We also know that at least our source for power and source for ground is good since we have proper drivers side window and lock operation. The DDM and PDM control and integrate many functions and features of the vehicle through both hard wired outputs and messages over the PCI data bus. This power center houses plug-in Cartridge fuses which replace in-line fusible links.

Your vehicle is equipped with an electrical power distribution center located in the engine compartment near the battery. It shows the components of the circuit as simplified shapes, and the aptitude and signal connections surrounded by the devices. The PDM also receives inputs through an integral Radio Frequency (RF) Remote Keyless Entry (RKE) receiver. Underhood Fuses (Power Distribution Center) Jeep Grand Cherokee 1999-2004. 2004 Jeep Grand Cherokee Door Wiring Harness Diagram wiring diagram is a simplified gratifying pictorial representation of an electrical circuit. The DDM and PDM each utilize integrated circuitry and information carried on the Programmable Communications Interface (PCI) data bus network along with many hard wired inputs to monitor many sensor and switch inputs throughout the vehicle. Looking through the service information I also come across this- I underlined the important tidbit of information. Both the DDM ( Drivers door Module) and PDM ( Passenger Door Module) share a common power and ground feed as well. It is a peer to peer network meaning that any module on the network has the ability to communicate on it's own. It is very much like GM's Class 2 data buss. The system utilizes door modules in each door that communicate through a data buss called PCI ( Programmable Controller Interface) buss.
