Lesson 1: ZKE Systems - An Introduction

Cars use a variety of electrical devices and components, such as windscreen wipers, central locking, air conditioning, entertainment systems and electric windows. Together these are known as the central body electronics, or in BMW cars ZKE systems. These systems are important because they help to make a car safe and reliable and also improve the comfort for the driver and passengers.

In lesson 1 you will learn how ZKE systems operate and how they exchange data using systems known as 'bus networks'.

At the end of this lesson you 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.
