HEV Control System
P1A86 Inappropriate and low SOC - General Information

Component Location





General Description

The Hybrid Electric Vehicle (HEV) uses hybrid power source (Engine, Electric motor), so its fuel efficiency is relatively high and exhaust emission is very small compared to the traditional vehicle which uses only engine as power source. It consists of the engine, motor, high voltage battery and control modules.In Electric Vehicle (EV) mode, the HEV is driven by only the electric motor, but engine supports the motor in case the vehicle needs more power (HEV Mode).The electric motor not only drives the vehicle but also generates electric energy during regenerative braking for charging the high voltage battery.

DTC Description

The MCU sets P1A86 when there is SOC system failure.
