Auto repair and Study guide w/ General Description

Study guide for the ESP system is the shorten word of Electronic Stability Program system. Study guide 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. Study guide The ESP 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.Study guide The normal battery voltage range is essential for controlling this system as intended.
