Description And Operation
DESCRIPTION
The power distribution system can consist of the following components:
| 1. | Refer to POWER DISTRIBUTION CENTER (PDC) . |
| 2. | Refer to BATTERY . |
| 3. | Refer to POWER INVERTER MODULE (PIM) . |
| 4. | Refer to POWER OUTLET 230 VOLT . |
| 5. | Refer to BODY CONTROL MODULE (BCM) . |
OPERATION
| Refer to COMPONENT INDEX . |
The Battery with the Intelligent Battery Sensor (IBS) is monitored by the BCM. In the event the battery voltage reaches a low or critical state, the BCM will not allow the PIM to supply voltage to the 230 volt power outlets.
| Refer to COMPONENT INDEX . |
- Receives hard wired input from sensors and switches
- Provides logic and output control of certain electrical systems
- Provides load shedding logic and control
- Acts as the central module for the Controller Area Network (CAN) bus
- Supports flashing (reprogramming) of itself as well as other Electronic Control Units (ECUs) on the CAN-bus network
- Stores vehicle configuration data (PROXI)
| Refer to COMPONENT INDEX . |
The PDC for this vehicle is designed to provide safe, reliable, centralized and convenient access to distribution of the electrical current required to operate all of the many standard and optional factory installed electrical and electronic powertrain, chassis, safety, comfort and convenience systems. At the same time, these systems were designed to provide centralized locations for conducting diagnosis of faulty circuits and for sourcing the additional current requirements of many aftermarket vehicle accessory and convenience items. The PDC connects directly to the B(+) cable.
These power distribution systems also incorporate various types of circuit control and protection features, including:
- Automatic resetting circuit breakers
- Cartridge fuses
- Blade fuses
- PCB and non-PCB Relays
| Refer to COMPONENT INDEX . |
The AC power outlet receives 12 volts from the PDC and passes it as an enable signal to the inverter module. The inverter module also receives 12 volts via the PDC and inverts this to a 230 volt AC output (220 volt for BUX models). The enable signal received from the power outlet enables the inverter to convert the received voltage and pass it to the power outlet to power external devices
| Refer to COMPONENT INDEX . |
The 230 volt AC power outlet switch receives its enable signal from the BCM. This signal is then passed to the PIM which in turn supplies power to the 230 volt AC power outlet. The PIM receives its 12 volt supply from the PDC and inverts this to a 230 volt AC output. The enable signal received from the power outlet switch enables the PIM to convert the received voltage and pass it to the power outlet to power external devices.
