INFOID:0000000000924795

System Description

INFOID:0000000000924796

• Electronic Stability Program system detects driver

′

s steering operation amount and brake pedal travel from

steering angle sensor and pressure sensor. Using information from yaw rate sensor, G sensor and wheel
sensor, ESP judges driving condition (conditions of under steer and over steer) to improve vehicle driving
stability by controlling brake application to 4 wheels and engine output.

• During ESP operation, it informs driver of system operation by flashing SLIP indicator lamp.
• Electrical system diagnosis by CONSULT-III is available.
