Heavy-Duty Vehicle Inspection Program (HDVIP)

Periodic Smoke Inspection Program (PSIP)


Participants in the course receive:

  • Hands-on training on the correct administration of the SAE J1667 Snap Acceleration Smoke Test Procedures for Heavy-Duty Diesel Powered Vehicles which is required under both smoke inspection programs;
  • Basic smoke emissions troubleshooting and repair; and
  • Assurance that your technicians will be up-to-date on California s heavy-duty vehicle inspection programs.

Diesel Exhaust After-Treatment and Maintenance (DEAM):

Diesel exhaust after-treatment technology including wall-flow diesel particulate filters (DPF) and selective catalytic reduction (SCR) systems are at the forefront of clean diesel technology.  CCDET’s Diesel Exhaust After-treatment Maintenance training covers the following:

  • background on why diesel particulate filters are necessary;
  • how the technology filters particulate matter (PM) and how regeneration strategies such as passive and active systems operate;
  • explores how filters might fail as well as preventative maintenance practices to avoid break downs;
  • an overview of SCR systems used on heavy-duty diesel engines.
