ELD Unplugs

The ELD Unplugs page tracks instances where an ELD (Electronic Logging Device) loses its connection with the vehicle or the RouteMate mobile app. Monitoring unplugs is important for maintaining accurate records and staying compliant with federal regulations.

What Are ELD Unplugs?

An ELD unplug occurs when the ELD device stops communicating with the vehicle’s engine computer (ECM) or the RouteMate mobile app. This can happen for a variety of reasons:

The ELD device is unplugged from the vehicle’s diagnostic port.
The Bluetooth connection between the ELD and the driver’s mobile device is lost.
The ELD device loses power or malfunctions.
The vehicle’s diagnostic port has an intermittent connection.
The driver’s phone or tablet runs out of battery or is turned off.

When an unplug occurs, the ELD cannot record driving data, which creates a gap in your compliance records.

Why Unplugs Matter for Compliance

Federal Hours of Service (HOS) regulations require that ELD devices maintain a continuous connection during vehicle operation. When disconnects occur:

Gaps in driving records — The ELD cannot log duty status changes, driving time, or vehicle movement during an unplug, which can result in incomplete or inaccurate driver logs.
Compliance risk — During a DOT inspection or audit, unexplained gaps in ELD data can raise red flags and may result in violations.
Data integrity — Frequent disconnects can undermine the reliability of your fleet’s HOS records, making it harder to verify that drivers are operating within legal limits.

Note: The FMCSA requires that ELD malfunctions and data diagnostic events be reported and addressed within a specific timeframe. Persistent disconnect issues should be treated as potential ELD malfunctions.

Viewing Unplug Events

How to view ELD unplugs:

Navigate to ELD Events and then ELD Unplugs.
You will see a list of all unplugged events across your fleet, with the most recent events at the top.
Each entry shows:
- Vehicle — The vehicle where the disconnect occurred.
- Driver — The driver assigned to the vehicle at the time of the disconnect.
- Start time — When the ELD lost connection.
- End time — When the connection was restored (if applicable).
- Duration — How long the disconnect lasted.
Use the filters to narrow the list by vehicle, driver, or date range.
Click on any unplugged event for more details.

Tip: If you notice a pattern of disconnects for a specific vehicle, the issue is likely hardware-related (a faulty ELD device, loose diagnostic port, or wiring problem). If disconnects follow a specific driver across multiple vehicles, the issue may be related to the driver’s mobile device or behavior.

Disconnect Duration and Frequency

Understanding how often and how long disconnects occur helps you assess the severity of the issue.

Duration

Brief disconnects (under a few minutes) — These may be caused by momentary signal loss, vehicle vibration, or brief Bluetooth interruptions. They are common and usually not a concern unless they happen repeatedly.
Extended disconnects (several minutes to hours) — These are more concerning and suggest a persistent hardware or connectivity issue that needs to be investigated.

Frequency

Occasional disconnects — A disconnect here and there is normal, especially in vehicles that operate in areas with poor connectivity or rough terrain.
Frequent disconnects — If the same vehicle or driver experiences disconnects regularly, you should take action to identify and resolve the root cause.

Tip: Create a routine to check the ELD Unplugs page weekly. Addressing disconnect patterns early prevents them from becoming compliance problems during audits.
