IDM inputs
WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2004 Land Rover Discovery, 2003 Land Rover Discovery, 2002 Land Rover Discovery, 2001 Land Rover Discovery, and 2000 Land Rover Discovery. However, it is still accessible from the selected car via links, so may be relevant.
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.
