Fleet Aftertreatment Systems Training

Master DPF, DOC, EGR, and SCR systems — the #1 cause of derates, limp modes, and roadside failures.

Why This Training Matters

  • Emissions faults cause more downtime than any other issue
  • A single DPF or SCR failure can cost $5,000–$15,000+
  • Dealer backlogs leave fleets stranded

What Techs Will Learn

  • Aftertreatment system operation & failure patterns
  • Forced regens, inducement resets, SCR efficiency testing
  • How to interpret soot %, differential pressure, NOx data
  • Diagnosing DEF issues: crystallization, dosing failures, contamination
  • Identifying root cause vs symptom fault codes

Hands‑On Labs

  • Live regen procedures
  • SCR troubleshooting using live data
  • Real‑world soot loading and pressure differential analysis

Outcomes

  • Fewer derates and roadside breakdowns
  • Thousands saved in avoided component replacements
  • Better uptime and emissions compliance

Give your team mastery over the most expensive system on modern engines.
