The ME711 requires constant voltage on (Terminal 30). Without these, the ECU is dead. Ground integrity on pins 43, 44, 45, and 121 is critical. A common failure is a corroded engine-to-chassis ground strap, causing erratic sensor readings (especially TPS and MAP).
The processor (Infineon C167) will now be in Bootmode, allowing you to use tools like Galletto or any standard 167-flasher to rewrite the memory. Step-by-Step Bench Setup Checklist
The ME7.1.1 is part of the Bosch Motronic ME7 family, which pioneered electronic throttle control (Drive-by-Wire) and integrated torque-based management. Unlike older Bosch systems, this ECU acts as the central brain managing: (Multi-port) Electronic Ignition Drive-by-Wire Throttle Variable Valve Timing Emissions Equipment

The ME7.1.1 relies on an AMD or STMicroelectronics flash chip. To initiate Bootmode:
If your OBD-II scanner says "No communication" but the ECU has power (pin 80), check the CAN bus. Resistance between pin 15 (CAN Low) and pin 16 (CAN High) should be approximately (due to two 120-ohm terminating resistors in the cluster and ABS module). Open circuit (>100 ohms) means a broken wire.
