Meaning of this DTC code dump? (LeafSpy)

Just got LeafSpy and looking whether there is a code indicating issues with aux battery charging. How do I interpret this?

Ok None ---> ABS
Ok None ---> AIR BAG
C1704 0008 BCM Low Pressure FL WT-26
C1705 0008 BCM Low Pressure FR WT-26 Ok None ---> BRAKE
B29C1 2308 CHARGER EVSE VC-98
Ok None ---> EPS
P31B4 0008 EV/HEV CAN Error EVC-279 Ok None ---> HVAC Ok None ---> HV BATTERY Ok None ---> IPDM E/R Ok None ---> METER
P0A8D 0008 MOTOR CONTROL 14v Power Supply EVC-132/TMS-63
P3247 0008 MOTOR CONTROL Drive Motor A Inverter TMS-91 Ok None ---> MULTI AV Ok None ---> SHIFT
U1A05 0008 TCU USB Comm AV-199

Ok this forum is way to slow to respond, download the service manual for whatever year leaf you have at this link: http://www.nissan-techinfo.com/ Make sure to have good pdf loader as the files are large( try another large pdf over say 10mb before trying to download the Nissan files) as you only get 24H access. Will try to help you later when site speeds up.

Low tire pressures

B29C1 2308 CHARGER EVSE VC-98

There was a communication problem between the EVSE and the car charger. There are 4 different reasons possible:
A. No signal - During normal charging, although the AC power is being input, the PWM communication signal from EVSE is interrupted.
B. Signal stuck low - When normal charging, AC power is not input even though the on-board charger permits charging start.
C. Unexpected operation - When normal charging is started, AC power is input even though the EVSE communication does not start.
D. Signal stuck high - After charging is complete, AC power continues to input even though the on-board charger stops charging.

Communication error - When VCM detects an error signal that is received from AV control unit via CAN communication.

14 Volt Power Module System Voltage Low - If the 12V battery voltage is too low

USB Communications error - It is detected for malfunction of the USB communication module (communication disabled) between TCU and AV control unit.

I'm not sure what you are asking, but in my opinion, most of these errors (other than the low tire pressures) could have been caused by the low 12 volt battery, but were not the cause of the battery being low. There are quite a few threads on MNL about the 12 volt battery issues, so many have resorted to trickle charging it to keep it healthy.

Thanks a lot! I had indeed a dead 12v battery (suddenly without any reason/indication).
