20 MAY 2026 SERVICE TRUCK PULSE SERVICE TRUCK PULSE MAY 2026 21 TECHNOLOGY CRANES, COMPRESSORS, AND WELDERS JOIN THE CONVERSATION The next frontier is the equipment mounted on the truck itself. Cranes, air compressors, generators, and welding units are increasingly equipped with sensors, telematics modules, and cloud connectivity. • Cranes: Stellar Industries, for example, offers its Stellar Telematics system, which provides remote monitoring of crane usage, load cycles, and maintenance intervals. Stellar noted that the system “helps identify issues before they become downtime events” and allows fleet managers to “monitor equipment health from anywhere.” • Compressors: VMAC’s G30 and DTM compressor lines now integrate telematics-ready control systems. VMAC has publicly stated that its advanced digital controls “provide real-time performance data” and help operators “identify maintenance needs earlier.” • Welding Units: Lincoln Electric’s CrossLinc and ArcLink systems allow remote monitoring of welding parameters and machine status. Lincoln Electric said that connected welding systems “enable remote diagnostics and reduce the need for on-site troubleshooting.” These capabilities mean the service truck is no longer just a platform—it’s a connected ecosystem where every component can report its status. UPDATES MOVE BEYOND THE ENGINE While engine control modules (ECMs) were the first targets for OTA updates, the technology is spreading across the truck. Ford has used OTA updates to improve trailer brake controllers, camera systems, and even instrument cluster interfaces. GM has pushed updates to its Super Cruise driver-assist system and infotainment modules. Ram and Stellantis have used OTA updates to patch software vulnerabilities and improve powertrain calibration. For vocational fleets, the most valuable updates are those that: • I mprove aftertreatment performance; • A ddress false diagnostic codes; • E nhance PTO or idle‑management logic; • U pdate safety or stability‑control systems, and; • I mprove battery management on hybrid or electric service trucks These updates can prevent unnecessary shop visits—a major advantage for fleets operating in remote or rural areas. No kidding, downtime is expensive. A report from the Technology & Maintenance Council (TMC) and FleetNet America found that the average roadside repair for a commercial vehicle costs more than $500 in direct expenses, not including lost productivity. While service trucks aren’t long‑haul tractors, the principle is the same: every hour a truck is down is an hour it’s not generating value. Remote diagnostics helps fleets avoid those surprises. By identifying issues earlier, fleets can schedule repairs during planned downtime rather than reacting to failures in the field. Cummins, one of the earliest adopters of remote diagnostics, has publicly stated that its Connected Diagnostics platform can “reduce diagnostic time by up to 50 percent” and help fleets “avoid unnecessary service visits.” For service fleets that operate in harsh environments such as mines, oilfields, and construction sites, that reduction is significant. BETTER PREPARED = FASTER REPAIRS Remote diagnostics doesn’t just identify problems; it helps technicians arrive with the right tools, parts, and expectations. Navistar’s OnCommand Connection platform, which is freely described on its website, provides fault-code action plans that guide technicians through likely causes and recommended repairs. Navistar states that the system “helps technicians diagnose issues faster and more accurately” and “reduces time spent on troubleshooting.” For service fleets with mixed equipment, this is especially valuable. A technician servicing a crane one day and a welder the next can rely on remote data to understand what’s happening before they arrive. Remote diagnostics is reactive—it tells you when something is wrong. Predictive maintenance is proactive—it tells you when something will go wrong. Telematics providers like Geotab, Samsara, and Verizon Connect all offer predictive maintenance tools that analyze patterns in engine data, fluid temperatures, vibration signatures, and component cycles. Geotab stated that predictive analytics can “identify developing issues days or weeks before a fault code appears” and “significantly reduce unplanned downtime.” TECHNOLOGY As cranes, compressors, and welders become more connected, predictive maintenance will extend to hydraulic pumps, air ends, bearings, and electrical components. It’s worth noting that as trucks become more connected, cybersecurity becomes a new form of preventive maintenance. The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has already publically warned that connected vehicles “increase the attack surface” and require “ongoing software updates and security patches.” OTA updates are part of that defense. By keeping software current, fleets reduce vulnerabilities that could compromise vehicle systems or fleet data. ELECTRIC SERVICE TRUCKS ACCELERATE THE TREND Battery‑electric service trucks—a still-emerging technology, but gaining traction—rely heavily on software. Their drivetrains, battery packs, thermal systems, and charging interfaces are all software‑controlled. Rivian, which supplies electric chassis for some upfitters, has publicly stated that OTA updates allow the company to “improve performance, efficiency, and functionality over time.” Ford has made similar claims about the F‑150 Lightning Pro, noting that OTA updates “enhance vehicle capability and uptime.” While Rivian is still in business and continues building and selling its R1T, R1S, and commercial delivery vans, it is preparing for its next-generation, more affordable R2 platform. Ford, on the other hand, has ended production of the current all‑electric F‑150 Lightning, including the Pro work‑truck variant, in late 2025. Though it claims it will relaunch a new extended‑range electric (EREV) version in the future. Additional EV manufacturers are also leaning heavily on OTA capabilities. GM’s BrightDrop division notes that its Ultifi software platform enables “continuous improvement through over‑the‑air updates” and allows the company to “diagnose issues remotely and, in some cases, repair them without a dealership visit.” Blue Arc, The Shyft Group’s commercial EV brand, said that its electric Class 3–5 platforms use a proprietary software and telematics system that supports OTA updates to “enhance vehicle performance and uptime.” Bollinger Motors, which is developing its B4 Class 4 chassis cab for fleet upfitters, describes the truck as a “software‑defined vehicle” designed to receive performance and feature updates over the air. Canadian manufacturer Lion Electric makes similar claims about its Lion5 electric truck, noting that OTA updates allow the company to continuously improve performance and functionality. For electric service trucks, OTA updates aren’t a convenience—they’re essential. CHALLENGES AND LIMITATIONS Despite the benefits, remote diagnostics and OTA updates aren’t magic. 1 Not every issue can be fixed remotely: Mechanical failures still require hands-on repair. A cracked hydraulic hose or worn-out bearing won’t fix itself. 2 Connectivity can be a barrier: Rural fleets may struggle with weak cellular coverage. Some OEMs allow updates via Wi‑Fi, but that requires trucks to return to a depot. 3 Data overload is real: Fleets can be overwhelmed by fault codes and alerts. The platforms that prioritize severity and provide action plans are becoming essential. 4 Training is required: Technicians must understand how to interpret remote data and integrate it into their workflow. The next phase of remote diagnostics will likely include: • C omponent‑level OTA updates for cranes, compressors, and welders; • A I‑driven predictive models that learn from fleet‑specific data; • R emote calibration of sensors and control modules; • A utomated maintenance scheduling based on real‑time usage; Integration with digital service manuals and AR repair tools. In other words, the service truck will continue evolving into a smart, self‑aware machine. Keep in mind, however, that remote diagnostics and OTA updates won’t eliminate downtime, though they can and are reducing it, making maintenance more predictable. For service fleets, that means more jobs completed, fewer emergency repairs, and a clearer picture of equipment health. The truck may not fully fix itself yet, but it can certainly tell you what’s wrong — and increasingly, it can update its own software to keep working.
