OP-COM The PC based OPEL diagnostic tool

Auto-M3 Ltd. (Freeware)

OP-COM is a Windows-based diagnostic application package for Vauxhall and Opel cars. The package works on a variety of Opel cars. It can be used even with new cars that employ CAN-bus-based diagnostics, such as the Zafira-B, Astra-H, and Vectra-C.

CAN-bus (which stands for controller area network) is a type of protocol used in the OBD-II standard of diagnostics. It is required for trucks and cars that are sold in the United States since 1996 to have an on-board diagnostics (OBD) port. On-board diagnostics is an automotive term that refers to a vehicle's capability to self-diagnose and generate reports about its own status. Modern OBD makes use of standardized digital communications port that gives real-time information about the vehicle's system. This helps car owners and technicians quickly detect and identify malfunctions as well as determine solutions.

Diagnostic codes are sent through the computer systems of the computer and read by diagnostic tools plugged into the OBD port. The interface is designed to read and eliminate fault codes, display live data, and allow output tests. Key programming and remote features are also available. The application supports the inspection of a wide range of automotive units and systems, such as the engine, transmission, radio, electronic climate control, engine cooling module, and so on. Opel makes use of many pins in the OBD connector. OP-COM addresses this through its diagnostic interface that functions like a multiplexer and intuitively chooses the suitable pin for communication.
