The setting is displayed as off, which could be due to two possibilities: 1. The initial value is off, or 2. The CANBUS module is indicating to DUDU that this function is disabled.
When you clicked, DUDU sent an "enable" command, but the CANBUS module did not respond. This indicates that the command for this function in your vehicle is different from the command used by the CANBUS module, or that the CANBUS module does not support this function.
Assuming the OEM offers this option, the CANBUS box will interpret 0X90:Bit0-Bit1, and the DUDU unit will send 0/1 commands to the CANBUS box.
Could you try and see if connecting or not connecting to the original equipment manufacturer (OEM) host affects this functionality?
