LUGGAGE COMPARTMENT DOES NOT OPEN WITH REMOTE CONTROL

When opening is controlled by means of the remote control unit, the boot lid does not open.

The boot lid opening command is received by the Body Computer Node via the internal radio aerial; the Body Computer Node releases the boot lock and releases is slightly. With the alarm on (if fitted), when the boot button is pressed using the remote control which operates its release, the system disables the volumetric/tilt modules and disables boot entry from perimeter protection (door and bonnet entry remaining activated). When the door lock is disengaged, the boot lid opens to operate the electric handle on the bonnet. In 'independent boot' mode, boot lid opening is implemented by means of a remote control unit or dowel on the mechnical key.
