1, the driver can not pull out of the AL4 automatic transmission from the P gear can not pull out of the driving lever from the P gear (stop gear), when it is not up to other files (N: D: running gear; R: reverse), the car does not move, the driver will be very annoyed. Of course, driving a joystick with a hard hand is of no use. An ingenious method of pulling the joystick: A, the short connection brake light switch input and output line end; B, plugged out the electromagnet with a large Jack in the lock stop and quickly pulling out the drill rod; C, dismantling the central sundries box and pulling the armature of the lock driver directly. Core, pull the gearshift lever to "N". Of course, there is a premise to eliminate this fault, that is, the brake lights are not effective after stepping on the brake pedal. If the "SPT" and "*" lights flashing on the dashboard may be the damage of the automatic transmission computer or the protection of the starting relay, it is not possible to use the above method to pull the transmission lever. 2. The gas resistance will also occur in the oil supply system of the electric spray car. Besides the design reasons (such as the Daewoo car), the oil tank and the oil pipe near the high temperature area, the gas resistance is easy to happen, and the traditional cooling method of cold water and cold cloth is needed to eliminate. Other electronic fuel injection vehicles will also produce air resistance, such as Fukang electric vehicle suddenly extinguished in the road, can not start again. At this time, we should open the electric door, start several times, use the oil basin to catch the disassembled car filter outlet oil, until the bubble gas is discharged, tighten the oil pipe. At the same time, it will tell you, don't press the white button in the tank, and fill the tank with oil, so that the gas tank is not discharged. This kind of fault is most likely to occur in a full tank taxi. 3. The way to prevent flooding is Fukang car driving in rainstorm, prone to flooding. The reason is that the suction port is located in the front and bottom of the water tank mask. The splashing mud is easy to suck the cylinder from the suction port through the air filter, resulting in flooding the cylinder and damaging the cylinder block. At the same time, due to the structural characteristics of Fukang car in the northern part of the dust storm, the dust is also easy to enter the air filter from the suction port and cause blockage and flameout. Emergency method: in sandstorm weather, dust removal from air filter element should be cleaned frequently, and the suction port can also be turned to side effectively. In heavy rain days, we should control the speed and choose the road surface and not flood the pool. If the rainstorm is persistent, simply remove the suction pipe from the end of the air filter and install it after the fine weather. It can effectively avoid the accident of flooding and tamping.
