• Internal Ground Failure: Thermal stress causes internal circuits to expand and break when hot, resulting in stalling and a temporary no-start condition until the unit completely cools down.
• Tuning Bricking: The module is highly sensitive to voltage drops or data interruption during a software write, causing it to lock up and drop completely off the network.
• Throttle Driver Failure: Voltage spikes from a sticky throttle body melt the ECU's internal H-bridge driver chip, locking the car into a permanent "Reduced Engine Power" limp mode.
