On the Signal Check screen, it is possible to check if the signals sent to the parking assist ECU are normal.
On the Signal Check screen, "OK" (blue) is displayed for items with a normal inspection result or input state.
On the Signal Check screen, "CHK" (red) is displayed for items with an abnormal inspection result or input state.
Displayed items may differ depending on vehicle specifications.
| Item | Signal Input Method | Detail | DTC Output when Abnormal Result is Displayed | Signal Receiver |
|---|---|---|---|---|
| CAN | CAN communication | CAN communication signal | DTC is output | Related ECUs |
| CAMERA SW | Vehicle wire harness | Panoramic view monitor switch signal input state | DTC is not output | Panoramic view monitor switch |
| SHIFT | Vehicle wire harness | Shift position switch signal | DTC is not output | BKUP LP relay |
Depending on the parts that are replaced or operations that are performed during vehicle inspection or maintenance, calibration of other systems as well as the panoramic view monitor system may be needed.
Check which items display on the signal check screen.
