Are you getting other CAN parameters from Auto CAN scan ?
I think you should use the configurator version 22.214.171.124 or higher.
Another reason, maybe your vehicle doesn't support this parameter.
For sms command, use parameter ID 376 not 3376.
Please find the below link for more details.
Thanks in advance
Yes i do get other parameters, even with Manual CAN, i just realized that FM6300 doesnt have the Vehicle Distance FEC1 included in the parameter ID. https://wiki.teltonika-gps.com/view/FM6300_AVL_ID
But for some reason i cannot read it on Manual CAN, maybe this truck has an issue. But thanks.
