PRCM Displays After Input Subset Selection
Complete Input SelectionCharacters "9" through "12" represent the entire input selection. Characters "9" and "10" remains identical to step 3. Characters "9" through "12" for the input selection are flashing. The flashing indicates that the operator is able to select an input code within the subset. The subset was chosen in step 3.The "UP" and "DOWN" buttons scroll through the table of inputs. An input code of "2011" is selected for the engine oil pressure warning. The inputs can be special functions. The inputs can be PRCM discrete inputs. The inputs can be data from the ECM. Refer to Testing And Adjusting, "Display Codes" tables 1, 2, and 3. Refer to these tables for a listing of terms of the input codes.After selecting an input, press the "LEFT" and "RIGHT" button. This will allow the operator to proceed to step 5.

PRCM Displays After The Entire Input Selection
Select All State.Characters "1" through "12" should now be flashing. This state allows the operator to select all the changes that will be programmed. This state also allows the operator to disregard the previous changes.The upper display will flash until the "SELECT" button is pushed in order to accept previous selections. The upper display will flash until the "LEFT" and "RIGHT" button is pushed in order to reject the previous selections. If the "SELECT" button is pushed, the display stops flashing for two seconds in order to show that the selections have been programmed successfully into the PRCM. The program returns to Step 1 in order to allow the user to continue programming the remaining outputs and inputs.If the "LEFT" and "RIGHT" button is pushed, the program returns immediately to Step 1, but the previous selections are NOT programmed into the PRCM.

PRCM Displays After Programming
Press the "ENTER" button in order to exit the programming mode.The following illustration represents an inactive input and output. When the ECM detects a low engine oil pressure condition that is within a specific alarm range the data for this condition is sent to the PRCM via the CAT data link. The PRCM will display characters "5" through "8" as being active. The "K1" symbol will be shown on the lower display to show that this relay is activated. The normally open contacts will close. The device that is connected to the output will activate.

PRCM Display With Active Input (Low Oil Pressure Warning From ECM)In another example, the PRCM input and output has been programmed to activate alarm "1" whenever switch input 1 is inactive. The top LED display will be activated. Characters "5" and "6" show that the output is active. Characters "7" and "8" show that the input is inactive. The colon between characters "6" and "7" indicates that the output state is inverted from the input state.
