Allow the installation sequence to conclude without manual interruption. Upon automated system reboot, navigate to the system diagnostics panel to confirm that the operational firmware string reads Jcac10003-oc2-v1.0 . Troubleshooting and Fault Isolation
One of the most significant improvements is the updated CANBus protocol support. The CANBus system handles essential functions like steering wheel controls, door status displays, climate control integration, and backup camera activation. This update provides better compatibility with various CANBus boxes, including models from Raise, Simple, and other manufacturers.
The system will automatically scan the root index of your USB drive, detect the package, and prompt an confirmation message.
