GREENSBORO, N.C. — Mack Trucks has reached a milestone with its GuardDog Connect, recently delivering its 25,000th truck equipped with the remote diagnostics system.

The truck, a Mack Pinnacle, was delivered to Cresson, Texas-based 3 Star Daylighting. GuardDog Connect was launched in 2014.

It monitors critical fault codes and gives the truck operator an early warning about issues that could result in downtime if gone unnoticed.

Mack claims the system has reduced diagnostic time by up to 70% and repair time by 21%.

GuardDog Connect is standard in Mack Granite, Pinnacle and Titan models as well as the TerraPro concrete pumper. The company’s Uptime Center in Greensboro, N.C. monitors fault codes remotely and then advises the operator or owner on the best course of action when a problem arises.

“I have used the GuardDog system twice so far, and it is very informative and keeps you up to date when issues arise,” said Aaron Hall, fleet manager for 3 Star Daylighting, which hauls waste water from oilfields in the Barnett Shale. “The trucks we used in the past completely relied on drivers and the information they gave me. I love how the OneCall customer service reps are friendly and willing to help with any issue, recommending a dealership in the immediate area for servicing the truck.”
