Zusammenfassung:	PURPOSE:To facilitate the discovery of a malfunction position by indicating an emergency brake due to a malfunction of a lead wiring power source, of an original air reserving pressure and of lead wirings in accordance with the causes. CONSTITUTION:When an emergency brake is operated, an operation detection timer relay 13 of an operation detector 11 is excited. Since a confirmation relay 16 is operated when the brake is operated due to the operation of an ATC, lead wiring indicator lamp 19 remains deenergized. Since a trip detection relay 14 is deenergized when the lamp is energized due to the trip of a lead wiring power source 2, a trip indicator lamp 17 is energized. When the lamp is energized due to the original air reserving pressure, a pressure detection relay 15 is energized, and a pressure indicator lamp 18 is energized. Since the relay 16 remains deenergized when the brake is applied due to the malfunctions of the lead wirings 1a, 1b, the indicator lamp 19 is energized.
