Window Regulator Modules (Pt27 Only): Notes

In each door of the PT27 there is a window regulator module directly connected to each of the front door window regulator motors. The modules control window motor operation, smart glass functions and the convertible top operations (driver window module). Each module will enter sleep mode if there is no ignition switch voltage and the respective door is closed for 1 minute or longer. The module will enter wait mode if there is no ignition switch voltage for 1 minute or longer but the respective door is open. After being in wait mode for 12 hours, then with door open, the module will go to sleep mode. At this time the module will wake up only if the ignition is turned on. Under normal circumstances the module will wake up if it receives a door ajar switch sense, a window drop switch sense or an ignition switch voltage. When software changes are necessary, the modules can be flashed by using the DRBIII. Each module is capable of setting trouble codes to aid in the diagnosis when a malfunction occurs. When a module must be replaced it is necessary to replace the entire regulator assembly because of possible damage to the hall effect sensor in the module.
