Car Status

Car Status

This screen is used 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 (Pin 6 of 8-Pin C-connector)
a. OFF (0) when vehicle is not moving
b. 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 the taillight relay (Pin 5 of 8-Pin C-connector)
a. OFF (0) when the shift lever is in any position other than reverse
b. 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, and to trigger the optional rear view camera. This signal is needed because the Speed Pulse does not provide any directional information to the system.

- ILL CANCEL
a. OFF (0) when the gauge assembly brightness control is not set to maximum brightness.
b. ON (1) when the gauge assembly brightness knob is at full bright.

The illumination cancel feature comes from the meter message in F-CAN.

- ILL-Illumination Indication
(Pin 5 of the navigation unit 20-Pin A-connector)
a. OFF (0) when the parking lights, or headlights are off
b. ON (1) when the parking lights, or headlights are on

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 the DVD door is open
a. (Close) when the door is closed
b. (Open) when the door is open

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