For those people who might visit this thread I will post the solution to using the HLVD module as I was able to resolve with some offline support from Darrel Taylor.

First, you need to make sure you have setup a DT_INTS-18 interrupt for the HLVD module by inclusion of this code:
Code:
ASM
INT_LIST  macro    ; IntSource,         Label,  Type, ResetFlag?
        ;INT_Handler   USB_Handler
        INT_Handler   HLVD_INT,        _LowVolt, PBP,  yes
    endm
    INT_CREATE                ; Creates the interrupt processor
ENDASM
Then you need to insert this in your code ahead of the main loop to setup the use of the HLVD module.

Code:
       
 ' Set registers for using HLVD feature
          ' Step 1-Disable the module by clearing HLVDCON.4
        		HLVDCON.4 = 0 	' Implement Step 1           
          ' Step2 HLVD3:HLVDL0=1101 'Set the trip point at Vdd=4.33 vdc
          ' Step3 HLVDCON.7=0 'Set VDIRMAG=0 to detect low voltage transition
          ' Step4 HLVDCON.4=1 'Enable the HLVD module
              	HLVDCON = %00011101   'Implements Steps 2-4
          ' Clear the HLVDIF interrupt flag (PIR2<2>)
 		        PIR2.2 = 0 
          ' Enable the HLVD interrupt
@    INT_ENABLE   HLVD_INT ; enable HLVD interrupt
Then you need to create an interrupt service routine (ISR) nead the end of your code as follows:
Code:
LowVolt:
   ' Blink LED_RED 5X to indicate Low Battery voltage detected
        For i = 0 to 4
           HIGH LED_RED
           Pause 500
           LOW LED_RED
           PAUSE 500
        Next
@ INT_DISABLE HLVD_INT      ; This statement very important, else code will lockup on exit
                                            ; from the ISR to main program. 
        ' Resume Main Program
@ INT_RETURN
'------------------{ End of Interrupt Handlers }-------------------------
Hope this might help someone!
