On-Site Service Warranty

Calibration work delivered on-site carries the same tuning warranty as ship-in or remote work. The on-site context adds some specific considerations — verification at delivery, travel-related logistics for follow-up, fleet relationship terms — that this policy covers.

The Core Warranty Is The Same

On-site calibration work carries the same tuning warranty as ship-in or remote calibration. Same coverage scope, same exclusions, same warranty period (stated in your service confirmation), same reflash policy. The service method changes; the warranty principle doesn't.

What does change is the operational context of follow-up work. Ship-in and remote follow-ups happen via the standard service ticket and reflash workflows. On-site follow-ups can happen via ticket, via ship-in, via remote (where supported), or via scheduled on-site re-visit depending on what fits the situation.

On-Site Verification Before The Technician Leaves

Every on-site programming session ends with a verification pass on each truck programmed during the visit. The technician confirms calibration parameters loaded correctly, runs the standard QA sequence for the platform, and confirms operational baseline before signing off on that truck. For fleet visits, the final fleet walkthrough with your fleet manager happens before the technician leaves the yard.

This matters because some issues are best caught while the technician is still on site. A truck that fault-codes during verification can be retried, re-loaded, or escalated to deeper diagnostic immediately. After the technician leaves, follow-up work has to route through one of the other service methods.

For fleet customers, the verification documentation goes to your fleet maintenance system as part of the standard on-site visit close-out. Truck VIN, work performed, calibration scope, verification result. This documentation supports any future warranty conversation.

Post-Visit Issues — How Follow-Up Works

When an issue arises after the on-site visit and falls within warranty scope, follow-up routing depends on the situation:

Single truck, supported platform, time-sensitive: Remote programming session is typically the fastest path. If your platform supports remote (Cummins INSITE-compatible, Paccar Davie4-compatible), we connect, diagnose, and reflash without scheduling another on-site visit. Same warranty applies; no charge for warranty-covered work.

Single truck, ship-in is acceptable: Pull the ECM, ship to us, we work through the issue, ship it back. Standard ship-in turnaround applies; warranty covers the calibration work, you cover the shipping.

Multiple trucks needing reflash, South Florida: Schedule a follow-up on-site visit. South Florida visits have no travel premium, so the economics work for multi-truck follow-up even on a small batch.

Multiple trucks needing reflash, nationwide fleet: Travel for nationwide follow-up visits is typically quoted separately even when the underlying calibration work is warranty-covered. The calibration work is free under warranty; the travel logistics are billable. We'll usually work with the fleet to batch follow-up work into a scheduled re-visit if the timing allows, rather than running a one-truck emergency travel cycle.

Fleet Relationship Warranty Terms

For fleet customers operating under structured service relationships — recurring on-site cadence, dealer program engagement, multi-year service contracts — warranty terms are typically customized as part of the relationship rather than following the standard policy. Common patterns:

Extended warranty period: Standard warranty period may be extended for fleet customers operating under ongoing relationship terms. The extension reflects the operational continuity and the lower diagnostic friction of working with a fleet we know.

Built-in reflash allowance: Annual reflash allowance per truck covered under the fleet relationship, with additional reflashes at fleet rate. The allowance gives fleet maintenance teams predictable budgeting for calibration adjustments.

On-site re-visit cadence: Scheduled follow-up visits at quarterly or semi-annual cadence to address warranty work, calibration refinement, and new work in a single trip. Travel covered under the relationship rather than per-visit.

Fleet relationship terms get worked out during the relationship setup conversation. For prospects considering fleet-level engagement, see the dealer inquiry or on-site visit booking paths to start the conversation.

Travel-Related Exclusions

The warranty covers calibration work. It does not cover travel costs for follow-up visits even when the underlying calibration work is warranty-covered. This is the one specific area where on-site warranty operates differently than ship-in or remote warranty.

The reasoning is straightforward: travel is a logistics cost, not a calibration cost. A reflash that's 30 minutes of calibration work shouldn't carry $2,000–5,000 of travel cost in the warranty obligation. Travel logistics are quoted separately for nationwide on-site work in the original quote, and they're quoted separately for follow-up work.

South Florida follow-up visits don't carry travel premium, so the warranty work is fully covered for South Florida fleet customers. For nationwide fleet customers, we'll often work to batch follow-up work into scheduled re-visits so travel costs are amortized across multiple trucks rather than allocated to a single warranty truck.
