs. CAN Controll...
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 cruci...
Vehicle Spy (VSpy) is a automotive network analysis engineering tool used for monitoring, diagnosing, and simulating in-vehicle protocols like CAN, LIN, CAN-FD, Automotive Ethernet and more. It is use...
Each CAN message in a 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 frames or CAN-IDs i.e....
In this article we will discuss the Diagnostic SID range, UDS services list, and different diagnostic protocols (UDS, SAE J1979 OBD-II) associated with them. Understanding how each Service Identifier ...
USDT and UUDT diagnostic responses in CAN protocol define a method of transmitting diagnostic data where large amounts of diagnostic information is divided into smaller segments or frames for transmis...
What is Physical Addressing Vs Functional Addressing in CAN protocol? How do these two addressing schemes differ from each other? Physical addressing targets a specific ECU by using a unique address, ...
Reverse engineering a vehicle is a process of interpreting the meaning of message data without the aid of the database files or design documents. It involves a deep understanding of ECUs, in-vehicle n...
