Hi,
trying to read PCR2.1 by VCP (VAG CAN PRO genuine) in boot, but not working. Actually I need only MCU ID.
Getting communication on bench, can read flash file.
In ECU flasher menu selecting PCR2.1 EEP.
Switching of power supply, and connecting wires and resistors by chematics (strange that one resistor marked in red and looks like "+" sign there..hhhmm)
trying to read by "Boot MCU".
When trying to read always getting answer NoBootACKFrm, the same answer when reading with switched off power supply or disconnected OBD plug.
ECU on bench using 0.4A and with resistors connected 0.2A (looks like it should be in boot mode), when trying to read "BootMCU" can sea blinking for split second CAN-H and CAN-L LED's, looks like there was attempt to read, but amperage staying the same 0.2A.
p.s. on Win XP diagnostics works, but not recognising ECU on bench. Win7 x64 reads ECU flash on bench.
Any ideas?
Kind regards
