These general corrective actions may solve your problem:

• Read/Write Error Actions

• Debugger-to-Target Communication Error Actions

• Debugger-to-PC Communication Error Actions

• Corrupted Installation Actions

• USB Port Communication Error Actions

• Debug Failure Actions

• Internal Error Actions

If you receive a read or write error:

1.

Did you hit Abort? This may produce read/write errors.

2.

Try the action again. It may be a one-time error.

3.

Ensure that the target is powered and at the correct voltage levels for the device. 
See the device data sheet for required device voltage levels.

4.

Ensure that the debugger-to-target connection is correct (PGC and PGD are 
connected.)

5.

For write failures, ensure that “Erase all before Program” is checked on the 
Program Memory tab of the Settings dialog.

6.

Ensure that the cables used are of the correct length.

The MPLAB ICD 3 in-circuit debugger and the target device are out-of-sync with each 
other.

1.

Select Reset and then try the action again.

2.

Ensure that the cable(s) used are the correct length.

The MPLAB ICD 3 in-circuit debugger and MPLAB IDE are out-of-sync with each other.

1.

Unplug and then plug in the debugger.

1.

Reconnect to the debugger.

2.

Try the operation again. It is possible the error was a one time glitch.

3.

The version of MPLAB IDE installed may be incorrect for the version of firmware 
loaded on the MPLAB ICD 3 in-circuit debugger. Follow the steps outlined in 
Section 7.3.4 “Corrupted Installation Actions”.

The problem is most likely caused by a incomplete or corrupted installation of MPLAB 
IDE.

1.

Uninstall all versions of MPLAB IDE from the PC.

2.

Reinstall the desired MPLAB IDE version.

3.

If the problem persists contact Microchip.
