If you're driving an Opel, Vauxhall, or Chevrolet and want to diagnose any OBDII errors, the OPL DRC Reader app is your go-to solution. Designed specifically for vehicles equipped with CAN BUS (HS-CAN) and produced after 2004, this app offers an easy way to check and understand any Diagnostic Trouble Codes (DTCs) that might be affecting your vehicle's performance.
For **Opel/Vauxhall** enthusiasts, the app supports models like the Insignia, Astra J, and even the Astra H and Vectra C/Signum, although the latter two are limited to the Engine Module. Other Opel/Vauxhall models have not been tested, so compatibility may vary.
If you're behind the wheel of a **Chevrolet**, the Orlando model is fully supported. While the Cruze has not been tested, it might still work. As with other GM brand vehicles, testing has not been conducted, so proceed with caution.
The OPL DRC Reader app is versatile, capable of displaying your vehicle's VIN, Engine Code, and a comprehensive list of detected errors across multiple modules:
- **Engine Control Module (ECU)**
- **Body Control Module (BCM)**
- **Transmission Control Module (TCM)**
Additionally, the app can read mileage from certain modules, although this feature is available only in some vehicles.
**CAUTION:** To ensure the OPL DRC Reader app functions correctly, you'll need a compatible ELM327 Bluetooth interface with at least version 1.3. Be aware that low-quality ELM327 clones may not work with the app. To check if your interface is compatible, you can use the ELM Identifier application available on Google Play: ELM Identifier.
