Remove the screws, then open the decorative panel. Separate the clips and take out the engine anti-theft chip. The ignition switch has five wires, usually only one is constant power. Connect the constant power wire on the ignition switch together and switch to ACC position. From ACC state, use the mechanical key to switch to NO position. Except for the constant power, ACC, and two other wires, measure the remaining three wires from the original car ignition switch.

What are the reasons why an LNG natural gas vehicle cannot accelerate?

Here are the specific reasons why an LNG natural gas vehicle cannot accelerate: 1. Insufficient fuel: The fuel in the vehicle's gas tank is severely insufficient. Check the remaining fuel level displayed on the dashboard, and if it is too low, replenish the fuel promptly. 2. Fuel quality: There is an issue with the fuel quality, such as the gas having too low a calorific value, resulting in insufficient power and torque, leading to weak acceleration. Replace the gas with one that has a higher calorific value. 3. Valve not fully open: The gas or liquid outlet valve on the gas tank is not fully opened, causing insufficient fuel supply, which results in weak acceleration. Simply fully open the valve. 4. Clogged air filter or fuel injector: Check if the air filter or fuel injector is clogged. Regularly clean and replace the air filter and fuel injector.

Will the paint chip when opening the car door and hitting the adjacent door?

Opening the car door and hitting the adjacent door generally will not cause the paint to chip. However, if excessive force is applied, some damage may occur. Specific details are as follows: 1. If paint chipping occurs: It may be due to previous impacts on the door or improper treatment of the door's primer. If the paint chipping is severe, repainting may be necessary. For minor chipping, touch-up paint can be used. If the chipping is very slight and does not affect the primer, the issue is not serious. 2. Additional information: Car painting involves applying a layer of paint to the car's surface to protect it. Automotive paint is typically a type of baked enamel. In car manufacturing plants, after the frame and body are welded, the next step is painting. Types of paint include standard paint, metallic paint, and pearl paint. The painting process involves applying putty, sanding, and spraying paint.
