Evaporative Emissions System

This trainer demonstrates the live operation and study of a late-model General Motors enhanced evaporative emissions (EVAP) system. The trainer will run the GM Service Bay EVAP Test using either it’s built- in scan tool or a Tech 2TM.

Realistic EVAP system faults, including system leaks, can be inserted via a built-in keypad, a local computer or via the optional ATech Lab System (ALS) to give students troubleshooting practice. Students follow manufacturer’s diagnostic procedures when troubleshooting system faults. Diagnosing system leaks is enhanced by the clear hoses when using a smoke machine. Tech 2TM and smoke machine are NOT included with the trainer. Includes courseware.
