Abstract: Carry out the rain test of the whole vehicle in the trial production stage, investigate the typical water leakage problems that occurred in the door waterproof membrane, door guard plate, wiring harness, etc., and formulate corresponding improvement measures through the analysis of the failure cause, and finally solve the problem of water leakage in rain test. Accumulated experience for the design of subsequent models.
