Mack Trucks has activated its GuardDog Connect integrated telematics solution in more than 25,000 models since the product launched in 2014, the company announced.
The 25,000th truck was a Mack Pinnacle model delivered to Cresson, Texas-based 3 Star Daylighting, which hauls waste water from the oilfields in the Barnett Shale. Since Dec. 3, 3 Star Daylighting and its sister company Red Stag have purchased 30 Mack models. The company purchased an additional three years of coverage beyond the standard two years included in GuardDog.
GuardDog connect comes standard in Mack Granite, Pinnacle, Titan by Mack and TerraPro concrete pumper models and functions as a key component of Mack’s customer uptime support. Customer uptime support is managed through Mack’s Uptime center.
Earlier in the year, Mack expanded GuardDog Connect coverage to include the monitoring of fault codes for Mack mDrive and mDrive HD automated manual transmissions. Through Mack Fleet Management Services, Mack also allows customers to use the integrated GuardDog Connect telematics hardware with cloud-based intelligence software, currently provided through Telogis.
Mack recently expanded its partnered services offering to improve diagnostics results by integrating Mack ASIST with Truck Diagnostics System , a JPro-based software solution from Mack’s partner Noregon. Once TDS or JPro software identifies a vehicle fault, a service case is automatically opened in ASIST, providing the customer a quicker diagnosis.
“Mack GuardDog Connect’s success has proven that keeping customers’ trucks on the road through proactive management is far more valuable than responding to unplanned events after the fact,” said Stephen Roy, president of Mack Trucks North America.
