Hi Guys!!! Newbie here, just want to ask you guys what do you think this problem maybe from my GTR. My Hicas light will turn on suddenly when I pass thru some kind of rough road .. And I hear this clicking sound in the rear trunk bottom left side area, sometimes the click is simultaneous w/ the hicas light turning on, don't know if coincidence though. The clicking sound sounds like a relay flickering. Any of you mates experienced this?
