Frequently Asked Questions
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.
Are vendors required to update or register each different configuration of hardware, even though the product is the same as an application (APP) (e.g., black box and Samsung, black box and iPhone, black box and Nexus)?
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.
