ESP (CTC)
C1102 Battery Voltage Low - General Information

Component Location





General Description

The ESC system is the shorten word of Electronic Stability Program system. This system recognizes a critical driving condition by Yaw-rate sensor, Lateral acceleration sensor and Steering angle sensor. And then it stabilizes the vehicle by a individual wheel braking and engine torque control through CAN communication. The ESC ECU (HECU, Hydraulic and Electronic Control Unit) checks the battery voltage and alternator output voltage to determine, as a safety issue, whether this system can operate normally or not. The normal battery voltage range is essential for controlling this system as intended.

DTC Description

The HECU monitors the voltage of battery and if it stays below certain value, this DTC is set.
