IDM inputs The IDM inputs are communicated to the BCU using the serial datalink so that the BCU can perform the necessary logic operations:

The V_in for IDM digital signals are defined as follows: l Logic 1 when V_in ≥ 8V. l Logic 0 when V_in ≤ 2V.

IDM input voltages between 2 and 8 volts are indeterminate and cannot be guaranteed.
