Op-Com 1.99 is a PC-based diagnostic interface specifically for Opel/Vauxhall vehicles (circa 2000–2014) that reads/clears fault codes, displays live data, and performs ECU programming or component tests. Typically featuring a FTDI chip and PIC18F45K80 microcontroller, it supports CAN-BUS and connects via USB, usually requiring Windows 7 or XP.

Key Features and DescriptionComprehensive Diagnostics: Reads and clears fault codes (DTCs) from engine, ABS, airbag, and other modules.Live Data & Testing: Displays real-time data from sensors and supports output tests on various components.Programming/Coding: Capable of programming keys, remote controls, and resetting Immobilizer devices (e.g., ECM, BCM, IPC).Compatibility: Covers many Opel/Vauxhall models, including CAN-BUS based systems like Vectra-C, Astra-H, and Zafira-B.Hardware Design: Often uses the PIC18F45K80 chip, which allows for stable communication and firmware updates.Common Technical SpecificationsFirmware: V1.99Software Version: Commonly bundled with 2014V (or 120309a)Connection: USBSystem Requirements: Best suited for Windows XP or Windows 7 (32-bit), often requires driver signature enforcement to be disabled for Windows 10/11.
