Which chip are you using? What is the supply voltage? ICD2 has quite a lot of restrictions as a programmer and a debugger. For quite some low pin-count device (eg. PIC12F629/675, 16F630/676, 16F627A/628A/648A), you will even need an header for debugging. Also please check the connection. The biggest problem I have with ICD2 is actually the connection. ICD2 is very picky in this aspect.

Subject: [PIC] ICD2 Hi, I'm just starting with pic-microcontrollers, and have ordered the icd2 from microchip. But it isn't working, I always get this error after programming the device ( I have selected the icd2 as debugger): ICD0083: Target not in debug mode, unable to perform operation Can anyone help me, what do I wrong?
