Note
If "Recognition Camera/Target Position Memory" and "Recognition Camera Axis Adjust" are not performed, all of the systems using the pre-crash safety city sensor may be affected.
When the pre-crash safety city sensor has been replaced, or removed and reinstalled, "Recognition Camera/Target Position Memory" and "Recognition Camera Axis Adjust" must be performed.
When vehicle toe-in adjustment has been performed, "Recognition Camera/Target Position Memory" and "Recognition Camera Axis Adjust" must be performed.
When replacing the windshield glass with the pre-crash safety city sensor installed, make sure to replace it with a genuine windshield glass made for the pre-crash safety city sensor. Windshield glass assemblies other than genuine windshield glass assemblies made for the pre-crash safety city sensor do not have a camera installation bracket. Therefore, the pre-crash safety city sensor cannot be installed. If the camera is mounted on a windshield glass that is not a genuine windshield glass made for the pre-crash safety city sensor, none of the systems using the pre-crash safety city sensor may operate properly because of the opacity of the window glass and the shape of black ceramic parts.
Tech Tips
The pre-crash safety city sensor recognizes the white lines in relation to the vehicle on the basis of coordinates derived from the traveling direction of the vehicle. These coordinates differ for each vehicle depending on the tolerance and installation position of the pre-crash safety city sensor to the vehicle. Therefore, pre-crash safety city sensor beam axis adjustment must be performed individually for each vehicle.
RECOGNITION CAMERA/TARGET POSITION MEMORY
Before performing "Recognition Camera Axis Adjust", store the recognition camera position information, target position information and vehicle information in the pre-crash safety city sensor.
Tech Tips
For pre-crash safety city sensor adjustment procedures.
Perform adjustment with either "ONE TIME RECOGNITION" or "SEQUENTIAL RECOGNITION".

RECOGNITION CAMERA AXIS ADJUST
After storing the "Recognition Camera/Target Position Memory", further calibrate the stored data.
Tech Tips
Since there is an error in the internal data derived from the stored recognition camera position (horizontal and vertical coordinates, etc.), calibrating the internal data captured in the recognition camera improves the recognition sensitivity of the recognition camera.
For pre-crash safety city sensor adjustment procedures.
Perform adjustment with either "ONE TIME RECOGNITION" or "SEQUENTIAL RECOGNITION".

ENTER CONTROL MODE
When reproducing the problem symptom of the pre-crash safety system function, do not operate the pre-crash brake and only operate the warning (operations and buzzer sounding).
Tech Tips
When reproducing the problem symptom of the pre-crash safety system function, actually operating the pre-crash brake would be dangerous. To avoid this, when triggering operation of the pre-crash safety system function, do not operate the pre-crash brake and only operate the warning.
PCS IMAGE RECORD SETTING
Set the PCS image storage to valid or invalid.
Tech Tips
When the pre-crash brake operates, image data is stored in the pre-crash safety city sensor.
The stored image information cannot be viewed.
PCS IMAGE INFORMATION CLEAR
Clear the PCS image information stored in the pre-crash safety city sensor.
HISTORY CLEAR
When the history data status is "ON", clear the history.
