Powertrain Control Module: Diagram Information and Instructions
Introduction
Introduction
Vehicle Identification Numbers (VIN)
VIN ranges are presented in the following manner:
->VIN 123456 indicates "up to VIN 123456"; VIN 123456 -> indicates "from VIN 123456 on".
Jaguar S-TYPE Electrical System Architecture
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 is controlled via the GECM and the RECM from SCP messages. After ignition ON, four relays are activated by either
the GECM or the RECM for as long as SCP messages remain on the SCP network. The relays will remain activated after ignition OFF, until all SCP
messages are removed. Refer to Figure 01.5. See: Diagrams/Electrical Diagrams/Diagrams By Figure Number/Fig 01.5
Engine management and transmission control are combined into a single Powertrain Control Module eliminating the need for a controller area network.
The Jaguar S-TYPE employs an SCP network for all powertrain, chassis and body systems interface / control. An ACP network is employed for audio
and communications systems interface / control.
Circuit ground connections are made at body studs located throughout the vehicle. There are no separate power and logic grounding systems.
The electrical harness incorporates hard-wired front and rear power distribution boxes and a serviceable primary junction box. All fuses and relays
(except the trailer towing accessory kit) are located in the two power distribution boxes and the primary junction box.
