Lesson 1: ZKE Systems - An Introduction

Lesson 1 looks at ZKE systems, the term used to describe the central body electronics of a BMW car, such as the engine management system, windscreen wipers, central locking and electric windows. Students will learn how these systems operate and how they exchange data, using systems known as 'bus networks', to ensure that modern cars are reliable and safe. 

At the end of this lesson students should be able to:

• Explain the requirements for bus systems
• Describe the decimal and binary systems
• Describe analogue transmission
• Describe digital transmission
• Identify BMW vehicles and major bus systems.
