ICD3 not detect the device ID

Dear All,
Please help to resolve the programming issue of PIC18F97J60 using ICD3, ICD2 is working with same controller but ICD3 not detect the device ID.
Please find the attached connection details.
 
Regards,
Rani

    "...not detect the device ID" usually indicates either a broken communication line (cable) or - sometimes - a broken ICD3.
    Start with the self-test to make sure the ICD3 and the cable are operational.

    PEBKAC / EBKAC / POBCAK / PICNIC (eventually see en.wikipedia.org)

    do you have any components on PGC or PGD??  What is the pull up on MCLR, or what other components are on MCLR?

    Hello,
    ICD3 detects the other cards controller with same connection, and also not having any other component's on PGC and PGD.
    This error only appeared with one of the card and which works with ICD2.
     
    We did some experience on that, instead of 5V connection we make the 3.3V connection on programmer connector as shown in previous communication attached image.
     
    Supply power 3.3V from ICD3 instead of external 5V and it works with this setting.
     
    Thank you.
    Rani.

    Different communication problems can be a result of to long PGD track, also track connected to PGD and going somewhere, like antenna. Or a little bigger capacity on this line.
    Very good idea is pulling down PGD pin using resistor 4k7 or less (but not smaller than 1k) directly at the end of programmer cable.

    Or a 100R series resistor on the PGD line at the PIC end, to reduce ringing and crosstalk to the PGC signal.

    This forum is mis-configured so it only works correctly if you access it via https protocol.
    The Microchip website links to it using http protocol. Will they ever catch on?

    Hi,
    Are you really using 5V power supply on the PIC18F97J60 ????? (from your ICSP picture in message #1).
    If so the PIC is probably dead by now or partially dead....because it needs absolute MAX 3.6V (nominal is 3.3V)
    Please make sure to put a 10K to 50K pull-up resistor on MCLR.
    Failing to do that will make you waste lots of hours in the future...
     
    I strongly recommend you exchange the PIC18F97J60 because it may me partially damaged...
     
    Regards

    Thank you all for suggestion.
    There is error in layout, this 5V is not get connected to controller VDD 3.3V and hence PIC18F is safe.
    Now we modified the layout for 3.3V at connector, we test it by cutting the 5V track and connecting 3.3V at ICD connector and it working ok.
     
    Thank you for guidance and support.
     
    Regards,
    Rani.

    That will do it.
    Pin 2 of the connector MUST have the same voltage as the PIC's power supply because the programmer uses that to set the input and output voltage thresholds.
