![]() ![]() At least one parameter should be incorrect. Use the scan tool to monitor each one of the folding top position sensors and switches and compare the parameters to the matrix. Typically, if no wiring concern is present, then a DTC will not be set.Īt this point, operate the folding top to the point where it stops moving. In most cases, this condition is the result of a sensor or switch that is simply not transitioning its status. A common condition is when the folding top will stop partway through its opening or closing cycle with no DTCs set. A folding top must always complete one phase before it continues to the next phase. With all folding top systems, the top opening or top closing cycle is broken down into a series of small steps, called phases. ![]() The matrix lists all the various switches and sensors in the folding top system, including what each one should be reading based on where the top is at in its cycle. The matrix for each vehicle may be located in the Description and Operation section or it may be located in a separate bulletin/PIC. If no DTCs are set, follow the applicable folding top sensor matrix in the Service Information. Follow the appropriate Service Information for any DTCs before making any other repairs to the folding top. 2)Īlso check for any DTCs that may have set.

The next step is to check for any folding top-related messages in the Driver Information Center of the vehicle during operation. In many cases, the rear compartment will open and close correctly all by itself, but it will not operate at all when the folding top is cycled. For example, the decklid on the Cadillac XLR opens as part of the normal folding top opening cycle. If the top operates in one direction or some functions of the top work properly, it does not necessarily mean that the top will operate correctly in the opposite direction. ![]() The Service Information and a scan tool can provide valuable help in order to get to a correct diagnosis and repair.īegin diagnosis by operating the folding top to determine what works, and where does the top stop moving during its cycle. 1), it’s important to understand what is happening with the power top as well as how the top is supposed to operate.
