Checking the signal from the switch in the tailgate/trunk lid

Open and close the trunk lid / tailgate. The status should change when the tailgate/trunk lid is opened/closed.

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.
