BCU 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 BCU processes signals received from the following components:
- Door latch switches.
- Driver's door key lock/ unlock switches.
- Bonnet activated security system.
- Volumetric sensors.
- Central Door Locking (CDL) switches.
- Remote transmitter (via receiver unit).
- Inertia fuel cut-off switch.
- Ignition switch.
- Fuel flap release switch.
The input voltages (VIN) for BCU digital signals are defined as follows:
- Logic 1 when VIN >= 6V.
- Logic 0 when VIN <= 2V.
BCU input voltages between 2 and 6 volts are indeterminate and cannot be guaranteed.
Analogue input voltages are measured as a ratio with respect to battery voltage.
