EVAP System and Components
"EVAP System and Components" looks at the construction and function of the Evaporative Emission Control (EVAP) system, including the On-board Refueling Vapor Recovery (ORVR) system. We will examine individual components, including the charcoal canister, the purge and vent controls and the various sensors and switches. The lesson will describe how each component works and how they all work together as one system, and it will cover the basic EVAP system as well as the NVLD, DSIM and DMTL systems.
Learn how the Powertrain Control Module (PCM) operates the EVAP system and checks for leaks and malfunctions. We will describe how a scan tool is used to diagnose trouble codes and to ensure the system is properly repaired before returning the vehicle to the customer.
Hybrid and Electric Vehicles: Braking Systems
Today, almost every manufacturer selling vehicles in North America offers at least one model with a hybrid-electric or all-electric powertrain. These vehicles require a highly sophisticated braking system. These vehicles have two separate but integrated braking systems - regenerative and hydraulic braking systems.
Hybrid and electric vehicles integrate these two technologies into one system operated by powerful computers using high-resolution sensors and sophisticated software. Coupled together with advanced electric motors and new battery technologies, the computer-controlled braking system is the third of three pillars that support all of today’s hybrid and electric vehicle designs.
This lesson will focus on hydraulic braking systems used on electric and hybrid-electric vehicles. We will discuss regenerative braking, computer-controlled hydraulic brakes, hydraulic- and electric-powered brake boosters and electric parking brakes. This course will highlight diagnostic and service procedures, essential calibration procedures and the tools required to complete this specialized work.
Advanced Driver Assist Systems (ADAS)
Since the early 2010s, manufacturers have begun incorporating ADAS, or Advanced Driver Assist Systems, technology into their vehicles. With promises of protecting drivers and reducing accidents, consumer demand is expected to increase exponentially. ADAS features can detect moving objects, alert drivers to potentially hazardous conditions, or in some cases, even slow down and automatically stop the vehicle. ADAS maintenance and repair offer technicians with new opportunities. After vehicle collision or even specific maintenance procedures, these systems need to be repaired and recalibrated to pre-collision conditions.
