Kenworth has launched its TruckTech+ Over-The-Air system, which will provide the latest engine and aftertreatment software updates for Class 8 Kenworth trucks equipped with a 2017 or newer model year Paccar MX-13 or Paccar MX-11 engines.

The Kenworth TruckTech+ Over-The-Air system enhances uptime by offering fleet managers greater flexibility on when and where they can securely install software updates, according to the company.

“Kenworth TruckTech+ Over-the-Air is an important technology tool that provides the latest engine calibrations and updates to our customers, helping to increase uptime and promote enhanced fuel efficiency and performance,” said Laura Bloch, Kenworth’s assistant general manager for sales and marketing.

Customers with active Kenworth TruckTech+ subscriptions can access updates on the Paccar Solutions online portal or through the Paccar Over-The-Air mobile app, which is available from either the Apple App Store or Google Play Store.

The Paccar Solutions portal provides users with visibility to all their Kenworth trucks, performance data, and available software updates. Once the user approves the update, the system notifies the user when the download is ready for installation.

When the Kenworth truck is parked, a five-second press of the cruise control set switch connects the truck to the secure Paccar cloud server. The software update is then initiated through the Paccar mobile app, which allows monitoring of the download, and lets the user know when it is completed.
