Start stop technology is a growing option in most manufactures. This technology allows the engine to shut of when stopped at a red light and starts the engine when the gas pedal is applied. The electrical systems involved along with the starting motor systems have different operating characteristics than what most techs are used to. We will cover what and why this is used along with the electrical operation of different manufactures systems and diagnostics of no crank faults.
This class will feature the operations of today’s GDI systems. Most manufactures are offering a GDI engine in their car & truck lines. The class will detail safety, operations and diagnostics for these fuel delivery systems. It will include mechanical, electronic testing INCLUDING Labscope changes, and common fixes along with Tech Tips.
The class will be led through the design and operation of the modern Evaporative Emissions system. Recent system changes and additions will be covered. System operation and OBDII monitors will be discussed in detail. System testing will be stressed as will the testing of individual components. The use of diagnostic tools such as smoke machines and scanners are explained. Service bay tests and scan tool actuation modes will be thoroughly discussed. Finally, common faults, TSBs diagnostic tips and aids are shared.
Flashing is a term commonly used to describe the reprogramming of Electronic Control Modules (ECUs) on OBDII vehicles. These vehicles use modules (ECUs) that are electronically reprogrammable. This allows the manufacturer to make changes to the programming on a vehicle without replacing the module. When an update is required the new “Flash” files are retrieved from the vehicle manufacturer and loaded into the ECU. Prior to the implementation of the J2534 Standard this was done using the factory scan tool. In 2004 a Federal mandate required manufacturers of OBDII compliant vehicles to allow reprogramming of emissions related modules with a generic Pass Thru device. This made reprogramming available to the aftermarket at a reasonable cost. The goal of the mandate was to allow vehicle owners to service their vehicles outside the dealer network while still maintaining emissions compliance. Although the mandate is for emissions compliance some manufacturers make non-emissions flashes available. Having the ability to flash/reprogram modules on these vehicles can increase shop productivity and profit. We will also demonstrate the Flash/Reprogramming procedure on 3 popular manufacturers.
Welcome to the Labscope Operation and Pattern Interpretation Training class.
This class will range from the novice to advanced users. It will cover a wide aspect of labscope operation but more important actual diagnostics. It is not based on one type of manufacture.
Note: We are supplying Labscopes for the hands on portion of this class. You are welcome to bring your own Labscope to class.
