323001602 - P010 CENTRAL LOCKING NOT WORKING

When the central locking is activated using the mechanical key or from the inside, via the safety knob, the central locking system does not work.
The door opening/closing command reaches the body computer node. The latter sends the signal received to the actuators which close/open the side doors, and directly controls the closing of the boot lid.
