The BMW E46 Central Locking System

The following schematic depicts the BMW E46 3 Series Central Locking System Wiring and Circuit Diagram.

The BMW E46 Central Locking System Wiring and Circuit Diagram

The BMW E46 glove box is integrated into the scope of the central locking system on the E46iC. An additional actuator is positioned above the glove box to lock it whenever the central locking system is activated. Additionally, the trunk is locked out whenever the top storage cover is unlocked while the top is being raised or lowered. The top storage cover motor hall sensor signals the GM any time the cover is unlocked. The CVM receives a signal from the GM over the K-Bus, whenever the trunk is opened, which locks out the soft top operation. A micro switch on the glove box lock cylinder signals the GM to lock the trunk electrically for the valet key position. The trunk can only be opened mechanically with either FZV key or the wallet key. All other functions of the central locking system remain the same as the E46 Sedan and Coupe. The antenna  for the FZV system is incorporated with the receiver into the interior rear view mirror.
