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 (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 PCM (Pin 6 of C-connector)
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 (see the TIRE CALIBRATE diagnostic screen).

BACK-Reverse indication from taillight relay (Pin 5 of C-connector)
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.

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" using the "+" button. The CAN bus passes this information from the gauge control module to the navigation control unit.

NOTE: This setting is unaffected by the "display mode" hard button located below and to the left of the interface dial.

ILL-Illumination Indication
(Pin 5 of navigation unit A-connector)
1. OFF (0) when parking lights, or headlights are off
2. ON (1) when parking lights, or headlights are off

This signal is used by the navigation unit to determine whether to put the navigation screen into the Day or Night brightness mode (Setup screen 1).

DVD Lid-senses if DVD door is open
1. (Close) when door is closed
2. (Open) when door is open

The navigation unit has a micro switch to detect this. If open is indicated when the door is closed, replace the navigation unit.
