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)

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 (see the TIRE CALIBRATE diagnostic
screen).
BACK-Reverse indication from taillight relay (Pin 5 of 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. This signal is needed because the Speed Pulse has no direction indication.
