Toyota chr has no power, and it sounds like a drip alarm.

1. The battery voltage is too low and the power is insufficient. The battery is low, which makes the car's function unusable, and then it will keep ringing.

The ignition system is out of order. Problems with the ignition system will cause the engine to fail to start, and the key door will always be in the starting state. At this time, the starting relay will make a sound when it is repeatedly pulled in.

3. Motor startup and motor-related circuits are out of order. The car keeps making noise because the motor is out of control.

4. Excessive carbon deposition in the intake pipe, throttle valve or idle motor causes the engine mixture to fail to meet the required air-fuel ratio, resulting in abnormal sound.
