Power Supply

2011 BMW 740iSECTION Power Supply

The only external power supply to the ICM control unit is with terminal 30B. This is made available by the junction box electrical system and the fuse carrier at the front.

The electronics and integrated sensor system are therefore supplied inside the ICM control unit. Additionally, the ride-height sensors connected to the ICM control unit and the output stages for activation of the valves for the steering unit are also supplied.
