BCU inputs

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.
