Hi, I would appreciate having a quick checklist-style guide for analysing possible malfunctions or error states.

After reviewing the commonly available Leaf DBC files, it’s clear that there are many signals to examine. Unfortunately, not all of them are present, since the Resolve controller acts as the VCU and orchestrates much of the system. I’m particularly interested in identifying reliable CAN bus signals that indicate the pre‑charge state, main contactor states, and overall vehicle state (off / on / charging). If possible, gear status (N / R / D) would also be very useful.

It would be extremely helpful to have a Resolve‑EV‑specific DBC file containing only the relevant messages and signals. This would greatly simplify troubleshooting and diagnostic work.

Being able to determine the vehicle’s on/off/charging state via CAN messages would also make it much easier to integrate additional components such as heaters, A/C compressors, and other auxiliary systems.
