Looking into CAN logs I see two fairly important values being reported. Can anyone shed some light on any of these?
1. 0x5BC - LB_Power_Output_Power_Limit_Reason = "Capacity Drop"
2. 0x1DB - LB_MainRelayOn_flag = "No-Permission"
3. I do get a DTC code U100A when plugging in the charger
. - U100A is a Fail-Safe condition that stops charging because of a missing CAN message.
4. When J1772
plugged in, I always have a large draw 300-800W on the battery even though HV battery temp is above 0degreesC. As reported by Leafspy. Maybe the LBC uses a different temperature sensor and the HV battery is actually below -20C? I think is odd.
5. Yes the 12V battery has been load tested and is good.
Also in this script here is the mimimum amount of CAN messages required to enable charging in the OBC. It's written well and most people should be able to read the code

- 0x11A every 10ms
- 0x1F2 every 10ms
- 0x1D4 every 10ms
- 0x1DB every 10ms
- 0x1DC every 10ms
- 0x55B - every 100ms
- 0x5BC - every 100ms
- 0x50B - every 100ms
- 0x59E - every 500ms
But it requires an Ardiuino Due, so at the moment i'm rewriting 49thDriver's arduino code over to python using python's threading library (so far has good timing results for 10ms resolution). I've got it written and tested on my setup. No charging so far. The testing i'm doing is removing each CAN messages listed above in the sequence to see if I can get the U100A DTC to dissapear and/or reappear consistently. Currently getting mixed results and no charging yet. Next steps will be to remove the OBC from the car and bench test it with this code.
