A specific pad on the PCB that must be grounded or pulled up to 3.3V/5V via a resistor (typically 500 to 1000 Ohms) during startup.

Cause: You interrupted power during the checksum patch write. Fix: Use a boot pinout to force the ECU into "Rescue Mode." With the correct 4-pin JTAG pinout (TDI, TDO, TMS, TCK), you can re-flush the original bootloader. ecu design pinout patched
