上次我换Infiniti 车门把电池断了几天，装好了车打不着火，说是ECU memory sum lost. 在网上找了一大通才找到昨reset ECU.
chat GPT这样劝你：
Disconnecting a car battery for several days is generally safe, but there are some potential effects to consider:
1. Loss of ECU Memory – Many modern cars have an Engine Control Unit (ECU) that learns driving habits over time. Disconnecting the battery may reset these adaptations, leading to temporary rough idling or shifts.
2. Loss of Radio & Infotainment Settings – Your radio presets, clock, and other infotainment settings may reset. Some vehicles may require a security code to reactivate the radio.
3. Alarm & Key Fob Issues – Some factory or aftermarket alarm systems might need to be reprogrammed after reconnecting the battery.
4. Throttle & Transmission Adaptation Reset – Certain cars, especially those with electronic throttle bodies, may need a relearn procedure for smooth operation.
5. Power Window & Sunroof Reset – Automatic window and sunroof functions may stop working until they are reinitialized.
6. Battery Drain on Reconnection – When reconnecting, the car’s electrical system may experience a temporary high current draw as various modules power up.
If leaving the battery disconnected for an extended period, consider using a battery maintainer or disconnecting the negative terminal only to minimize system resets. If you’re storing a vehicle, ensure it is in a safe, dry place to avoid corrosion or rodent damage to wiring.
