Lost Communication with Yaw Rate Sensor Module |
w/o Full-speed range following function:
- While the vehicle speed is 36 km/h (22 mph) or more and the dynamic radar cruise control system is operating, a communication error between the yaw rate sensor and the driving support ECU assembly is detected for approximately 1 second or more.
w/ Full-speed range following function:
- While the vehicle speed is 5 km/h (3 mph) or more and the dynamic radar cruise control system is operating, a communication error between the yaw rate sensor and the driving support ECU assembly is detected for approximately 1 second or more.
