If you own an Opel, Vauxhall, or Chevrolet vehicle produced after 2004 with CAN BUS (HS-CAN), the OPL DRC Reader app is your go-to solution for checking OBDII Diagnostic Trouble Codes (DTCs). This dedicated app supports a variety of models, making it easier to diagnose engine issues directly from your smartphone.
**Supported Models:**
- **Opel / Vauxhall:** The app is compatible with models like the Insignia, Astra J, and for engine module diagnostics only, the Astra H and Vectra C / Signum. Other models within this brand have not been tested yet.
- **Chevrolet:** You can use the app with the Orlando model, while the Cruze and other Chevrolet models have not been tested.
- **Other GM Brand Vehicles:** These have not been tested for compatibility with the OPL DRC Reader app.
The app provides detailed information such as the Vehicle Identification Number (VIN), Engine Code, and a comprehensive list of detected errors across various control modules:
- **Engine Control Module (ECM/ECU):** This module controls the engine's operation and is crucial for diagnosing engine-related issues.
- **Body Control Module (BCM):** Responsible for managing various vehicle systems, such as lighting and security.
- **Transmission Control Module (TCM):** Oversees the operation of the vehicle's transmission, ensuring smooth gear changes.
Additionally, the OPL DRC Reader can read the mileage from some of these modules, although this feature's availability may vary depending on the vehicle model.
**Important Note:**
To ensure the app functions correctly, you'll need a compatible ELM327 Bluetooth interface with a minimum version of 1.3. Be cautious, as the app may not work with low-quality ELM327 clones. To verify the compatibility of your interface, you can use the ELM Identifier application available on Google Play at this link.
