● QUESTION AND ANSWER

1. Question: What is OBD? What is a fault diagnostics tool OBD for vehicles? Is it reliable?
Answer:- OBD (On-Board Diagnostic) is an automatic electronic diagnostic system put inside the motherboard of ECU and designed separately for each kind of car manufacturers. This system is nowadays equipped in almost vehicles in the world.
- Since the 1980s, vehicle manufacturers have begun to use electronic circuits to monitor and diagnose faults of the vehicle engine. Because of its superiorities after many years of using, OBD has become a mandatory standard for modern cars.
- In 1996, a new common international standard OBD in the vehicle world - the 2nd generation of OBD (OBD-II) - was born. According to the standard, OBD-II system can provide most of information such as engine, chassis, body, safety system and accessories as well as the control information network in vehicles. Diagnostic information will be stored in memory inside the ECU in code frame of 5 characters. Diagnosis level and detail information depend primarily on the level of the sensor system and ECU on each models.
- Nowadays, OBD-II Scan tool has connected to OBD-II systems in vehicles to process data, display current parameters and give repair suggestions accurately.  

2. Question: What are the essence and working principles of OBD-II Scantool?
Answer:
- OBD-II Scantool is not a tool to diagnose faults directly from the sensor as it was before, the function essence of the tool is reading the memory storing fault codes of ECU, decoding and displaying parameters.
- You should know that, nowadays in the ECU system supported with OBD, fault diagnosis has been done in each vehicle by its own ECU. This is the private technology of vehicle manufacturers. Therefore, this tool is called fault reading tool or fault reader.  

3. Question: How many faults can OBD-II Scantool diagnose? Where?
Answer:
- At present, OBD-II system is equipped primarily for engine control systems (in the USA market, it is equipped for some other systems, too). OBD-II Scantool can diagnose almost common faults that ECU manages and controls, including: ECU, the sensor system, electric circuit, actuators, pneumatic and hydraulic power in modern vehicles equipped with the monitor sensor, engine accessories, control information network and other equipment related to the engine.
- However, nowadays most of vehicles in the markets of Europe, Asia, and Africa... support OBD-II only for the engine; the other systems are still compliant with the private standard, so now OBD-II Scantool can read only engine faults.
The amount of faults will be updated according to the development of the OBD-II system in each model and the year of manufacture so with the same diagnostic tool, each model or each generation has a different amount of faults and different diagnostic ability. The more luxury new generation vehicles are, the more faults their systems can diagnose.  

4. Question: How do I know whether my car is compatible with this tool?
Answer:
- Nowadays OBD-II Scantool is one of the first-level tools used to diagnose engine faults, it can diagnose almost cars (02 - 16 seats), light trucks using 12V battery, gasoline and diesel fuel manufactured in Japan, Europe, USA and the modern vehicles in ASIAN countries in recent years
- If you want to make sure, then there is a certification of OBD-II compliance on the “metal label" as the below image:



- 16-pin trapezium connector is J1962 standard of OBD-II and looks like the below image:



(Notes: There is a 16-pin connector in an OBD-II vehicle but not all vehicles using 16-pin connector are OBD-II compliant. For example, INNOVA, COROLLA ALTIS 1.8, DAEWOO NUBIRA are not OBD-II compliant. Mercedes Sprinter uses 14-pin round connectors but it is OBD-II compliant. We will support auxiliary-connector or wiring diagram of pin connection. .
- Check in the list of OBD-II vehicles to know your vehicle is compatible or not with OBD-II Scantool
Notes: If your vehicle is not in the list, that doesn’t mean it can't work with OBD-II Scantool, may be because your vehicle hasn’t been updated to the list yet, almost new-generation vehicles (after 2008) are OBD-II compliant.

5. Question: Where is a diagnostic connector in vehicles
Answer: A diagnostic connector is located around the area below the steering wheel

6. Question: How to diagnose with OBD-II Scantool?
Answer:
Step1:
- You (mechanicals) have to check the operation state of vehicles, determine location of faults with experience, and keep eyes on warning lights in the main dashboard.
- Identify manufacturers, models, manufacture-year
Step 2:
- Connect OBD-II Scantool to vehicles
(Notes: Do not pull battery-cables out before diagnosing faults)
- Read faults stored in the ECU. You can print, save files or simply record faults into a paper
- Use OBD-II Scantool to clear all fault codes stored in ECU
Step 3:
- Start the engine (if it doesn’t run, then negative-start about 15 seconds) and drive 200 to 300 meters to heat the engine. Try actions: braking suddenly; increasing speed, shifting transmission… to create many running states and loading states in order that ECU can get fault codes back. You could let the Check light on again.
Step 4:
- Stop the vehicle, turn off the ignition key, return on the key and read fault codes in ECU. These current faults need repairing. If current faults don’t show again, perhaps because faults of the previous repair weren’t cleared (history fault code) or you carelessly unplug some connector out and after that replug it. (After a while of driving, if the Check engine light is ON again just let the vehicle be like that and read faults)
Step 5:
- Repair or replace damaged parts, after that use OBD-II Scantool to clear one more times and reset ECU to the original state.
- Start the engine and observe the result of repair by OBD-II Scantool  

7. Question: I want to connect OBD-II Scantool to an automotive EFI trainer. Is it possible? What are necessary accessories?
Answer: Yes, it is possible. Just OBD-II Scantool is OK, no more! 

8. Question: If I buy OBD-II Scantool, will I be supported or supplied with warranty?
Answer: According to regulation, Technical warranty of OBD-II Scantool is 24 months and we will support you whenever you want. Moreover, you can update software for free. 

9. Question: The Check light is on but I can’t clear faults and turn off. Why?
Answer: Check light is on, which means it’s sure that there are fault codes stored in ECU memory, it can be almost understand that your vehicle has faults.
However, there are some below cases:
Case 1: Someone removed battery cables or sensor connectors and after that, he plugged them back and there is no equipment to turn off Check light and clear fault codes stored in ECU. Therefore, in this case, we call it “history faults code” or “virtual faults”. Thus, you can clear fault codes stored in the ECU and turn off the Check light without any problem.
Case 2: Your vehicle actually has faults (temporarily call current faults). After clearing fault codes stored in the ECU, your vehicle system will immediately recover and store fault codes in ECU as it was. The result is the same as you cannot turn off Check Engine Light. It means that it’s impossible to clear faults. In this case, you must replace damaged parts or repair broken circuits, after that you can clear the Check light fault with OBD-II Scantool.
Case 3: some vehicles, you need to clear the Check Engine Light in condition that the engine doesn’t work. Therefore, so you need to turn off the engine, just turn ON the ignition key and then clear faults.
Case 4: In some cases that there are error programming in ECU, so it is impossible to clear “virtual faults”. You should unplug more some other connectors and replug them all. Now, you can use OBD-II Scantool to clear.  

10. Question: After clearing faults, I drive my car for a while and then the Check light is on again. Why?
Answer: First, you should know that all diagnostic tools clear faults in ECU only. Perhaps parts of your vehicle are broken (Ex: broken circuits, short sensor, circuit-fire...), you must repair, replace and after that clear fault codes stored in the ECU and the Check light will be off. If the Check light is on when driving after clearing faults, it’s sure that is because of current faults and your vehicle need repairing. By our experience, maybe there are faults of O2 exhaust sensor, engine-temperature sensor... or Cam-position sensor with weak signals. You need to determine exactly these faults error with your equipment. If OBD-II Scantool cars diagnose faults of O2 exhaust sensor although your vehicle is still new, you can simply unplug the sensor after that clean and replug it. At last, clear faults.  

11. Question: My vehicle actually has problems, but OBD-II Scantool can’t read faults out. Why?
Answer:
- As we have said, the general principle is that OBD-II gets out all fault codes stored in ECU. If there is anything, it will read it all. Otherwise, it can’t read anything. That means all depends on ECU and the modern level of the diagnostic system in your vehicle. Therefore, if your vehicle is not equipped with many sensor systems, ECU doesn’t control parts, so it’s impossible to determine faults although your vehicle actually has faults. Any scanner has this general principle. According to our experience, the more modern vehicles are, the more efficient fault diagnosis is. Ofcouse for old-generation vehicles, it will be less efficient. Faults mainly relate to electricity, especially input-signals of ECU. For other mechanical faults such as: warped surface, broken glass or lamps, scratched paint..., there is no suitable tool now.
- There are also some other probable causes: ECU lost the main power supply, there are software faults in CHIP, or circuits burned on the part of the data connection. In these cases, it is impossible to connect OBD-II Scantool to your vehicle.
- In brief, faults that are diagnosed make up only about 60% of all faults. Therefore, Scantool is just a support tool, a high-skilled mechanical is still the most important.  

12. Question: I have already determined faults, but information is not detailed so I don’t know how to repair it. Can you show me how?
Answer: Maybe you are using an old version. Update a newer one! From version 4.1, information is very detailed. However, if you do not have much experience, you can telephone us to ask for an advice or support information. 

13. Question: How to know they are current faults? What is experience in determining faults with a diagnostic tool?
Answer: At best, take your vehicle to the workshop and require mechanicals to repair it for you. You should follow these steps:
- Read faults while the engine is hot and has faults (the Check engine light is on) and print or record on paper.
- Turn off the ignition key, clear fault codes stored in ECU one or several times (in order to clear “history faults” or “virtual faults”)
- Restart the engine and drive for a while in speed-modes as much as possible.
- Read faults again, if faults appear, they are current faults that need repairing or replacing. Compare these faults with previous faults for reference and exclusion.  

14. Question: When I read faults in other vehicles, I can find out faults of injector and high-voltage ignition. However, I can’t do it in my vehicle. Why?
Answer: This completely depends on the software programmed into ECU as well as sensor system equipped in your vehicle. In another case: you try to unplug a connector but the engine is off so it cannot identify. You should unplug that connector when the engine is ON, it must be OK. There is one more case: in some vehicles, ECU is programmed that if the signal is outside a specified range in the time longer than 15 seconds, it will determine faults and turn on the Check Engine Light.  

15. Question: Are there tools able to read ABS, AT, SRS, Body, IC...?
Answer: At present, OBD-II Scantool is a specialized tool used to read faults in the engine electrical system and mechanics, which relate to the engine. Determine faults of other systems such as ABS, AT, SRS, Body, IC. You should buy other specialized tools to read these accessories introduced on our Website
 
16. Question: My vehicle is still working normally, I do not feel that it has faults, so why is the Check Engine Light on?
Answer: Maybe you unplug a connector and after that replug it (example for clean your vehicle or something else) when the ignition key is ON or you are replacing oil for it. Another cause is weak unstable signals of sub-sensors (sub-sensors are not important). You had better check with OBD-II Scantool to get exact information. 

17. Question: Why cannot I use OBD-II Scantool for vehicles using 16-pin connector produced in 2005?
Answer: You should understand that OBD-II compliant vehicles have 16-pin trapezium connector (J1962) but not all vehicles using 16-pin connector are 0BD-II compliant. For example: Daewoo Nubira, Toyota Innova, Prado, Altis 1.8, Camry 2.4G, Mitsubishi Jolie, Lancer, V6... manufactured in ASIAN are not OBD-II compliant. Therefore, perhaps your vehicles are OBD-I or M-OBD compliant (Click here to get FAQ of OBD-I Toyota tools). In this case, you have to OBD-I tools from us. 

18. Question: My friend, after repairing his vehicle, he just unplugged the battery cable to turn off the Check Engine Light. That’s all, everything is OK. However, I can’t start the engine of mine anymore. Why?
Answer: Because your friend’s vehicle is OBD-I compliant and uses an old model of ECU memory (EEPROM). Therefore, he just unplugs the battery cable to turn off the Check Engine Light. However, your vehicle is OBD-II (2nd generation) compliant and use ECU memory of Flash Technology so you can’t do that by unplugging yours. Moreover, other functions in OBD-II compliant vehicles such as Radio, ECU, Immobilizer, and Security, can be reset so your engine can’t run. Another cause: ECU is programmed that if there is any fault code, your engine won’t run. In this case, you have to reset the system with OBD-II Scantool. Everything will be OK.
 
19. Question: So when I need to replace the battery, what should I do? If the battery is weak, is the Check Engine Light on? Is there any suitable tools?
Answer: When you need to replace the battery for modern vehicles, you should replace it when the engine is running. If the battery is weak, the Check Engine Light (There are some vehicles having the Check Battery Light) will be ON and we have tools to read this fault.
 
20. Question: No sooner has the engine gotten hot than the Check Engine Light is ON. Why?
Answer: You have to use OBD-II Scantool to determine accurately. And as we said (in question …) that is commonly due to O2 exhaust sensor or engine temperature...  

21. Question: I just change oil, then the Check Engine Light is ON. What is the cause? Can your tools make the Check Engine Light OFF?
Answer: When you replace oil, that is like the faults of no oil, so the oil sensor will inform ECU and fault codes will be formed and stored in ECU memory, so the Check Engine Light will be ON. In this case, you just use our tools to clear fault codes stored in the ECU and reset the system, the Check Engine Light will be OFF. 

22. Question: When I read fault codes for my friend’s vehicle, all current parameters are displayed. However, why is only N/A displayed for my vehicle?
Answer: Because your vehicle is not equipped with that kind of sensor so that information is not available, only N/A (Non Available) is displayed.  

23. Question: When I unplug a sensor connector in a Toyota vehicle and right after that I replug it, and it is also displayed in the scanner. However, for some vehicles such as Hyundai, there isn’t anything. Why?
Answer: As you said, it is just the design of each manufacturer or the programming of different kinds of ECU. For some vehicles of GM, Hyundai..., when you unplug the sensor connector, (then you replug it) after 15s ECU determines faults but before 15s it doesn’t. This also is a convenient improvement for drivers and mechanicals to limit “virtual faults” at most. However, it has its own imperfection.
 
24. Question: When I unplug some important connectors such as ignition bobin or injector and then read faults, but OBD-II Scantool cannot read?
Answer: Because the sensors and the actuator can work only when the engine is running. To clarify this problem, simply unplug connectors while the engine is running or negative-start to make the engine turn round in a few seconds. Now OBD-II Scantool can read faults. 

25. Question: If the old-generation vehicles are not supported with OBD-II standard, then what kind of tool should I use? Where can I buy them?
Answer: You should buy OBD-I tools produced on this website. 

26. Question: I want to watch tools working

28. Question: When my computer is broken-down or attacked by virus, I must format hardware and then reinstall Windows. So how should I do with OBD-II Scantool?
Answer: Very simple! You only need a CDROM attached to your tool and use it to reinstall the program. Remember to reinstall USB converter and choose suitable ports after installing. 

29. Question: What are breakdowns which often happen to DTDAuto tools? How to repair?
Answer: When you say “breakdowns”, that is not completely right. All depends on how you use tools. The most common case is after a while of using, tools are attacked by computer virus. Therefore, you must reinstall Window and then install software DTD-Code in your computer but don’t change the default connection-port in software to make it suitable for a current port in your computer. To solve this problem, just choose a connection-port and install following to the guidebook.
