The OPL DRC Reader app not only identifies OBDII Diagnostic Trouble Codes (DTCs) but also provides essential vehicle information such as the VIN (Vehicle Identification Number) and Engine Code. The app is capable of retrieving error codes from several key modules:

• **Engine Control Module (ECU)**
• **Body Control Module (BCM)**
• **Transmission Control Module (TCM)**

Additionally, the app can read mileage data from certain modules, a feature that's available in select vehicles.

**Important Note:**

To ensure optimal performance, the OPL DRC Reader requires a compatible ELM327 Bluetooth interface with a minimum version of 1.3. Be aware that the app may not function correctly with low-quality ELM327 clones. To verify the compatibility of your interface, you can use the ELM Identifier app available on Google Play: ELM Identifier.
