Terminal activation

WARNING: This page does not describe the selected car, but rather 21 other vehicles, including the 2006 BMW Z4, 2006 BMW M3, 2006 BMW M Roadster, 2006 BMW M Coupe, and 2006 BMW 550i. However, it is still accessible from the selected car via links, so may be relevant.

The CAS controls the following terminals on the ignition lock or START/STOP button and slot as follows:

Terminal R
To maintain the starting capability of the vehicle, the CAS shuts down terminal R automatically. Terminal R is shut down after 16 minutes if the driver's door is closed and no seat is occupied.
Terminal 15
The CAS controls terminal 15 = switched positive) for all electrical systems.
Terminal 15 wake-up wire
When terminal 15 is activated, the control units on the PT-CAN are activated (woken up) by the wake-up wire.
Terminal 50L and 50L_RS
During the starting procedure, terminal 50L is connected to the starter. Terminal 50R_LS is connected to the SMG control unit for clutch control.
Switched terminal 30g
Some consumers (e.g. RDC, SZM) are now on terminal 30g rather than directly on terminal 30. Terminal 30g is switched by the CAS. Shutting down the consumers on terminal 30g reduces the off-load current.
