4 mile final approach and cleared to land Runway 28R in full landing configuration; message displayed a LG AIR/GND FAIL message. QRH indicated possible loss or degradation of multiple systems including braking; nose steering; and thrust rev. We were in a safe position and altitude to request an immediate right base for Runway 30. We executed a left turn for the right base while still in landing configuration-gear down flaps 45. ATC cleared us to land 30. Upon landing; all systems functioned normally and the message extinguished.Not my area of expertise but presumably a faulty air/ground sensor(s).Improved maintenance procedures could help prevent such events. Maintenance department should trouble shoot malfunctions beyond; 'could not duplicate.'
Air carrier Captain reported receiving an alert for the air/ground switch on final approach to OAK.
