The invention discloses an automobile ECU casing sealing test method and instrument. The test instrument comprises a pedestal, a test pot and a seal cover, the test pot is fixedly connected to the upper surface of the pedestal, the seal cover is movably connected to the top of the test pot, the lower surface of the seal cover is provided with a chute, the inner wall of the chute is fixedly connected with a sealing rubber pad, the sealing rubber pad is overlapped with the top of the test pot, the surface of the test pot is fixedly connected with a fixed block, the fixed block is movably connected with a movable arm via a pin, one end of the movable arm is movably connected with a roller via a rotating shaft, and the surface of the roller is overlapped with the upper surface of the seal cover. Movement of first and second movable blocks reflects sealing performance of an automobile ECU casing, sealing test via precise weighing is avoided, and the problem that a sealing test result is influenced in a common working environment of the present sealing test instrument and operations becomes inconvenient is solved.
