| Description | This article describes the steps to troubleshoot issues encountered with the CVC600 device. |
| Scope | FortiAP-U. |
| Solution | The Compact Vehicle Controller (CVC), designed to monitor vehicle status, supports WLAN communication. This device enables the transmission of vehicle status information to a remote server wirelessly.
CVC600 devices are experiencing difficulty connecting to the SSID broadcasted by FortiAP-U-223EV models, although they can connect without issue to other FortiAP models.
