I checked the codes today.
U1116 KOS CAN Timeout
P1A30 Cell Low EV-ECU (BMU)
U1161 EV-ECU message lost (BMU)
P1AC5 MCU message lost (BMU)
U111C BMU Can timeout
P1A58 CMU07 Cell low <2.3V
U1111 which I couldn't find but i believe it's a can loss message
I must have an intermittent BMU bus problem.
Hard to tell because the only active one was U1116 which I believe is the Key
The rest were stored
I suspect the low cell is what gave me the turtle though I didn't find it in the data.
According to the service manual U1116 & U1111 can be ignored??
Agreed, a cell voltage below 2.75V will shut down the car immediately, IIRC OBDZero logs data every couple of seconds, therefore easy to miss a 'blip'.
Might help to read the DTCs immediately when this happens again...
