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.
