Car Status
Use this screen to confirm that the audio-navigation unit is properly receiving input signals. Signals equal to (0) are OFF, and signals equal to (1) are ON. If the value on the display does not match the actual vehicle status, then check the wire carrying the signal.
- VSP-Vehicle Speed Pulse from the ECM/PCM (audio-navigation unit connector A (24P) terminal No. 15)
The VSP comes from the ECM/PCM as a dedicated signal. Internally, the audio-navigation unit compares the actual VP on the map against street data to adjust the pulse to speed scaling factor.
- OFF (0) when the vehicle is not moving
- ON (1) when the vehicle is moving
- BACK-Reverse indication from reverse relay (audio-navigation unit connector D (20P) terminal No. 2)
The BACK signal is used by the audio-navigation unit to allow the map screen to show the VP moving backwards when the vehicle is in R. This signal is needed because the VSP has no direction indication.
- OFF (0) when the shift lever is in any position other than R
- ON (1) when the shift lever is in R
- ILL-Illumination Indication
The illumination indication comes from the gauge control module to the audio-navigation unit via the B-CAN bus.
The navigation uses the signal to determine whether to put the navigation screen into the Day or Night brightness mode (Setup screen 1).
- OFF (0) when parking lights, or headlights are off
- ON (1) when parking lights, or headlights are on
- ILL CANCEL
The illumination cancel indication comes from the gauge control module to the audio-navigation unit via the B-CAN bus.
This item detects whether the illumination cancel function is in use.
- OFF (0) when the dashlights brightness control knob is less than 90 % brightness with the headlights turned on
- ON (1) when the dashlights brightness control knob is more than 90 % brightness with the headlights turned on
