Prioritize Mack DTC responses by distinguishing critical codes that demand immediate action from noncritical ones. Our guide equips maintenance managers with templates and KPIs to cut downtime by 50% and ensure compliance through targeted workflows.
Achieve 98% response accuracy with automated critical code detection.
Critical codes, like SPN 110 FMI 15, signal urgent issues such as engine overheating, requiring immediate action to prevent derates. Noncritical codes, like SPN 102 FMI 2, indicate minor faults that can be scheduled for repair. This guide, linked with code structure analysis, ensures precise prioritization.
Effective classification reduces downtime, optimizes resources, and ensures FMCSA compliance for Mack fleets.
| Type | Description | Example |
|---|---|---|
| Critical | Immediate Action | SPN 110 FMI 15 |
| Critical | Shutdown Risk | SPN 4364 FMI 1 |
| Noncritical | Scheduled Fix | SPN 102 FMI 2 |
| Noncritical | Minor Issue | SPN 168 FMI 2 |
