Status
Meaning
Blinking red
Errors during initializing:
• A microSDHC card is not detected.
• The microSDHC card format is not supported. This should be
reported by MPLAB X IDE or MPLAB IPE when the “send image to
too” was set.
• Initialization files are not found on the microSDHC card. Check if
Programmer-To-Go image is present in the microSDHC card.
Errors during programming:
• The power settings are not set properly. For example, if the PICkit 4
tool is supplying power, but it detects Vdd from the target. Or if the
target is supposed to be supplying power but the PICkit tool does
not detect Vdd from the target, the LED will blink red to indicate an
unexpected event.
• Memory verify errors.
• Device ID does not match.
• If the data files for programming are not found or are corrupted.

To exit from Programmer-To-Go mode, plug the MPLAB PICkit 4 unit into a PC USB port and connect to MPLAB X
IDE or MPLAB IPE. Initiate any non-PTG operation (for example, Program, Erase, etc.) and the following message
displays:
“The PICkit 4 is currently in programmer to go mode. If you continue with this operation, the PICkit 4 will exit
programmer to go mode. Would you like to continue?”
Select
Yes
