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).

intermittent operation may be discovered before parts or wiring is
disturbed. 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.

Diagnosis System
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.

System Description
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.

OPERATION EXPLANATION
(a)
The operating conditions of each ultrasonic sensor differ according to
the installation position as shown in the table below.
|
Installation Position | Operating Condition |
|
Front Corner |
- Engine switch is on (IG).
- Intuitive parking assist system is on.
- Shift lever in any position other than P.
- Vehicle speed is less than approximately 10 km/h (6 mph).
|
| Front Center |
- Engine switch is on (IG).
- Intuitive parking assist system is on.
- Shift lever in any position other than P or R.
- Vehicle speed is less than approximately 10 km/h (6 mph).
|
| Rear Corner |
- Engine switch is on (IG).
- Intuitive parking assist system is on.
- Shift lever is in R.
- Vehicle speed is less than approximately 10 km/h (6 mph).
|
| 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:
- Allocation refers to the process of the clearance warning ECU assembly setting aside IDs for the sensors.
- The vehicle has the sensors arranged in 2 groups. There is a front
series and a rear series. The sensors are connected in a "daisy chain".
(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.
