Frequently Asked Questions
Does the registration process require companies to exclusively use FMCSA’s test procedure? Will vendors have access to testing facilities for ELDs?
No. ELD manufacturers may use any test procedure they choose and note this in the registration. FMCSA will not provide a third-party testing service. FMCSA will only investigate devices that are suspected of not conforming to specifications, and will conduct testing with the FMCSA compliance test procedure during its investigation.
How will CMV environmental specifics be tested with the ELD – for example, mounting and connections to the ECM?
How will the ELD report on-duty not-driving status when the origin of the duty status is automatic instead of driver-input?
The Event Checksum Calculation describes the individual items to be included in the calculation. Number 9 says “CMV Number.” Is this the CMV, VIN or the CMV Power Unit Number?
Is a physical connection between the ECM and ELD required in order to establish integral synchronization with the engine?
The manufacture must register each model and version and self-certify that each particular ELD is compliant with the ELD rule. The manufacturer must decide whether a firmware update is sufficiently significant to change the registration information. FMCSA did not specify parameters for version revisions.
