Switch-on Performance
The HUD receives the terminal 30 ON status via the K-CAN. The HUD is partially ready for operation from terminal R ON. That means that:
- The HUD can communicate with the other electrical-system devices via the K-CAN
- The TFT projection display is initialized and blanked
- The LEDs are off.
The HUD receives the terminal 15 ON status via the K-CAN. The HUD is ready for operation from terminal 15 ON. This permits the following actions:
- Switching on of the backlighting by the button on the BAFAS
- HUD height adjustment
- Adjustment of HUD brightness
- Display of information via the HUD.
When the vehicle is started, the vehicle is set to terminal 50 status. In terminal 50, i.e. Lights Off, the HUD goes into a hold status. This hold status is maintained until shortly after the end of the terminal 50 status.
