What Does Com Mean On Intoxalock

Overview

The term COM that appears on the display of an Intoxalock ignition interlock device is an abbreviation for “communication.” It indicates that the device is currently engaged in a data‑transfer or diagnostic process, such as uploading breath‑test results to the Intoxalock monitoring server, synchronising its internal clock, or performing a self‑check. While the COM status is active, the device typically does not accept a breath sample for a standard test, and the user may see a brief waiting period before normal operation resumes.

History / Background

Intoxalock, founded in 2001, pioneered the use of electronic breath‑alcohol testing units that are installed in a vehicle’s ignition system. Early models relied on wired connections to a central monitoring service, but as cellular and wireless technologies advanced, newer devices incorporated automatic communication capabilities. The COM indicator was introduced to inform users when the unit was establishing a connection with the backend system, a feature that became standard across most Intoxalock models released after 2015.

Importance and Impact

The COM status plays a crucial role in ensuring the reliability and legal compliance of the interlock program. By confirming that breath‑test data have been successfully transmitted, the device helps authorities verify a driver’s sobriety and maintain accurate records. The indicator also assists installers and service technicians in diagnosing connectivity problems, reducing downtime and the likelihood of false‑positive violations.

Why It Matters

For drivers subject to an interlock requirement, recognizing the COM message prevents confusion during routine testing. Misinterpreting the indicator as an error can lead to unnecessary service calls or missed appointments. Moreover, understanding COM helps program administrators monitor device health, enforce compliance, and address technical issues promptly.
