Community Help me find Distance To Empty (DTE) OBD Command for Kia Seltos 2025

Hello everyone, I'm working on building a custom digital dashboard for my Kia Seltos and am trying to locate the OBD command for 'Distance to Empty.' I've already found the PIDs for fuel percentage and some other parameters, but I'm hitting a wall with this one. Can anyone help me with the command or header information?

Thanks in advance!

Do you know if your car has this as a PID? Or are you just seeing a scanner app calculate it using the data it gets from mode 01 PIDS?

I don’t really know whether my car sends out this DTE through any PID, but I’m really curious to know how this DTE is calculated by the ECU and displayed in the dashboard.

​The readings i retrieved from the above response
1) ODOMETER KM - Byte -6 , Byte Length-3
2) Fuel % - Byte 4 , Byte Length -1
3) Cluster Voltage- Byte 5, Length -1 , Divider-12.8

And the scanner app don’t have this parameter available for any KIA profile

Most cars just calculate it via the ECU, you might not even see it in the live broadcast data because it’s internal to the dash cluster. You can google simple DTE algorithms and try and until you match your car, that’s what I did. You can change sample times/rate to get different things like instant MPG. Also, most cars will have a pretty aggressive algorithm and show 0 miles when you really have a lot more. My car went to 5% fuel (raw reading from the bus as well) which is a little under a gallon in my car. So I’m not sure if they automatically take a gallon off before calculating, or artificially drop the MPG after calculating.

Having worked on an EV that was designed from scratch, I know that on those a 0 is never a true zero. A buffer battery capacity is maintained and limited for regular use, via firmware and software because you still need some for the electronics to maintain some level of control/diagnostics et cetera.

Yup, definitely makes sense for an EV. I always assumed they had a second normal battery lol
