Odometer Readings for American Mandate Not Matching

If the odometer readings for the American Mandate do not match, follow the steps below: 

1. Check that the Vehicle Gateway is correctly linked to the engine's ECM. The vehicle distance information can be acquired from the engine's ECM as specified in provision 4.2 of this Standard:
2. The Vehicle Gateway must monitor the engine's ECM’s odometer message broadcast and use it to record total vehicle distance information; and
3. The Vehicle Gateway must use the odometer message to determine the accumulated vehicle distance since the engine’s last power-on instance.

Note: You can also refer to pages 7-8 of the document from FMCSA confirming that the Vehicle Gateway should always use the ECM reading rather than the dashboard.
