The IPC displays are dimmable, only the indicators are non-dimmable. The IPC backlighting (graphics and pointers) is directly controlled by the Dash Integration Module (DIM) via the IP dimmer switch, the IPC receives the dimming status via a class 2 message from the DIM. The IPC controls the Instrument Panel Integration Module (IPM) VF display dimming via circuit 1369 (YEL).
