BMW CAS Car Access Systems Failures and Solutions
BMW vehicles are renowned for their performance, design, and advanced technology. However, E-Chassis models may experience issues with their CAS control units, also known as Car Access System control units.
These units serve as the immobilizer master in E-Chassis BMW vehicles, while in later F and G Chassis models, the CAS is integrated in other modules.
In this article, we will focus on E-Chassis vehicles and explore the benefits of Y Tech’s remanufactured CAS units with upgraded hardware.
Understanding BMW CAS Control Units and Terminals
The CAS control unit plays a vital role in your BMW, managing various operations, including terminal control. Here’s a quick recap of the key terminals in your BMW:
- Terminal 30: Provides constant battery power.
- Terminal 15: Activates ignition-on power after key authentication, controlled by the CAS.
- Terminal 50: Responsible for starter control.
A failing CAS module often results in a lack of terminal 15 and 50 functions, leading to performance issues and potential immobilization of the vehicle.
