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 (Dare 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 ECM/PCM (Audio-navigation unit connector A terminal No. 15)
- OFF (0) when vehicle is not moving
- ON (1) when vehicle is moving
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. As this scaling factor becomes more accurate, the Level gradually increases from 0 to 10 (see the Tire Calibrate Diagnostic Screen).
- BACK-Reverse indication from taillight relay (Audio-navigation unit connector C terminal No. 5)
- OFF (0) when the shift lever is in any position other than reverse
- ON (1) when the shift lever is in reverse
The Back signal is used by the audio-navigation unit to allow the map screen to show the VP moving backwards when in reverse. This signal is needed because the Speed Pulse has no direction indication.
- IGNITION-Ignition Switch Position Indication (Audio-navigation unit connector A terminal No. 14)
- OFF (0) when the ignition switch position is LOCK (0)
- ON (1) when the ignition switch position is ON (II)
- ILL-Illumination Indication
(Audio-navigation unit connector A terminal No. 13)
- OFF (0) when parking lights, or headlights are off
- ON (1) when parking lights, or headlights are on
The navigation uses the signal to determine whether to put the navigation screen into the Day or Night brightness mode. (Setup screen 1)
ILL CANCEL
This item detects whether the illumination cancel function is in use.
- OFF (0) if illumination cancel is not selected
- ON (1) if illumination cancel is activated
The illumination cancel function is activated by increasing the dash brightness to MAX.
