Car Status

Use this screen to confirm that the 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 PCM (Navigation unit connector A (8P) terminal No. 6)
1. OFF (0) when vehicle is not moving
2. ON (1) when vehicle is moving

The VSP comes from the PCM as a dedicated signal. Internally, the 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.

BACK-Reverse indication from taillight relay (Navigation unit connector A (8P) terminal No. 5)
1. OFF (0) when the shift lever is in any position other than reverse
2. ON (1) when the shift lever is in reverse

The Back signal is used by the 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 (Navigation unit connector A (8P) terminal No. 1 and No. 2)
Detects if the engine is running using information provided over the F-CAN bus.
1. OFF (0) when the ignition switch position is ACCESSORY (I)
2. ON (1) when the ignition switch position is ON (II)
ILL-Illumination Indication (Navigation unit connector B (32P) terminal No. 5)
1. OFF (0) when parking lights, or headlights are off
2. 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. The F-CAN bus passes this information from the gauge assembly to the navigation unit.

NOTE: This illumination cancel function is turned off when the display mode hard button is used. The button is located below and to the left of the interface dial. The illumination cancel function is turned on when you cycle the key.
