CNH has announced new software updates for its emissions systems designed to align equipment with updated EPA guidance on fault inducement timing. These updates are intended to provide operators with a longer window to plan and complete necessary repairs before an engine derate is initiated.
Why it matters
By adjusting the timing for fault inducements, these updates help prevent unexpected operational disruptions and costly engine derates during critical work. The change ensures operators have more control over the timing of their equipment maintenance and repairs.
The rollout begins in the fourth quarter of 2026, focusing first on high-horsepower agricultural equipment. Availability will expand across additional product families throughout 2027.
The players
CNH
A major manufacturer of agricultural and construction equipment known for integrated software and emissions-compliant engine systems.
EPA
The federal agency that establishes emission standards and regulatory guidance for heavy-duty engines and machinery across the United States.
The details
The software updates adjust the specific timing for emissions-system fault inducements. Customers who maintain a CNH Electronic Service Tool subscription have the option to perform the software update independently. Alternatively, CNH dealers are available to provide installation support either remotely or through on-site service visits.
Timeline
September 16, 2026: CNH announced the upcoming software updates.
Q4 2026: The initial software update rollout begins.
2027: Software availability expands to additional equipment applications.
The Home Front
This update reflects ongoing adjustments to machinery performance standards governed by EPA guidance on fault inducement timing. Manufacturers continue to balance regulatory compliance with the practical operational needs of equipment owners.
If you own CNH agricultural equipment, monitor your fleet for availability updates starting in late 2026. If you have an active Electronic Service Tool subscription, plan to verify your equipment status when the rollout begins.
The takeaway
These software updates offer operators a more predictable maintenance schedule for emissions systems by extending the time before engine power is reduced. Owners should prepare by confirming if their current models fall within the high-horsepower agricultural category for the Q4 2026 release.
