INTRODUCTION
The Central Body Electronics (ZKE III) equipped on the X5 includes the following sub-
systems under the total scope of its control:
• Windshield/tailgate wiping/washing,
including windshield rain sensor (AIC).
• Interior lighting
• Central locking
• Keyless entry
• Tailgate release
The following is an overview of new or changed features found on the X5 ZKE III variant.
• Passenger’s door module is now incorporated into the passenger’s door switchblock
module.
• Sunroof module (SHD) located on the K bus.
• The Central Locking system uses a new style door lock actuator with hall effect sensors
similar to E46.
• The GM III is responsible for the Key Memory feature. It provides the added
convenience of identifying users of the vehicle. Whenever the vehicle is locked or
unlocked via the FZV keyless entry system, a unique key identification signal (key
number) is transmitted to the General Module.
The key identification signal alerts the GM to communicate with other control systems
over the K Bus to store (when locked) or reset (when unlocked) certain driver adjustable
settings for the driver using the specific key. The GM also resets certain driver
adjustable settings that it controls directly.
• Power windows/Sunroof
• DWA alarm system
• Mirror - adjustment/memory/heating
