This handout is representative of selected 4, 6, 8, and 12 cylinder Engine Management Systems from 1996 to present. The handout serves two purposes; Instructor lead training and “stand alone” system reference material for the BMW Technician. Obviously, all of the material in the handout can not be covered in 5 days, therefore a system will be selected to cover the basic required information. The information from other systems will cover the differences or variants that make them unique. Where possible, use the latest diagnostic equipment and DISplus/MoDIC software programs.Objectives
The Instructor will familiarize the BMW Technicians with an understanding of the current Engine Electronics Systems and diagnostic skills. Also the Technicians will perform hands on practicals in the shop to ensure participation in diagnosis and component testing. Objectives are provided on page 2 of each system to guide you to the key learning points of each module. Review questions are provided at the conclusion of each module to verify that you achieve the learning objectives during the course. A final test will be given at the end of the course. It is very important to study the content which will assist you with important “on the job” information and successful completion of this course.
