Motor driven Power Steering
C1101 Battery Voltage High - General Information

Component Location





General Description

A "hot at all times" from engine control relay is supplied to EPS CM as fail safe relay when EPS CM is "ON". EPS CM uses this as the source in EPS motor and system.

DTC Description

EPS CM sets this code and inhibits the current control of EPS motor if it detects a high voltage operating state has occurred due to a faulty power supply circuit or charging error. EPS CM controls the current of EPS motor accurately by compensating motor control current value according to minute voltage changes and vehicle speed. When power source is below threshold, the EPS CM inhibits the current control of EPS motor using motor current control compensations which are not in range.
