INSPECT HEADUP DISPLAY (w/ Headup Display)
Test mode
| *a | DTCs are displayed |
| *b | DTCs are not displayed |
Diagnostic trouble code
Operate the headup display switch assembly to display the DTCs for the headup display.
Tech Tips
If any DTCs are displayed, this indicates that there is a communication malfunction with the combination meter assembly or the AVC-LAN.
| DTC | Malfunction Status |
|---|---|
| 01 | There is a loss of communication with the combination meter assembly (current malfunction). |
| 02 | There is a loss of communication with the combination meter assembly (past malfunction). |
| 03 | There is a loss of communication with the AVC-LAN (current malfunction). |
| 04 | There is a loss of communication with the AVC-LAN (past malfunction). |
Customize
Operate the headup display switch assembly to set the display function to ON or OFF.
Tech Tips
The audio display function can be customized when vehicle speed is below 8 km/h (5 mph) (the audio display function switches to normal control when the vehicle speed is 8 km/h [5 mph] or more).
| *1 | Switch is pressed and held | *2 | Switch is pressed and held, or is not operated for 3 seconds |
| *3 | Switch is pressed briefly | - | - |
