TRAD4101 - HEV/EV Preventative Maintenance and Repair

Course Description

Course description

This course is designed to familiarize the student with Hybrid and Electric vehicle safety, and system isolation of the Electric Machine and Internal Combustion Engine (ICE) to perform testing and maintenance procedures. Hands-on training to identify, disable and test for high voltage. Prepare vehicle for diagnostic testing and perform oil pressure checks, cooling system testing, and cylinder compression testing.
