Which (e.g., 24C16, 95320, 93C46) are you working on right now?
: While iProg supplies bus power over USB, in-circuit reading can back-feed power to the vehicle module, dropping the USB voltage and causing read errors. A stable, isolated power injector keeps data clean. Technical Precautions for Portable Operation
Portable programming requires strict adherence to voltage levels to prevent hardware damage. iProg adapters usually auto-detect VCC, but manual verification is recommended.
If reading in-circuit using a portable clip fails, the onboard microcontroller is likely interfering. You must desolder the chip and place it directly onto the EEPROM adapter board socket for a stable read.
