Convertible Top: Testing and Inspection

Any diagnosis of the power top system should begin with the use of a scan tool and the proper Diagnostic Procedures Information. The scan tool can provide confirmation that the Programmable Communications Interface (PCI) data bus is functional, that all of the electronic modules are sending and receiving the proper messages on the PCI data bus, and that the power top motor is being sent the proper hard wired output by the driver window regulator module.
