BMW xDrive Transfer Case CAN Controller — ATC350 / ATC35L / ATC450 / ATC45L

A drop-in replacement PCB for the longitudinal (linear) torque module, giving you full CAN bus control of the transfer case clutch actuator. It mounts in the factory module location, drives the OE actuator motor, and lets an aftermarket ECU command torque split directly over CAN — no FlexRay gateway or donor-vehicle coding required. Compatibility: Magna Active Transfer Cases fitted with the Continental longitudinal torque module — ATC350, ATC35L, ATC450 and ATC45L (BMW sedans/X1, and X3/X4/X5/X6 respectively). Replaces both the CAN and FlexRay factory module variants. Before ordering, confirm your transfer case is fitted with the Continental-made module. Not every unit in this family carries it, and the PCB is designed specifically to interface with the Continental actuator — check the module markings/connector against the compatibility list before purchase or installation. Included DBC files allow for you to develop your own control scheme.
