What are the causes of T-BOX failure?

Haval vehicles displaying T-BOX failure alerts require a visit to the 4S store to check the fault codes in order to confirm the failure information. Below are the related causes of T-BOX failures:1. Replacing the radar probe: In most cases, the issue lies with the vehicle's radar probe, and replacing it should resolve the problem.2. The meaning of T-BOX: T-BOX is short for Telematics BOX, referring to the intelligent vehicle terminal in the telematics system. It communicates directly with the vehicle's CAN bus to obtain body status and vehicle condition information, uploads these data parameters to the TSP backend, or receives instructions from the backend and returns execution results. T-BOX can also communicate with mobile apps to enable vehicle information display and control via the app.
Recently, my car's T-Box malfunction has been giving me a headache. Initially, I thought it was a minor issue, but it ended up causing navigation failure and affecting the remote start function. I suspect the main causes are mostly software-related, such as system update failures or crashes due to version conflicts; there are also hardware defects, like poor internal antenna reception or SIM card slot contact issues leading to signal interruptions. Power-related problems like blown fuses or unstable voltage can also damage the circuit. Additionally, parking the car in damp areas can cause water ingress and short circuits, while poor heat dissipation in high-temperature environments can exacerbate the damage. If you notice any abnormalities, I recommend trying a system reboot first—it might temporarily fix minor issues. However, for a long-term solution, it's best to visit a 4S shop promptly for a professional diagnosis of hardware issues and replacement of necessary parts to avoid compromising driving safety features. After that repair, I developed a habit of regularly cleaning the module and updating the software, which has proven quite effective.
