It covers almost all Opel cars, including newer models with CAN-BUS based diagnostics such as -C, -H, -B. The software allows you to read and clear fault codes, view live data, and perform output tests. It supports multiple control units, including Engine, Automatic Transmission, ABS, Engine Cooling Module, Instrument Cluster, Electronic Climate Control, and Body Control Unit, among others. Due to Opel's use of multiple pins in the OBD connector, the diagnostic interface functions as a multiplexer, selecting the appropriate pin for communication. PIN3, PIN7, PIN8, PIN12 support Serial Link protocols (ISO9141, KW81, KW82, KWP2000). Fault codes are displayed with all available information. Note: Do not update the device online, as this may damage the OP-COM. No activation is required; the device is ready to use upon installation.
