Jaguar S-TYPE Electrical System Architecture
Power Supplies
The Jaguar S-TYPE electrical system is a supply-side switched system. The ignition switch directly carries much of the ignition switched power supply
load. Power supply is provided via three methods: direct battery power supply, ignition switched power supply, and "Switched System Power Supply".
The "Switched System Power Supply" circuit is controlled via the GECM (General Electronic Control Module) and the RECM (Rear Electronic Control
Module). Refer to Figure 01.6 for circuit activation details. See: Diagrams/Electrical Diagrams/Diagrams By Figure Number/Fig 01.6
Fuse Boxes
The electrical harness incorporates two hard-wired power distribution fuse boxes: the Front Power Distribution Fuse Box located in the engine
compartment and the Rear Power Distribution Fuse Box located in the trunk. A serviceable Primary Junction Fuse Box is located in the front right-hand
foot well. All fuses and relays (except the trailer towing accessory kit) are located in the two fuse boxes.
Vehicle Networks
The New Jaguar S-TYPE employs three different networks: a CAN (Controller Area Network) for high-speed power train communications, an SCP
(Standard Corporate Protocol) network for slower speed body systems communications, and a D2B (Optical) Network for very high-speed "real-time"
audio data transfer. The D2B Network is a fiber optic network with a gateway to the remaining vehicle networks via the Audio Unit. Technician access
to the three networks and the Serial Data Link is via the Data Link Connector.
Ground Studs
Circuit ground connections are made at body studs located throughout the vehicle. There are no separate power and logic grounding systems; however,
there are a certain number of components that use unique ground points.
