Honda Pilot: Parking and Back-Up Sensor System Description - Components

Parking and Back-Up Sensor Switch

Input to the parking and back-up sensor control unit is performed by operating the parking and back-up sensor switch. The parking and back-up sensor indicator is activated by the parking and back-up sensor control unit.

Parking and Back-Up Sensors

The parking and back-up sensors emit ultrasonic waves, which are reflected by obstacles and then detected by the sensors. The detected ultrasonic waves are converted to digital signals after amplification, and are then transmitted to the parking and back-up sensor control unit. The reference measuring distance is for a circular obstacle with a diameter of 60 mm (2.36 in). The measuring distance will be smaller when the diameter of the obstacle is less than 60 mm (2.36 in).

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 lever is shifted out of P position, 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.
• The parking and back-up sensor system is in active with its switch ON.
• The system check is performed each time the parking and back-up sensor switch is turned on with the vehicle in the ON mode.
• 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.

Parking and Back-Up Sensor System Description - Overview

The parking and back-up sensor system measures distances to objects by transmitting ultrasonic waves and receiving the echo from sound waves bouncing off nearby objects. It informs drivers of nearby objects with audible warning signals as well as visual signs through the multi-information display (MID) in the gauge control module.

*: Mounting position of the parking and back-up sensor switch is different depending on the model.

PCV System Description - Overview

Some of the unburned gases in the combustion chamber will leak through the gap between the pistons and cylinders into the crankcase. The blow-by gases that include the unburned gases are returned through the positive crankcase ventilation (PCV) valve and are burned. This prevents the blow-by gases from flowing into the atmosphere.
