Failure Display Mode/Fault Codes
The VS-400 performs internal diagnostics at power-up, then continuously monitors system components thereafter.
If a failure is detected, depending on what features are affected, the DIU displays a screen similar, see Fig., blinks the orange fault light, and sounds a tone. Press the OK button to acknowledge the fault.
Fig. 1, Fault Display, VORAD
After the fault has been acknowledged by the driver pressing the OK button, the DIU will attempt to return to normal operations. The orange LED is continuously illuminated while the fault persists. If the fault disappears, the VS-400 transmits a message to indicate that the fault status has changed to a previously active fault.
In the event the FLR antennae becomes blocked while the vehicle is moving (e.g., snow, mud, ice, tampering, etc.), the system sounds a tone and displays the fault screen, see Fig..

Previously active fault codes can be reviewed, tested, and cleared using the Eaton Service Ranger diagnostic tool. Contact an authorized Freightliner dealer to review and clear previously active fault codes. See Fig. for common fault codes.
