Detection 1. Detecting power: The junction box is equipped with relays and insurance for each heater. String. 2. Detect the heater: Status display of the indicator after the fuel heater switch 1) Show blue is \\"normal \\\" status. 2) Show red is the \\"fault \\\" state, indicating that the heater or cable is faulty. 3. Detecting a temperature sensor: During use (non-automatic appearance), if the indicator of the display displays the phenomenon of red / blue (or red), it means that the temperature sensor corresponding to the flash indicator failed. Troubleshoot according to the test results, it can determine the fault location and fault type, mainly including the following categories: 1. Power failure 1) Insurance: If insurance is blown, insurance is not blindly replaced, and larger capacity is not replaced.
The starter failure and excludes the beginning of the vehicle will not rotate. 1. Check the battery and power cord by speaker. If the speaker does not respond, it should check if the battery rod column is loose, rust, check if the battery is powered; 2. The battery and power cord are normal, the battery is good; 3. Two initiators on the launcher, such as the starter, Indicates that the start-conversion section is faulty; if the starter is not rotated, the inside of the starter should be further decomposed; The relay contact should be checked whether the relay contact is a circuit breaker, whether it is damaged, and the circuit, etc. The starter rotates weaknesses 1. When the starter turns to the weak point, turn on the big light or press the speaker, the headlights are bright, the speaker is loud, indicating that the battery and the line are very good: 2. Such as light light
Brake system failure and exclude braking failure, continuously decline on the brake pedal, the pedal will not rise, but there is no resistance, first check if the master cylinder is missing, then check the master cylinder and execute the pump, no leakage, if the leak should be replaced; Then check the brake tube and joints without oil, if there is oil, it should be repaired or replaced; if there is no oil to check, each mechanical connection is not detached. If the above situation is good, you should decompose the inspection status of the master cylinder KitBow and the piston. If necessary, you need to fix or replace it. Brake 1. When the brake pedal is pressed, the position is very low, the pedal is gradually increased, but it is very weak, the braking effect is not good. This indicates that there is air in the brake system, excluding the outside; 2. When the pin is braked, the pedal position is gradually increased when the pedal is braked, and the braking effect is better. This indicates that the pedal free trip is too large, the friction plate and the brake disc gap are too large or friction.
It is not damaged before and after the traction ring, the inspection is the solid ring, and the lift ring is not damaged.
Overview This section mainly introduces the important role of normal use, car safety and reliability. According to the normal maintenance cycle, the correct maintenance method is very important to the car. Otherwise, in addition to regular maintenance, the life and reliability of the car will be greatly reduced, and the safety and reliability of the car depends on irregularity. maintain. All frequent and irregular maintenance of external environments when driving
