lighting time, etc.] according to the user operation via the screen.) |
- Navigation receiver assembly
- Radio and display receiver assembly
|
- Air conditioning amplifier assembly
- Main body ECU (multiplex network body ECU)
- Front power seat switch LH (power seat control ECU)
- Multiplex tilt and telescopic ECU
| 3 retries are performed (including the first time). |
The
customize options for items related to the main body ECU (multiplex
network body ECU), multiplex tilt and telescopic ECU and front power
seat switch LH (power seat control ECU) are not displayed or the
settings cannot be saved. | U0073
(Navigation receiver assembly/Radio and display receiver assembly) |
|
Combination Meter Cooperation function (Synchronizes
multi-media module and combination meter settings (language, unit,
accent color). The multi-media module sends navigation system
turn-by-turn, audio and telephone data.) |

|
Timestamp (Stores the timestamp information received from the CGW together with the DTC.) |
Airbag sensor assembly |
Central gateway ECU (network gateway ECU) |
When
a fail value is received or a communication stop occurs, a separate
count is changed to inside the ECU and separate count recognition
information is set. | - |
- |
| Collision Detection Signal
(Reports
a collision in order to perform a fuel cut, trigger the EDR, perform
MCB control or detect millimeter wave radar axis misalignment, etc.,
during a collision.) |

(Sends information about the passengers in order to turn the seat belt warning on and off.) |
- Main body ECU (multiplex network body ECU)
- Combination meter assembly
| Airbag sensor assembly |
Nothing | - |
- |
| Trigger Signal/Self Transmission
(Outputs the yaw rate and acceleration sensor signal.) |
Airbag sensor assembly |
Brake actuator assembly (skid control ECU) |
Sends yaw rate sensor information every 0.012 seconds |
- | - |
|
Event Data Recorder (EDR) (Records
conditions, such as the vehicle speed, the amount the accelerator is
depressed, and the shift lever position when the event data recorder
recording conditions are met.) | Airbag sensor assembly |
- Millimeter wave radar sensor assembly
- ECM
- Spiral with sensor cable sub-assembly (steering angle sensor)
- Brake actuator assembly (skid control ECU)
- Airbag sensor assembly
|
- An invalid value is recorded in the EDR.
- The previous values are maintained.
