I'm having issues querying any group of 0x79B. I'm sending the sequence 0x79B 02 21 01 00 00 00 00 00 for Group 1, and getting a proper response 7BB 10 29 61 01 FF FF F6 56 but when I ask for additional lines with 30 01 00 FF FF FF FF FF or even 30 01 00 00 00 00 00 00, I always get back "NO...
This was found to be a combination of problems. NEgative contactor in the battery was welded shut. Replaced that. Still no charging. Found QC-CAN High and Low wires reversed. QC charging is now working.
Found problem with OBC's inverter stage IGBTs. Had replace these and multiple other resisotrs and capacitors that were blown. See thread link above for details.
I have a 2015 6.6 w/QC and trying to figure why it died back in Nov. 2022 when it was working great. I'm refusing to buy another and trying to figure out which components inside the OBC have failed. I'm looking for advice in troubleshooting this...

Having a charging issue with L1. EVSE says charging, 240VAC inside the PDM. Just no output power.
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 -...
- Yes our residence's electrical panel is not balanced that well. It peaks to about 108V is the highest i've seen it. No power from the charger regardless. I have also since wired up 240VAC and no difference.
I've cross-compared a can log of my charging vs. one from a successful charge and i'm...
I'm having a problem with L1 charging all of a sudden. This vaguely coincides with the time I put dielectric grease in the J1772 port for the winter and when the temperatures started to drop.
- 2015 OBC
- 2013 24kWh battery
- 0 to -14C temperature outside. Battery temp is always above zero (i...
Having issues with my vehicle's Quick charging system and i'm running out of ideas of things to check. Normal charging works great.
What I expect:
Turn off vehicle
Insert QC plug
Hit Start button
Charging
What actually happens:
- Turn off vehicle
- Insert QC Plug
- Hit Start
- Wait 5 seconds...
