Checking the signal from the control switch for the child lock switch

Activate and deactivate the power child locks.

The status of both doors should change at the same time as the function is engaged / disengaged.

The fault is permanent if the status does not change.

If the status changes, this indicates an intermittent fault, i. e. the fault was present previously but is not active at the moment.
