Daily maintenance points chassis bottom protection against erosion

Crushed sand more urban roads, chassis maintenance to seek good method, many
owners to buy a new car, with the car sticker, sealing glaze, floor glue, etc.,
but very few people will consider to take some protective measures for car
chassis. The recent guangzhou road engineering, potholes in the road condition
of automobile chassis is a great test. Local 4 s shop repair shop a week chef
here remind each owner: "rotten rotten bottom first", the protection of the
chassis but very important oh.
Large, small sand damage in the used-car market, owner judge colour of the
vehicle, the chassis is one of the most intuitive judgment standard. So what is
the damaged car chassis?
Week the teacher said, generally in the summer, the sun baking, rain hit on the
ground and the humidity of the atmosphere, salt etc will be eroded car, vehicle
chassis aging. Now most of the roads are built in guangzhou, gravel on the road
is more, the impact of sand stone, also can make the chassis antirust paint was
damaged, so that the metal exposed on the surface of the chassis, oxidation and
direct contact with water rust quickly.
Chassis damage effect of whole vehicle architecture, for cars, the chassis can
ensure the safety of the vehicle and the owner. Often spray is a new car factory
anti-rust primer, but after a period of time will slowly oxidation. Once the
chassis parts rust corrosion, can cause the vehicle structure is loose, bring
safe hidden trouble, and a lot of traffic accidents caused by loose chassis.
Some manufacturers will give the car engine equipped with bottom plate, the
owner can be optional according to demand.
Chassis of daily maintenance, car maintenance projects, chassis care most easily
ignored by the driver friend, but in the winter or wet weather, chassis
maintenance.

Automotive repair and maintenance is equally important, such a small problem
owners who can solve their own, here I will introduce an automotive diagnostic
tool.A kind of Auto Key Programmer :

4D CLONING TOOL Notes:
1) Throughout the entire operation the device must be connected to the PC in the
"CONNECTED TO PC " mode.
2) Duration of the entire operation varies from some tens of seconds to some
minutes, according to the key to be copied and the power of the computer used.
How to make a copy of key with 4D cloning tool program?
If you plug 4D CLONING TOOL device in USB port first time operation system offer
to install the driver of located device.
Choose the manual installation method with point of driver directory (it is 2nd
method). Point the directory to folder "FTDI / driver " from CD. If you have
done everything correctly, then the operation system will confirm that the new
device already installed and ready to work.
Detect the number of USB port in which you plug in the 4D CLONING TOOL device.
Click by right button on "My computer " icon. Choose "System property ->
equipment->devices manager ". Open "Ports (COM and LPT) ".
The virtual COM port of device connection will located like "USB Serial Port ".
The copy works for keys used on the vehicles indicated in the specifications
attached to this document, or accessible through the INFO button in the 4D
CLONING TOOL program.
Start the "4D CLONING TOOL PROGRAM " from the Menu:
Start Programs 4D Cloning TOOL Program of the "4D CLONING TOOL " type of device
in your possession which it is connected, then click on that the program can
detect the communication. If the version of the not up to date, a special
message update.
Make sure the device is on, connected to the PC by the serial port, and the
