C1A48

G Sensor

2 seconds after the power switch is turned on (IG), the vehicle speed is 1 km/h or more and a signal from the yaw rate sensor indicating that there is a G sensor malfunction is detected by the forward recognition camera for 5 seconds or more.

  • Electronically controllde brake system

  • Yaw rate and acceleration sensor (airbag sensor assembly)

  • Forward recognition camera

CAUTION / NOTICE / HINT

Note:

  • When replacing the forward recognition camera, always replace it with a new one. If a forward recognition camera which was installed to another vehicle is used, the information stored in the forward recognition camera will not match the information from the vehicle. As a result, a DTC may be stored.

  • If the forward recognition camera has been replaced with a new one, be sure to perform forward recognition camera learning.
