The application came in two distinct versions:
Before attempting to use the application, you must ensure your hardware and computer environment meet strict operational baselines. A failure mid-flash due to poor hardware can permanently corrupt (brick) an electronic control unit. 1. Computer Requirements Turn off all vehicle accessories: A/C, radio, headlights,

By moving away from hardware-based exclusivity (the DRB-III) to a software-based access model, Chrysler has maintained the security of its intellectual property while empowering independent technicians. The application will compare your current calibration ID
The democratization of flash access is not without friction.
