Description And Operation: Description
Power Distribution Center (PDC) (Rear)
The PDC is in the right rear of the vehicle and consists of three sections, one for relays and fuses (1), one for relays only (2) and a smaller one for relays and fuses (3) present only if the vehicle is provided with a tow haul. The three sections are positioned in a single support to which they are press-fitted.

Pre-fuse
The purpose of this pre-fuse assembly is to cut off the power supply to the following loads:
- Engine fan power supply
- Starter motor solenoid power supply
- Electronic Power Steering (EPS) power supply
- PDC (Front) power supply
The front of the vehicle can consist of a few different power supply arrays, depending on the model:
Base
- Relay and fuse box
- PDC (Front)

- Junction Box
POWER INVERTER MODULE
An optional inverter module (2) may be installed on the vehicle to transform direct current into alternating current (DC/AC inverter). The inverter is a device that uses diodes and transistors to create alternating current, the inverter operate at 110 volts. The inverter is a 150 watt device that can supply approximately 300 watts for a maximum time of approximately two seconds so as to compensate for current overload which could occur when a device is plugged in. To prevent blowing the fuse, the inverter automatically switches off if the device needs more power than required. The module inverts the 12 volts of direct current into the correct alternating current value. The BCM will activate the inverter by sending a positive command when the key is on and when the engine is running and there are no alternator errors. The inverter module detects the presence of this positive command when an object is plugged into the switch (1) and activates power to the A/C socket.
