DATA LIST / ACTIVE TEST
DATA LIST
NOTICE:
In the table below, the values listed under "Normal Condition" are reference values. Do not depend solely on these reference values when deciding whether a part is faulty or not.
HINT:
Using the Techstream to read the Data List allows the values or states of switches, sensors, actuators and other items to be read without removing any parts. This non-intrusive inspection can be very useful because intermittent conditions or signals may be discovered before parts or wiring is disturbed. Reading the Data List information early in troubleshooting is one way to save diagnostic time.
(a) Connect the Techstream to the DLC3.
(b) Turn the engine switch on (IG).
(c) Turn the Techstream on.
(d) Enter the following menus: Body Electrical / Advanced Parking Guidance/ICS/Intuitive P/A / Data List.

Performing Active Tests early in troubleshooting is one way to save diagnostic time. Data List information can be displayed while performing Active Tests.
(a) Connect the Techstream to the DLC3.
(b) Turn the engine switch on (IG).
(c) Turn the Techstream on.
(d) Enter the following menus: Body Electrical / Advanced Parking Guidance/ICS/Intuitive P/A / Active Test.

DIAGNOSIS SYSTEM
DESCRIPTION
(a) When troubleshooting a vehicle with a diagnosis system, the only difference from the usual troubleshooting procedure is connecting the Techstream to the vehicle and reading various data output from the clearance warning ECU assembly.
The clearance warning ECU assembly stores DTCs when the ECU detects a malfunction in the ECU itself or in its circuits.
To check the DTCs, connect the Techstream to the DLC3 on the vehicle. The Techstream makes it possible to clear the DTCs, activate the various actuators, and check the freeze frame data and Data List.
CHECK DLC3
(a) Check the DLC3.

PRECAUTIONS FOR INTUITIVE PARKING ASSIST SYSTEM
(a) Under the following conditions, the detection function may not function properly:
(1) A sensor is covered with foreign matter, such as mud or snow (detection function returns to normal when the sensor is cleaned).
(2) A sensor is frozen (detection function returns to normal when the temperature of the sensor rises).
(3) A hand is blocking a sensor.
HINT:
(b) The detection range may be affected by the following conditions:
(1) A sensor is covered with foreign matter, such as mud or snow.
(2) The vehicle is in an excessively hot or excessively cold area.
(c) Under the following conditions, a detection error may occur:
(1) Driving on a bumpy road, an unpaved road or in tall grass.
(2) Ultrasonic waves are received from the horn or parking sonar system of another vehicle, a motorcycle engine, or the air brakes of a large vehicle.
(3) It is raining heavily or the sensor is sprayed with water.
(4) The vehicle is tilted at a steep angle.
(5) The vehicle is equipped with a fender pole or a wireless antenna mechanism.
(6) A sensor is covered with foreign matter, such as mud or snow.
(7) The vehicle is moving forward or backward towards high curbs or objects that are perpendicular to the ground.
(8) A sensor is sprayed with high pressure water or steam.
(9) A towing hitch is mounted on the vehicle.
(d) The sensors cannot detect the following objects:
(1) Thin objects, such as wires and ropes
(2) Materials that absorb ultrasonic waves, such as cotton or snow.
(3) Objects with sharp edges
(4) Short objects
(5) Objects that are tall and protrude toward the vehicle above the detection range of the sensors.
(e) Other notices:
(1) The sensors cannot detect objects directly under the bumper. (A sensor may detect low objects and thin poles, and then lose track of them.)
(2) Be aware that the detection range of this system is limited. In certain conditions, some objects may not be detected. Always make sure to check all around the vehicle when driving or parking.
(3) The sensors may not be able to detect obstacles that are too close to the sensors.
(4) The sensors may not be able to detect obstacles if the sensors have been dropped or subjected to a strong impact.

SYSTEM DESCRIPTION
GENERAL
(a) This system uses ultrasonic sensors to detect any obstacles at the corners and the rear of the vehicle. The system then informs the driver of the distance between the sensors and an obstacle as well as their positions by indicating them on the multi-information display (on the combination meter assembly), multi-display (on the radio and display receiver assembly) and by sounding a buzzer.
FUNCTION OF COMPONENTS
|
Component | Function |
|---|---|
|
Ultrasonic Sensor | Detects the distance between the vehicle and an obstacle |
| Sounds to inform the driver according to the distance to an obstacle |
|
Multi-information Display (on Combination Meter Assembly) |
|
| Clearance Sonar Indicator (on Combination Meter Assembly) |
Illuminates to inform the driver while the intuitive parking assist system power is on (the engine switch is on (IG) and the intuitive parking assist system is on) |
| Combination Meter Assembly |
Transmits the ON/OFF signal to the clearance warning ECU assembly |
|
Steering Pad Switch Assembly | Enables, disables or cuts off the operation of the intuitive parking assist system by transmitting the switch operation signal to the combination meter assembly |
| Clearance Warning ECU Assembly |
|
| Main Body ECU (Multiplex Network Body ECU) |
Transmits the destination information to the clearance warning ECU assembly |
|
ECM | Transmits the shift position signal to the clearance warning ECU assembly |
|
Radio and Display Receiver Assembly - Multi-display |
|
| Receives the ultrasonic sensor information via CAN communication and sends it to the multi-display through the video signal cable. |
|
Headup Display (Meter Mirror Sub-assembly)*3 |
Receives the ultrasonic sensor information via CAN communication and sends it to the headup display |
OPERATION EXPLANATION
(a) The operating conditions of each ultrasonic sensor differ according to the installation position as shown in the table below.

| Rear Center |
When the system operates, the clearance warning ECU assembly transmits ultrasonic waves from the ultrasonic sensors. If these waves encounter an obstacle within one or more of the sensors ranges, the waves are reflected back to the sensors, which transmit them to the clearance warning ECU assembly.
Based on this information, the clearance warning ECU assembly sends signals to the radio and display receiver assembly, the combination meter assembly and the No. 1 clearance warning buzzer and the No. 2 clearance warning buzzer. The approximate distance between the vehicle and the obstacle is then indicated, and the buzzer sounds.

COMMUNICATION SIGNALS OF COMPONENTS
HINT:
(a) Initialization mode:
An ID is allocated to each sensor and sensor diagnosis is performed.
(1) When the initial check is operating (the engine switch is on (IG) and the intuitive parking assist system is on), the clearance warning ECU assembly provides power to the first sensors in each series (front corner ultrasonic sensor RH and rear corner ultrasonic sensor RH).
(2) After the power is supplied, the front corner ultrasonic sensor RH and rear corner ultrasonic sensor RH enter standby mode to receive an ID from the ECU. When a certain amount of time has elapsed, the ECU sends an ID allocation signal to these sensors.
(3) The front corner ultrasonic sensor RH and rear corner ultrasonic sensor RH receive the ID allocation signal from the ECU and perform self-diagnosis. When the sensor self-diagnosis is complete, the ECU sends an ID allocation confirmation signal to the sensors.
(4) After the ID allocation confirmation is performed, the ECU provides power to the second sensors in each series (front center ultrasonic sensor RH and rear center ultrasonic sensor RH) via the first sensors. In the same manner as the first sensors, the second sensors enter standby mode. When a certain amount of time has elapsed, the ECU sends an ID allocation signal to the second sensors.
(5) The above operation will be repeated until an ID is allocated to the last sensor (front corner ultrasonic sensor LH or rear corner ultrasonic sensor LH). Initialization ends when ID allocation to all ultrasonic sensors is completed.
(b) Detection mode:
After initialization mode is completed, the system switches to detection mode. In detection mode, the clearance warning ECU assembly sends information request signals and sensor activation signals to the ultrasonic sensors and receives detection result signals from the sensors.
(1) The ECU regularly sends ID signals, information request signals, and sensor activation signals to each ultrasonic sensor according to the communication schedule.
(2) When a certain amount of time has elapsed (sensor detection operation is completed), the ECU sends an ID signal to the sensor to receive a detection result signal.
(3) The ultrasonic sensor sends a detection result signal or detection information signal to the ECU.
(4) The above operation is performed repeatedly for each ultrasonic sensor.
