1. High speed fan control (corresponds to ECU50#); 2. Low speed fan control (corresponds to ECU68#);
The operating mode of fan after engine stops: 1. Failure of intake air temperature sensor of engine, delay 60s; 2. Failure of intake air temperature sensor of engine, delay 60s; 3. Engine coolant temperature exceeds 100.5 , delay 60s; ℃
4. Engine coolant temperature exceeds 70.5 , delay 60s. ℃
16. Position Sensor of Double Brake Pedal 16.1 Function: 制动开关传感器是将刹车信号送给 ECU,ECU 根据(原文不全) 16.2 Working principle: Inside the brake switch, there are two mutually independent switches with one normal close and the other normal open. After applying the accelerator pedal, the former normal close switch turns to be normal open, while the normal open one turns to be normal close. Both signals will be sent to ECU to be used to control other systems. Whenever the two signals disaccord, ECU will enter failure mode, the electronic throttle will not respond when applying the accelerator pedal and the engine will maintain idle speed working state. Composition: the double brake switch is installed on the bracket of the brake pedal and contains two independent switches inside. Installation requirement: the assembly is installed on the pedal and there is a thread adjusting mechanism on the switch for stroke adjustment of the switch and effective stroke adjustment of the brake switch.
