for this vehicle do you have the program number? because if you use the wrong program number it will not get the correct value.
we have some schematic diagrams but for security reasons, we do not share any official file on the community forum as it is public.
there is another option also if you have fmb140 there is an auto-scan option so you can find the exact program number and parameters.
if you are not able to get it, please reach out to us via VIP Helpdesk or contact your sales manager/distributor. If you don't have any contacts with our sales managers, please contact them on our official website https://teltonika-gps.com/ and click on the "Contact Us" button. When you will click, please fill out the form and submit it.
Note: as a topic, please choose "Vehicle telematics" or you can send an e-mail with the description of your situation to https://teltonika-iot-group.com/about-us/contacts/
Thank you for your understanding.
Kind regards.
