9.4 ICD Test Interface Module

To use this module to verify that the debugger is functioning properly:

  1. Disconnect the debugger from the target and the computer.
  2. Connect the ICD Test Interface module (AC164113) to the debugger using the modular cable.
    Figure 9-8. MPLAB ICD 4 Connection to Test Interface Module
  3. Reconnect the debugger to the computer.
  4. Power the MPLAB ICD 4 through the USB cable to the computer.
  5. Launch MPLAB X IDE. Ensure that all existing projects are closed.
  6. Select Debug > Run Debugger/Programmer Self Test. Then select the specific “ICD 4” you want to test and click OK.
  7. Ensure the ICD Test Interface module and cable are connected. Click Yes to continue.
  8. View the self-test results in the debugger’s Output window. If the test runs successfully, you’ll see the following: 
    Test interface PGC clock line write succeeded. 
Test interface PGD data line write succeeded. 
Test interface PGC clock line read succeeded. 
Test interface PGD data line read succeeded. 
Test interface LVP control line test succeeded. 
Test interface MCLR level test succeeded. 
ICD4 is functioning properly. If you are still having problems with your 
target circuit please check the Target Board Considerations section 
of the online Help.
  9. After the debugger passes the self test, disconnect the ICD Test Interface module from the debugger.

If any test failed, verify all connections. If failures still occur, please enter a ticket on support.microchip.com. Copy and paste the content of the Output window into the problem description.
