There is no single universal list of every “ELD violation code” across roadside inspection, carrier review, and vendor interfaces. First identify whether the code is an FMCSA malfunction/diagnostic event, an HOS violation, an inspection-system code, or a vendor message.
What this means for your fleet
Build a code-resolution sheet with four fields: exact code and screen, issuing system, driver and vehicle context, and authoritative source. Preserve screenshots before clearing or restarting anything.
First classify the code
| What the screen or report shows | Category | Next authority |
|---|---|---|
| Power, engine synchronization, timing, positioning, data recording, transfer, or unidentified-driving indicator | ELD diagnostic or malfunction class | Installed-device manual plus FMCSA malfunction guidance |
| Driving beyond an HOS limit or missing required rest | HOS exception or violation analysis | Current 49 CFR Part 395 rule and carrier compliance review |
| Roadside inspection or enforcement-system code | Inspection result | Inspection report and issuing authority |
| Vendor-only alert or error message | Product support event | Exact provider documentation and support ticket |
There is no safe universal “ELD violation code” list. Preserve the exact code and wording before clearing or restarting the system.
What to check
Use these checks before changing a log, policy, device, integration, or buying decision.
| Check | How to verify |
|---|---|
| 1. Capture the exact code and wording | Capture the exact code and wording, icon or report, screenshot, date/time, driver, vehicle, device/app versions, and affected function before restart. |
| 2. Identify the issuing system | Retain the product, ELD event detail, inspection report, HOS screen, or vendor system that issued it, plus source identifier and owner. |
| 3. Check event time and vehicle | Keep event time, vehicle/VIN, driver, duty record, operating context, surrounding events, location, assignment, and preserved original. |
| 4. Separate HOS from device health | Classify the item against the current HOS provision, ELD malfunction/diagnostic definitions, inspection report, or vendor manual; record reviewer and result. |
| 5. Use the official guidance or device manual | Save the exact authoritative guidance or installed manual section, required response, notice or repair path, completed action, cleared result, and retest. |
Common failure modes
- Publishing an invented universal code list.
- Confusing warnings with citations.
- Restarting before evidence capture.
Limits and exceptions
This guide does not decide a fact-specific legal exception, certify a record, or guarantee a compliance, safety, cost, or audit outcome. Keep the original ELD record and any edit history. Use the current official rule for applicability and the exact installed-device manual for screen-by-screen actions.

Verify the rule and the installed workflow
Bring the exact device registration, installed manual, app version, carrier policy, and one example record. Factor ELD can demonstrate its current product; rule applicability remains a fleet compliance decision.
