OPCOM 1.70/1.95 OBD2 Diagnostic Tool for Opel

A robust PC‑based diagnostic interface designed for Opel/Vauxhall vehicles, supporting K‑Line and multiple CAN networks. Built with a genuine PIC18F458 microcontroller and FTDI USB interface for stable communications, it enables fault code reading/clearing, live data, output tests, and service procedures across many control units.

Key Highlights

• Hardware you can trust: real PIC18F458 MCU + FTDI USB (FT232 family) for reliable throughput and driver stability
• Broad vehicle coverage: designed for many Opel/Vauxhall models, including CAN‑BUS platforms such as Vectra‑C, Astra‑H, Zafira‑B
• Multi‑bus support: HSCAN, MSCAN, SWCAN; K‑Line/ISO9141, KWP‑2000, SAE J1850 (VPW/PWM) where applicable
• Deep module access: Engine, AT/TCU, ABS/ESP, SRS Airbag, Instrument Cluster, BCM, HVAC, Cooling Module, and more (vehicle‑dependent)
• PC based: USB powered, no external supply needed; intended for Windows PCs

Note: Specific functions and coverage depend on vehicle model/year/ECU and the licensed software you use.

Core Functions

• Read/clear DTCs with detailed status (Present/Not present/Intermittent)
• Live data PIDs with up to 8 parameters displayed simultaneously; logging and graphing support
• Output/actuator tests on supported controllers
• Service utilities such as service interval resets on supported models
• ECU information readout; guided access to measuring blocks where available

Protocols and Pins

• Serial link: PIN 3/7/8/12 (ISO 9141, KW81, KW82, KWP2000)
• CAN networks:
• HSCAN: 500 kbps (dual‑wire)
• MSCAN: 95 kbps (dual‑wire)
• SWCAN: 33.3 kbps (single‑wire)
• J1850 VPW/PWM support where applicable

Performance and Compatibility

• USB interface: FTDI full‑speed USB 2.0; no need for USB‑to‑serial dongles
• Recommended OS: Windows 7 (32‑bit) or Windows XP for the smoothest driver/software setup; newer Windows versions may require additional steps
• Prerequisites: .NET Framework 3.5 SP1 on XP/Win7; run installers as Administrator

Important: Use only legally obtained software and drivers. Some legacy application builds are sensitive to OS version and drivers; follow the setup guide provided with your licensed software.

What’s Included

• 1 × OPCOM USB interface
• 1 × USB cable
• 1 × Setup/media guide

Setup Tips

• Install FTDI drivers first, then application software
• On Win7, use “Run as administrator” for first launch
• If communication is slow on older ISO‑9141 ECUs, reduce concurrent PID count for stable sampling
• Always maintain stable vehicle power during coding or actuator tests

Why Choose This Hardware

• Genuine‑spec components for consistent communication
• Multi‑CAN and K‑Line coverage for a wide range of Opel/Vauxhall ECUs
• Workshop‑friendly: fast USB, compact form factor, and proven driver stack
