What does T-Box malfunction mean?

[DiVivienne]

T-Box malfunction refers to issues with the onboard T-Box in the vehicle's telematics system. Below are relevant introductions about the T-Box: 1. Architecture: Dual-path DC/DC + dual-path LDO + dual-core OBD module + STM32F103CBT6 as the main controller + STM32F105RBT6 dual-core processor, with peripherals including GPRS + GPS + six-axis G-Sensor and vibration sensor for the main controller to call, plus two 12V outputs, and one reserved UART. 2. Operational states: The T-Box has 7 operational states, each represented by different states of B+, ACC, communication (call, data, SMS), GPS, and CAN. 3. Functions: The onboard T-Box can deeply read the vehicle's CAN bus data and private protocols. The T-Box terminal features a dual-core OBD module and a dual-core CPU architecture, separately collecting bus data related to Dcan, Kcan, and PTcan, and private protocol reverse control. It transmits data to the cloud server via the GPRS network, providing vehicle condition reports, driving reports, fuel consumption statistics, fault alerts, violation queries, location tracking, driving behavior, security anti-theft, appointment services, remote car finding, and the ability to control the car's doors, windows, lights, locks, horn, hazard lights, mirror folding, sunroof, monitor central console warnings, and airbag status via mobile phone.
