I am using PIC18F67K40 and PICKIT3 with MPLAB 8.92V for programming. But I am getting error:
Failed to get device ID
I have attached schematic snap of MCLR circuitry. I am able to program other board using the same kit, so I am not suspecting malfunctioning of kit.
So far I have tried below:
-
Using external supply for target
-
Setting different voltage in settings of MPLAB
Update: I was able to program the chip using @Mike suggestion, Now i am getting Following Error/Warning for another chip of same model
MPLAB X has detected that the device’s low voltage configuration bit is set to OFF but the tool is set to low voltage programming and cannot program the device. To correct this:
- Change the tool’s programming option to use High Voltage programming.
- Change the device’s configuration bit to use low voltage (LVP=ON). Program the device using high voltage to reprogram the device’s
configuration bit.- Change the tool’s programming option back to Low Voltage programming for subsequent programming of the device.

The PIC18F67k40 is not supported by MPLAB 8.92 (it's pretty old)
You had to update your IDE to MPLABX (v5.25)
In your source code there should be a configuration section:
