I have been having issues since 5/2/22, warning: “12 v battery fault, service soon”(several times)
and anon-display info: “System off to save battery” ( twice)
What follows is running commentary on today’s issue/ comments…..
5-6-22, noontime, car has not been plugged in since midnight 5/1, HVB SOC is 59%
Entering car, display shows “System off to save battery”
car on , collecting OBD info, 12v SOC 37%, charging at 14.6v
12:06 pm, car off, 12v SOC 50%, 12.5v
12:08 pm, car on, 12v SOC 50%, 14.5v
** Is if possible 12v battery cannot hold a charge & is bad?! Or more likely…
** It appears DCDC converter is not being commanded on, to charge the 12v battery
12:13pm, will pull codes once 12v SOC reaches 75%
12:16pm, LvBA showing 36 amps…… is this amps being drawn from or going to the 12v battery….
looking at OBD data, it is amps being put back into the 12v battery!
@ 76% SOC, amps are 26, going down as 12v SOC goes up
12:21pm, car off, 12v SOC 78%, LvBA now settling at -7 amps!
There appears to be a 7 amp draw on the 12v battery when the car is off !?
12:26pm, car off, 12v SOC 76%, 12.7v, LvBA= -7 amps
12:27pm, car on, 12v SOC 77% charging @14.5v, LvBA= 24 amps
12:28pm, car on, DTC‘s PULLED-
Car Scanner ELM OBD2
DTC report

I continued to monitor charging of 12v battery until 1:04pm- 12v SOC 92%, maintaining 13.3v, 0 amps going in
1:05pm, car off, 12v SOC 91%, 12.7v, LvBA showing -7 amps
7 amp draw = about 84 watts….. what is the draw of my OBDLINK dongle? Can’t be anywhere near that much
I will continue to gather information….. thanks for reading….. Bill Pitman
