System Description

INFOID:0000000003766886

• Vehicle Dynamics Control system detects driver

′

s steering operation amount and brake pedal travel from

steering angle sensor and pressure sensor. Using information from yaw rate/side G sensor and wheel sen-
sor, VDC judges driving condition (conditions of under steer and over steer) to improve vehicle driving stabil-
ity by controlling brake application to 4 wheels and engine output.

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