i measured b6,b7 signals with oscilloscope. b7 is at 0v, b6 is at 5v.
so icdsignals is bad -> software says:
If there are no signals on either of the lines the ICD unit is bad.Call 262-522-6500 or Email [email protected] to repair/replace the unit.
If the signals look noisy/distorted check the cable/connection from icd to the target.
If the signals look good check MLCR and vdd lines for noise.

im at turkey, i hope repair it with your supports.
im waiting your response. thanks.
