and steering, etc.): Battery power. The height of the coolant level of the drive motor. Whether the tire pressure is qualified, whether the type and pattern are applicable, and whether it exceeds the wear limit. Whether the battery, the drive motor, the surrounding area of the transmission and the vehicle bottom are leaking oil or water. Note down the location of the possible leak and wipe the nearby area clean so that the extent of the leak can be easily checked after the test is completed. 1.1.1.1.5.1 When turning off the ignition device, check Apply parking brake. Whether the shift lever is in the neutral position. Whether all meter pointers point to zero.
1.1.1.1.5.2 When turning on the ignition switch, confirm Whether the ignition switch indicator light is on. Display parking brake indicator and liquid level indicator. 1.1.1.1.5.3 Road or roller test bench test inspection Warning: During the road test, the braking system should be checked when the car is running slowly. If the brakes are misaligned or have other problems, please find out the problem and adjust it. Do not use the road until the problem is solved. Parking brake is easy to control, and the release of parking brake is quick and complete. The output power of the drive motor is normal, the output is normal, and the acceleration is stable.
The accelerator pedal can be controlled freely, and the idling speed of the drive motor returns to normal. The steering operation includes whether the power steering is normal, smooth, and precise, the steering wheel is too heavy or too light, and the direction swing. The steering wheel automatically returns to position after turning. Odometer, battery warning light, coolant temperature pointer, tachometer pointer reading is correct or working normally. The switch and control system work normally, and the warning light (indicator light) works normally and automatically goes out after the steering wheel returns. The heating and ventilation system is working properly.
The braking system is working properly. 。 1.1.1.1.5.4 Brake test Warning: When detecting the brake, avoid breathing in the smoke released by the hot brake. Smoke may contain asbestos fumes which are harmful to humans. Avoid detecting brakes on roads with lots of cars, as this may cause inconvenience or danger to others. Warning: Brake tests including heavy braking should not be performed on new brake shoes/brake discs or friction linings/brake discs, unless the components have run-in due to the new brake friction components Before running in completely, the efficiency cannot be fully utilized.
Step on the brake pedal lightly and hard, and test the braking at various speeds under normal operating conditions in each gear. Let the vehicle slide, pay attention to the tendency of the vehicle to run off, or the phenomenon of brake stickiness. After the vehicle stops (non-emergency braking stop), carefully check the brake temperature. If the brake disc is very hot, or much hotter than other brake discs, it means there is brake stickiness. 15
