General Vehicle Electrical: Introduction

The general vehicle electrical system of the E83 is for the most part based on the central body electronics 5 ZKE 5 of the E46.

The functions of the general vehicle electrical system are comparable to those of the general vehicle electrical system on the E46:

• Central locking
• Power windows, different to the E46
• Wipe/wash system
• Anti-theft alarm system
• Interior Lights
• Consumer shutdown
• Remote control operation
• Door mirror control
• Car and Key Memory

The GM5RD communicates with the following components on the LIN bus:

• Door mirror, driver
• Door mirror, passenger side
• Switch block, driver

The stored positions of the door mirrors are lost if the GM5RD is replaced.
