IF YOU’RE HAVING A PROBLEM ABOUT GM TECH2

Oct 03
Posted by vtool in GM Tech 2

This appendix describes some of the possible problems which you might run into when you try to use the Aian Imports Software on an OBD II compliant vehicle.
1. OBD II Interface Circuitry Not Installed Possible Cause:
a. OBD II Interface Circuitry is not istalled in the Tester.
Recommendations:
· Verify that the vehicle’s ignition is on.
· Remove power from the tester by unplugging the DLC cable and reconnecting the cable.
· Verify that the OBD II Interface Circuitry is installed in your tester in one of the following configurations:
- an OBD II Interface Cartridge is installed in the top slot of the TECH 1A.
- a Vehicle Interface Module (VIM) is connected “in-line” with the serial data cable for either the TECH 1 or TECH 1A.
- an OBD II compliant daughter board inside the Mastertech
IMPORTANT:
The OBD II Interface Cartridge will not work with a TECH 1. An error message, OBD II INTERFACE CIRCUITRY NOT INSTALLED, will be displayed if you attempt to use the OBD II Interface Cartridge with a TECH 1.

2. TESTER is Unable to Communicate with the Vehicle.
Possible Causes:
a. Vehicle’s ignition is off.
b. Diagnostic cable is not plugged into vehicle’s diagnostic connector.
c. Vehicle is not OBD II-compatible.
Recommendations:
· Verify that the vehicle’s ignition is on.
· Verify that cable is plugged into vehicle’s diagnostic connector.
· Check underhood decal for OBD II certification.

3. TESTER Loses Communication with the Vehicle
Possible Causes:
COMMUNICATIONS
a. Vehicle’s ignition was turned off.
b. Diagnostic cable came loose from vehicle’s diagnostic connector.
c. Vehicle failed to respond to query from tester.
Recommendations:
· Verify that the vehicle’s ignition is on.
· Verify that cable is plugged into vehicle’s diagnostic connector.
· Turn tester and vehicle’s ignition off. Then turn ignition to on, followed by turning on the tester and attempting to reestablish communication.
· Some vehicles fail to respond properly to tester queries for certain tests.
This is particularly true with oxygen sensor tests if all readiness tests have not been completed. If possible, drive the vehicle to complete the readiness tests and then rerun the tests.

4. Parameter Update Rate is Slow
Possible Cause:
· A slow update rate is characteristic of OBD II communications. A typical update rate is approximately 125 to 150 ms per parameter (7 or 8 updates per second for a single parameter). Therefore, a typical list of 20 parameters will only be updated approximately every 3 seconds.
Recommendation:
· If a faster update rate is needed, select fewer parameters using the CUSTOM LIST function. Select only the parameters needed for a test.
For example, you can look at just an oxygen sensor signal and get an update of 7 or 8 times a second.

5. Not All Parameters Displayed
Possible Cause:
· The vehicle is not reporting all of the parameters. The Asian Imports software queries the vehicle’s ECU to determine what parameters are supported by the ECU on OBD II compliant vehicles. The tester then creates a data list based on these parameters. If the vehicle contains a particular sensor, but does not tell the TESTER that it supports that parameter (e.g. a downstream oxygen sensor) the software will not display that parameter.
Recommendation:
· Diagnosis must be performed based on other diagnostic data or procedures.

6. Tester Displays “TEST RESULTS” Message
Possible Cause:
· This mode is not supported by this vehicle.
Recommendation:
· Try a different test mode. This display can occur in the O2S RESULTS mode if the vehicle manufacturer supports O2S testing via a different mode. Some manufacturers use the non-continuous version of the ON-BOARD TESTS mode to report the results of oxygen sensor testing.

7. Wrong display after power is applied
Possible Causes:
· Wrong master cartridge is installed.
· Master cartridge is malfunctioning.
· Tester is malfunctioning.
Recommendations:
· Verify that the cartridge is installed in the bottom slot of the tester and that there isn’t a master cartridge (e.g. “E/K 86-87 SYSTEM”) in the top slot.
· Try another cartridge.
· Perform the Self-test as described in the Operator’s Manual.

Diagnostic for Hyundai Car

Jun 04
Posted by vtool in car diagnostic tool

Hyundai Motor Co. (005380) has made steady progress in China in recent years by courting consumers on reliability and price. Now it’s betting that a new factory and an updated version of its top-selling model will give it the edge it needs to further boost sales of both small cars and more expensive — and more profitable — x431 diagun vehicles.

Hyundai this month will open the 6.5 billion yuan ($1 billion) Beijing plant, where it plans to produce Elantra sedans that are slightly longer and taller than the current model in a bow to the Chinese penchant for space and spice in cars. The company expects the extra legroom and snazzier look to help it gain market share in China’s small-auto segment, where demand comes predominantly from people purchasing their first car. That, in turn, could help Hyundai as those buyers trade up.

“Chinese customers want even what we would consider a volume car to look as premium as possible,” said Frank Ahrens, Hyundai’s director of global public relations. “The Chinese taste is moving up the scale to larger and mid-size cars and we think we have that for them as well.”

The Seoul-based automaker, which made its first car in China a decade ago, has increased its share of the world’s biggest vehicle market to 6.1 percent from 3.9 percent in the past five years, gm tech2 according to auto association data. The new plant will boost Hyundai’s local production capacity by 67 percent, helping narrow its gap with industry leaders Volkswagen and GM.

Readout of Fault Code in Automotive

May 29
Posted by vtool in car diagnostic tool, GM Tech 2, X431 MASTER

Self-diagnosis System
The fault in vehicle electronic system is stored in KAM of ECU as fault code. The fault code can be read out by the on board diagnostic system or external gm tech2 scan tool.

The on board diagnostic system in different vehicle may indicate the fault in different way. In general, the following ways are popular:
- Blinking of fault indicators on the instrument panel
- Swing of multimeter index
- Blinking of red/green LED on ECU
- Shown by a special device

The more intuitionist way for showing the fault is by external scan tool.

The diagnostic system of modern cars is equipped with diagnostic socket or DLC (data link connector). Fault code in vehicle ECU can be read out by connecting a scan tool to the diagnostic socket. In early time, each vehicle system had its own type of diagnostic socket. Since 1996, SAE has specified a uniform system called OBDII on board diagnostic system. Each vehicle that is made in accordance with the system may have the same diagnostic socket, same definition of pin and same description of fault code. The control units of every system are connected to bus, so only one diagnostic socket is needed for readout of fault code. OBD provides the possibility of reading data stream and displaying working status of switches and actuators. Moreover, external scan tool can send commands to activate the actuators.

X431 Master is such an external scan tool for vehicle diagnosis. It not only has the diagnostic function like reading fault code, reading data stream, actuation test, displaying sensor waveform, coding control unit, etc., but also has PDA function.

Vehicle Maintenance In Spring

May 22
Posted by vtool in car diagnostic tool

Each year when the car to change garments according to the should do something to maintain? I believe that this is a lot of owner are concerned about the problem. Generally want to do is: car maintenance, the gm tech2 maintenance, the appearance of routine maintenance.

First. Car appearance maintenance
Acid rain contains composition to be in the car paint a strong corrosion function, long time will be to paint cause damage, therefore, before the arrival in the rainy season, conditional word, can give the car “wear” an invisible coat, prevent paint fade and aging, this is what we usually do seal glair, coating, polishing and waxing. But suggested new car wax don’t literally, because new car’s paint itself has a layer of protection wax, early waxing can only be waste;

Second. Car maintenance
General winter rarely ventilated, in-car amassed a bacteria. Spring bacteria, viruses tend to produce, so this season to let the car keep you dry health, especially to cushion, outlet more to do these blind Angle cleaning work, keep the environment inside of dry clean and tidy. Some owners because don’t like air conditioning open to high block of the noise when, so rarely or never will be open to the big air volume air conditioning. Air conditioning usage sucked into a lot of dust when, regularly open air conditioning duct winds can the inner surface of floating dust blow out, this is to keep the air conditioning clean a simple method. In addition, also want to use special air duct cleaning solution sterilization, cleanup and divide peculiar smell.

Third. Routine maintenance
- Clean carbon: the engine of the car in the winter cold short distance running condition use under, it is very easy to form around the valve in a thick layer of coke, affect the normal driving car, so the engine in the inlet and nozzle cleaning;
- Air filter inspection: the car air filter is equivalent to the person’s nose and air into the engine should pass the first hurdle, its role is to filter out some of the air suspension particle, so as to make the air into the engine is pure, like this can make the engine working normally. Spring sandstorm and damp, and the air filter clogging easily, at this moment, the engine will appear not easy to start, idling instability wait for a symptom, so will the air filter cleaning and to change;
- Brake fluid examination: brake fluid with strong absorbent. If there is water into the brake fluid, in the process of braking, the friction produced high temperature can make water boil. And gas has the compressibility, in the brake fluid is compressed, can cause brake failure even failure;
- And the air conditioning system of inspection: spring sandstorm is big, LiuXu much, these will touch in the air conditioning filter, breeds bacteria, to produce stale air conditioning, so best every spring after a replacement. And at the same time will be between water and condenser clean thoroughly; The rainy season check air conditioning osculum, AUTOBOSS V30 prevent water flowing into in-car cause indoor water corrosion car carpet floor, vehicle wiring harness and produce stale.

Put on your hazards and fault code by obd code reader

Apr 17
Posted by vtool in obd code reader

OBD II system with MIL OBD I system has many different. In 1996, for example, the GMJ-N-and H-body car, when drivers in not correct procedure refueling, MIL lamp. In the car, OBD II system obd code reader application of the system to check vacuum EVAP air leakage. If the flap raises not cover tight or is fueling up, when the ignition switch in the open or engine idling, it will trigger fault code P0440, cause MIL lamp. So, drivers will be inconvenient, GM solution is to provide modified version of OBD II software, to EEPROM reprogrammed, make the vehicle in the road to EVAP self system.

Inferior gasoline can also cause light put on your hazards. When the vehicle diagnosis, random of fire can be found fault code, it is usually caused by the following reasons: the vacuum of leakage, low pressure, fuel injection nozzle dirty or ignition, etc. Since the diagnosis system can OBD II tracking of fire until the individual cylinder, rate of fire below 2% as normal. But if there is water in gasoline or any other reason gasoline quality drop, can lead to rate of fire more than the limit and trigger fault code.

In order to reduce MIL light opportunity, OBD II system design regulations as follows, one kind of fault need in the same running condition to detect twice, MIL lamp to light. And another kind (those who can immediately set emissions significantly increased) fault, it just detect a, MIL lamp light up immediately. So, in fault diagnosis, should distinguish fault code type. OBD II gm tech2 will fault code into A, B, C and D four types.

A kind of fault code is the most serious type of, occur only once, and trigger MIL lamp. For diagnosis is convenient, when A kind of fault code is set, OBD II system also stored A historical fault code, record and A frame the failure data.

A class B fault code is a serious problem of a class of emissions. In MIL light before, this kind of fault should be in two successive the course of driving all occurs at least once. If in a driving occurred in the process, and in the next time the course of driving not happened, the fault code is not “mature” MIL lights on. When light conditions meet MIL, the stored history fault code, failure records and A frame field data and trigger A kind of fault code is the same.

The mentioned running process (or circulation) not only be a ignition circulation, but a warm-up circulation, namely starting engines, vehicles let cooling fluid temperature at least 22 ℃ (if temperature is below 72 ℃ starting).

Once A class or A class B fault code has been set, only three times in through the continuous process of running the system after diagnosis OBD II, MIL lights will go out. If a fault involves like P0330 random of fire or fuel balance issue, so only when OBD II digimaster 3 system through and trigger fault code in the same condition (allow error: engine speed = 375 r/min, load = 10%) since the diagnosis, MIL will put out. If the problem persists, the employer for the way if to PCM codec with or without electricity, clear the fault code, MIL may return light.

If a sensor to disconnect, MIL lamp will not necessarily to light, it depends on the extent of the impact this sensor emissions (priority) and OBD II to the clinic driving cycle number. C and D class fault code and emission problems without obvious relationship. C fault code light MIL lights (or other alarm lamp), but D class fault code not light MIL lamp.
