mclr vpp low

Hi. I have problem with MPLAB ICD 2, Cannot Pass Test.
It passes:
Target Vdd,
MCLR Vdd,
MCLR Vpp,
but don't pass:
Module Vpp - Low
MCLR Gnd - High????
What mean Module Vpp(what is difference between it and MCLR Vpp) and Module GND.
If I manualy connect RC2 to GND, on MCLR appear 0.068V(but icd says: MCLR Gnd - High?!?!?!?!?!)

Please help.

Thanks.

are you using the commercial icd2?



if some didn't pass, then i think you need to connect it correctly.

I don't know about your ICD. I'm using the one from Microchip.

But from your description, it seems like a connection problem. Verify your connection again.
