Default Re: How to stop roof alarm

Think of how the system works logically. When you pull the top down to meet the windshield frame, the "top open" switch above the passenger's head opens. This tells the top controller that you have latched the top to the frame (or are in the process of doing so). It is beeping because there is a sensor somewhere indicating that it is not appropriate to latch the top, that is, in the mind of the controller, the cycle did not complete.

What gets me when this happens, is that the sensor apparently DID indicate that the rear bow latch is latched, because the sensor told the pump to quit running. Since that is the last sensor needed to complete the cycle, how can there be anything wrong here? If the trunk latch sensor was at fault, the top pump would never have even started up. If the electric trunk lock sensor was at fault, the top pump would have never started up.

It stands to reason that if ANY sensor acted up, the controller would become confused and stop running, or so it seems to me. I wonder about the travel sensor on the rear bow latch. It seems to me that lubricating the rear bow latch (underside of tonnaue cover) has resolved this at least once. It's almost as if the latch sensor indicates '"latched, stop the pump!", then, as soon as the pump stops, the latch becomes "unsettled" and tells the controller, 'The bow is not secure after all."

My first suspect is the rear bow latch. We KNOW something is telling the controller that something is not right. And we know that it does not do it in the "lowered" position. My first guess is the rear bow latch. "Shamrock" once lubricated that latch and cleared his problem, which I think was "light flashes and it beeps when the top is up". If it was not him, it was SOMEONE on here...................
