Garmin ELOG, Owner'S Manual

Diagnostics and Malfunctions

The Garmin eLog app records malfunctions and diagnostic events when the app detects critical functions that 
do not conform to Federal Motor Carrier Safety Administration (FMCSA) specifications. When a malfunction is 
detected, the driver and motor carrier are subject to responsibilities as directed by FMCSA guidelines.
Driver Responsibilities
• The driver must note the malfunction of the ELD and provide written notice of the malfunction to the motor 

carrier within 24 hours.

• The driver must reconstruct the Record of Duty Status (RODS) for the current 24-hour period and the previous 

7 consecutive days, and record the records of duty status on graph-grid paper logs that comply with 49 CFR 
395.8, unless the driver already has the records or retrieves them from the ELD.

• The driver must continue to manually prepare RODS in accordance with 49 CFR 395.8 until the ELD is 

serviced and returned to a compliant status.

Motor Carrier Responsibilities
• The motor carrier must correct, repair, replace, or service the malfunctioning ELD within eight days of 

discovering the condition or a driver's notification to the motor carrier, whichever occurs first.

• The motor carrier must require the driver to maintain a paper RODS record until the ELD is back in service.
