* * 在以下情况下智能功能将不起作用，万一智能功能根本不起作用时一定要进行检查。 位于驾驶员侧仪表板下的智能取消开关打开 智能钥匙插进插槽 智能钥匙没电（即使按钮智能钥匙的按钮，指示灯也不闪烁） The smart function will not operate under the conditions listed below. Make sure to check them in case the smart functions do not operate at all. The smart cancel switch provided below the driver’s side instrument panel is turned ON. The smart key is inserted in the card slot. There is no battery in the smart key (the indicator light dose not flash even if the buttons on the smart key are depressed). * * 再生制动力作用在前轮(驱动轮) Regenerative brake is used for front wheels (drive wheels) * 制动防滑控制ECU由16-位变为32-位 Skid control ECU is changed from 16-bit to 32-bit * 蓄电池充电量越多,阻力越大. * ECB: 电子控制制动 制动灯的运作与 ’03 PRIUS相同 * 主缸切断电磁阀关闭.主缸压力不传递到轮缸.主缸压力只由制动踏板产生. 供压电磁阀和减压电磁阀线性地控制轮缸压力. Master cylinder cut solenoid valve is closed. Master cylinder pressure is not transmitted to wheel cylinder. Master cylinder pressure is used only for detection of the driver’s demand Pressure intensifier valves and pressure reduction valves are operated linearly to control wheel cylinder pressure sensitively * 假如在制动失效时双位电磁阀打开,制动液流至制动模拟器,使得分泵压力上升就会延时. 制动系统关闭=双位电磁阀”关闭” If two-position solenoid valve is open during brake failure, the rise of front left wheel cylinder pressure is delayed by the flow of brake fluid to brake simulator Brake system OFF = Two-position solenoid valve “closed” * * C1247(47):行程传感器故障 * * 两条传感器电路（主和副）。 在传感器里主和副电路都是同样的特性。 There are two sensor circuits (main and sub) Main and sub circuits in the sensor are the same characteristic * * 两条传感器电路（主和副）。 在传感器里主和副电路都是同样的特性。 There are two sensor circuits (main and sub) Main and sub circuits in the sensor are the same characteristic * 驻车开关是瞬间型的 * 闪烁 (快) ? 0.13秒. ON - 0.13秒. OFF 闪烁 (慢) ? 0.5秒. ON – 1.5秒. OFF * * 车速状况:发射控制ECU接收车辆”停车”或”行驶”的状态 [机密] 3km/h (1.9 mph) 或低于= 停车 超过3km/h (1.9 mph) = 行驶 Vehicle Speed Condition: transmission control ECU receives vehicle “stopped” or “driving” condition [Confidential] 3km/h (1.9 m
