Parking and Back-Up Sensor System Description - Control/Function
Parking and Back-Up Sensor System Operation
The sensors send out ultrasonic waves, receive waves reflected by an obstacle, determine the distance, and use the buzzer and/or multi-information display (MID) to tell the driver that an obstacle is near.
- The front corner sensors work any time the shift position/mode is shifted out of P position/mode, until the vehicle reaches about 9 mph (15 km/h). They do not come back on until slowing down to about 5 mph (8 km/h) or less.
- The rear corner and rear center sensors are only activated in shift to R position/mode.
- The parking and back-up sensor system is in active with its switch ON.
- The sensors must be free of debris, snow, and ice to work correctly.
Sound Pattern of the Parking and Back-Up Sensor Beeper
Intermittent/continuous alarm sounding is performed by obstacle detection indication requests and alarm sounding requests from the parking sensor system, according to the distance and the display of the obstacle detection location. A magnified warning display is generated in case of a failure of the parking sensor system.
