Car Status

Car Status




Use this screen to confirm that 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 ECM/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 ECM/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 shift lever is in any position other than reverse
b. ON (1) when 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 activate the real-view camera. This signal is needed because the Speed Pulse has no direction indication.

This signal is obtained off of the F-CAN bus. For problems, perform F-CAN troubleshooting. The HDS (Honda Diagnostic System) can retrieve diagnostic trouble codes (DTCs) for the F-CAN.
- ILL-Illumination Indication
(Pin 5 of navigation unit A-connector)
a. OFF (0) when parking lights, or headlights are off
b. 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
a. (Close) when door is closed
b. (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.
