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 VIN for IDM digital signals are defined as follows:
- Logic 1 when VIN >= 8V.
- Logic 0 when VIN <= 2V.
IDM input voltages between 2 and 8 volts are indeterminate and cannot be guaranteed.
