OPL DTC Reader

OPL DTC Reader is a specialized Chrome extension designed for car enthusiasts and mechanics to read OBDII Diagnostic Trouble Codes (DTC) in Opel, Vauxhall, and Chevrolet vehicles equipped with CAN BUS (HS-CAN) systems produced after 2004. It supports major models like Opel Insignia, Astra J, Vectra C, and Chevrolet Orlando, providing detailed information from Engine Control, Body Control, and Transmission Control Modules. The extension displays vital vehicle data such as VIN and engine codes, and can read mileage from supported modules.

This tool requires a compatible ELM327 Bluetooth interface (minimum version 1.3) and ensures accurate diagnosis by rejecting low-quality ELM327 clones. Users can verify their device compatibility with the ELM Identifier app. OPL DTC Reader simplifies vehicle diagnostics, making it an essential tool for Opel, Vauxhall, and Chevrolet owners who want to maintain their vehicles efficiently and accurately.
