Implementation of quick
charge under a low Li-ion
battery level.
Perform quick charge again.
Charge power is low or
charging stops.
Power consumption is large
during charge.
A/C power consumption is
large.
Refer to
Power consumption of auxil-
iaries is large.
Charge power is limited.
Charge Insulation Resis-
tance Loss Protection Con-
trol is active.
Perform inspection according to the
diagnosis procedure of DTC
P3141. Refer to
Target charge level differs
from the meter indication.
Indication decreases after
the completion of charge.
Temperature change in Li-
ion battery.
Normal operation.
NOTE:
Charge level depends on Li-ion bat-
tery temperature. For meter indica-
tion method, refer to

scription"
.
Meter indication does not
reach maximum.
LED malfunction
Charge level is low.
Chargeable electricity is lim-
ited.

Description

CHARGE INSULATION RESISTANCE LOSS PROTECTION CONTROL
When the insulation resistance of the high voltage circuit decreases while charging due to a temporary cause,
VCM limits the charging energy and waits until the insulation resistance state recovers. VCM restarts charging
after the recovery of the insulation resistance status. If the situation is not improved after several repetitions of
this control, VCM stops charging and detects DTC P3141.
NOTE:
If the insulation resistance status does not recover despite the limitation of charging energy under protection
control, DTC P0AA6 is detected.
CHARGING CONNECTOR-CONNECTING PROTECTION CONTROL
When VCM detects a vehicle speed immediately after the charging connector is connected, the electrically-
driven intelligent brake system is activated.
NOTE:
This control cannot stop the vehicle completely.
