Cars broken once the computer can pull to correct the pc, the next test tool accustomed to launch x431, lexia3, mb star. Here are a few computer malfunction:
The very first is area of the computer power failure. Generally since the vehicle charging, the charger current regulation because of excessive, or corrected polarity or charge while opening key, or perhaps start the motor, or engine during operation, resulting in the battery connector loose generator straight to your pc board power along with other reasons. Generally this will burn high-power components for example current regulator diode, change could be relatively simple to correct.
The second reason is the input / output area of the fault. Amplification circuit element is generally burned, sometimes supported by follow-steel lines blown circuit board. For instance: a repair center in Taiwan and USA Chevrolet sedan on the renovation of paint and located the engine can’t start, and when you open the keys with time, gasoline in the exhaust pipe, oil pan, etc. overflow. Open the keys and located that six fuel injectors are fully open condition, gasoline from the nozzle in to the cylinder, flow over following the overflow, look into the exterior circuit found no problems, it may be came to the conclusion the creation of the pc control failure. Recognition techniques may be used is launch x431. Open the pc situation examination revealed nozzle control signals around the amplified high-power transistor includes a breakdown short circuit, causing power nozzle which are open condition. Substitute of the similar kind of transistor and cleanup after changing engine oil, the engine can operate normally. To notice here: Many EFI automobiles through paint, then start all sorts of problems frequently occur, because following the vehicle interior with the paint, particularly in circuit accrued heat inside the tool and heat, and also the heat from inside gradually comes from the depths, and electrical equipment to operate easily within the hot temperature failure. Therefore, don’t immediately drive the18 wheeler out after baking, but ought to be cooled with the full start, if producing stress have to free paint room, you should use human capacity to push the vehicle, allow it to awesome lower, the re-start.
Another part may be the memory failure. As many as four types of memory, read-only memory (ROM) can be used to keep computer monitoring program the computer itself, a few of the methods that must definitely be run. Prrr-rrrglable read-only memory (EPROM or EEPROM) is principally accustomed to store for that implementation of products or any other control products for that control program. For example: fuel injection control, ignition advance position control. Idle speed control and self-diagnostic methods. Ram (RAM) for temporary storage of information from various sensors for CPU use even the fault code storage systems. Random memory contents will appear reduced following the power failure. Have to know this recognition technology lexia3. Adaptive memory (ram owned by a) for that computer’s “self-learning” as well as in compliance with vehicle speed, instantly changes the parameters. For example “idle learn” and so forth. To get rid of the prrr-rrrglable memory (EPROM or EEPROM) problems could be changed, must find a properly-known memory nick with program content, purchase a blank nick using the model, by author, in the browse the original film program, after which to create to some blank nick, new nick could be replicated, and so the new nick in to the computer. But many vehicle producers are established to only copy 3-7 occasions greater than the amount of after no more using, and a few producers make chips by way of an file encryption cannot be replicated.
Last situation is really a special failure. Off through the flooding of automobiles, computer systems plate corrosion happens, the component pin circuit, adhesion or component damage, can repair or replace components by check. For instance: a repair center received a Cadillac vehicle repair, fault phenomenon: once the normal operation from the engine when the on and off car headlights or any other electrical equipment, exhaust pipes raging phenomenon happens, the exhaust pipe could be serious burst. Better recognition technologies are mb star. The inspection discovered that the exterior circuit isn’t the problem, suspect faulty computer, open the pc box carefully supervised and located that the ground wire for corrosion circuit, the grounding lines are the oxygen sensor signal shielded cable within the computer grounded with the location, because Duanlu to shielding failure, brought on by oxygen sensor signal interference brought on by other home appliances, having a tin solder over time, that’s normal again.
They are some common computer failures is going to be experienced in the work a number of fault phenomena, as lengthy like a obvious principle, and get in a certain style, evaluate specific issues, finally includes a solution.
