GENERAL DESCRIPTION

In addition to using the key in the rear lock, the luggage compartment can also be opened from inside the car through an electrical control.

The switch that opens the lock by an electromagnetic control is to be found on the "Check Panel" at the centre of the dashboard; the switch ideogram is illuminated when the side lights are on.

This device only works with the key either at STOP or disengaged; otherwise the boot must be opened manually.

FUNCTIONAL DESCRIPTION

The boot opening relay I52 controls the system.

The relay is supplied when the "key-operated" supply is disengaged, through the line of the power windows, protected by wander fuse G310 and through relay/switch I12.

With the ignition key disengaged or at STOP, the coil of relay switch I52, is energized by an earth signal leading from the luggage compartment opening switch located in C16.

The relay switch then sends the supply to the luggage compartment opening electromagnet M12 which triggers the lock.

With the key at "MARCI A" relay I52 is not supplied. The switch in C16 is illuminated when the side lights are on. For further details see "Illumination of controls and indicators".
