Ability Operation Mode
There is an ability operation mode for Fail-safes due to low or high ambiance temperature.
If HDD data can be read, fail-safe is shown, then normal displays are displayed only for functions which can be operated.
- The AV control unit diagnosis function starts up with multifunction switch operation and the AV control unit performs a diagnosis for each unit in the system during the on board diagnosis.
- Perform a CONSULT diagnosis if the on board diagnosis does not start, e.g., the screen does not display anything, the multifunction switch does not function, etc.
- The trouble diagnosis function has a self-diagnosis mode for conducting trouble diagnosis automatically and a confirmation/adjustment mode for operating manually.
- The self-diagnosis mode performs diagnoses on the AV control unit, connections between system components as well as connections between AV control unit and GPS antenna. Then it displays the diagnosis results on the display.
- The confirmation/adjustment mode allows the technician to check, modify or adjust the vehicle signals and set values, as well as to monitor the system error records and system communication status. The checking, modifying or adjusting generally require human intervention and judgment (the system cannot make judgment automatically).

ADDITIONAL SERVICE WHEN REPLACING AROUND VIEW MONITOR CONTROL UNIT: Description
Perform the calibrating camera image when replacing around view monitor control unit. Refer to " CALIBRATING CAMERA IMAGE (AROUND VIEW MONITOR): WORK PROCEDURE ".
CONFIGURATION (AV CONTROL UNIT): Description
- Since vehicle specifications are not included in the AV control unit after replacement, it is required to write vehicle specifications with CONSULT.
- Configuration has three functions as follows.
| Function | Description | |
|---|---|---|
| Read/Write Configuration | Before Replace ECU | Allows the reading of vehicle specification written in AV control unit to store the specification in CONSULT. |
| After Replace ECU | Allows the writing of the vehicle information stored in CONSULT into the AV control unit. | |
| Manual Configuration | Allows the writing of the vehicle specification into the AV control unit by hand. | |
PREDICTIVE COURSE LINE CENTER POSITION ADJUSTMENT: Description
Adjust the center position of the predictive course line of the rear view monitor if it is shifted.
CALIBRATING CAMERA IMAGE (AROUND VIEW MONITOR): Description
- Calibration must be performed after removing/replacing the cameras, removing parts (e.g. front grille, door mirror, and others) mounted on the cameras, or replacing the Around view monitor control unit.
- The use of CONSULT is required to perform calibration or writing of calibration results to the Around view monitor control unit.
- Align the white lines on the road near the vehicle at the boundary of each camera image by this camera calibration. The white lines far from the vehicle may not be aligned at the boundary of each camera image. The farther the line, the greater the difference is.
AV CONTROL UNIT: Description
CAN (Controller Area Network) is a serial communication line for real-time application. It is an on-vehicle multiplex communication line with high data communication speed and excellent error detection ability. Many electronic control units are equipped onto a vehicle, and each control unit shares information and links with other control units during operation (not independently). In CAN communication, control units are connected with 2 communication lines (CAN-H, CAN-L) allowing a high rate of information transmission with less wiring. Each control unit transmits/receives data but selectively reads required data only.
CAN Communication Signal Chart. Refer to " CAN COMMUNICATION SYSTEM: CAN COMMUNICATION SIGNAL CHART ".
