PRPC Operation:
Turning the vehicle ignition ON will wake up and initialize the PRPC501 module. Outputs are
controlled based on the module’s configuration created using the Intermotive PRPC Programming
Utility program.
When the key is turned OFF, the PRPC501 module will go into a low power sleep mode . This may
take up to TEN minutes, and the LED’s on the module will go out once in sleep mode. Other vehicle
activity such as opening doors, inserting key in the ignition, etc. may delay sleep mode.

Inputs:
To enter Input diagnostic mode, momentarily press the red test button on the module (look
for “TEST” on the printed circuit board)
TWO
times with the ignition on. The on-board yellow
status LED will blink twice every second in this diagnostic mode. The on-board red fuse LED’s
will light when a corresponding Input is active:

Scrolling LED’s:
This may indicate one of the following errors:
•
LED’s scrolling sequentially one at a time indicates that an invalid or incomplete VIN was
captured.
•
LED’s scrolling from the middle outward indicates a configuration error. This can be the result
of configuring the PRPC for one chassis, but installing it in a different chassis.
PCB Temperature Load Shedding:
The PRPC monitors on-board temperature in three different locations. If any one of the readings
exceeds a predetermined temperature threshold the module will shed one relay load every 2
minutes to regulate heat. The outputs where the temperature readings are highest will be shut off
first. If at any time a temperature reading is 5C above the predetermined temperature threshold
the module will shed one relay load every second until all relays are off.
If this sequence is triggered the module will beep 5 times in about 30 seconds at high pitch before
shedding any output.
