Zonar OTAir for Cummins Engine for iOS

By Zonar Free

Developer's Description

Reduce downtime and service center visits due to costly engine control module (ECM) updates with a convenient mobile app solution for fleet maintenance personnel and drivers. Zonar OTAir simplifies the calibration process for Cummins engines, reducing service downtime from up to three days to as little as five minutes.

Key features:

Simple interface with clear instructions

In-app QR code scanner for VIN validation

Software rollback feature if deployment issues occur

Status updates display on the app during the calibration process

How it works:

Firmware updates available on your vehicles engines are automatically downloaded through the Zonar V4 telematics box to the Cummins ECM. When its safe for the vehicle to be stationary, the driver:

1. launches the Zonar OTAir mobile app

2. scans the vehicles unique VIN QR code (or enters it manually)

3. approves the calibration to begin the update

Thats it. Your Cummins-powered vehicle will be back on the road in minutes.
