OPCOM-Diagnosegerät für Opel

The OPCOM PIC18F458 CAN‑BUS interface is one of the most powerful and widely used diagnostic tools for Opel and Vauxhall vehicles. Designed specifically for GM/Opel platforms, this dealer‑style diagnostic scanner gives you deep access to vehicle systems that generic OBD2 scanners cannot reach.

Built with the reliable FTDI FT232 + PIC18F458 chipset combination and supporting CAN‑BUS, ISO9141, and KWP2000 communication protocols, OPCOM allows you to perform advanced diagnostics, coding, module resets, live data monitoring, immobilizer programming, and service functions on most Opel/Vauxhall vehicles from approximately 1990–2021.

Unlike many unstable V1.99 clones, this version uses firmware V1.70, which supports proper firmware flashing and significantly better reliability.

Whether you’re diagnosing an engine problem, programming a replacement module, resetting service lights, or troubleshooting CAN communication faults, OPCOM delivers dealership‑level access directly from your laptop.
