How to Solve Bora sedan engine immobilizer lock

When a Bora 1.6L manual transmission cars, traveling to more than 10,000 km, due to an accident causing damage to the dashboard. Owners request a replacement instrument panel assembly, has been replaced, but the emergence of anti-theft alarm lamp lit only immortal, after starting it only lasted 2s flame failure. However, even before the replacement vehicle was able to start normally.
      Volkswagen Bora sedan uses a third-generation anti-theft system, which is dominated by a combination of instruments embedded in anti-theft system control unit, a combination of anti-theft warning light meter K117 (located on the instrument cluster speedometer), matching the multidiag engine control unit ignition coil switch on the identification and matching with D2 transmitting / transponder ignition key composition. Under normal circumstances, turn the ignition switch, electronic immobilizer anti-theft alarm light on the instrument cluster will illuminate after K117 3s off. If a failure occurs, such as the following: the ignition key fit correctly; without sending / transponder inside the ignition key; ignition key without authorization; engine control unit without authorization; identify faulty coil D2 or faulty data cable, etc., turn the ignition switch after, burglar alarm light will blink or stays on K117.
      Analysis of vehicle faults that vehicles entering the security state, mainly because no new instruments in the anti-theft system control unit caused by match. Access to information, to know if the new instruments are VDO production company, from time to time to match the password, and enter a fixed code 13861. Data entered by the methods described in this fixed code, but still can not start. The unit is not an authorized special maintenance station, the public is not entitled to the original data and the corresponding technical support, so I can not know their own data entry error or a wrong, so maintenance trouble.

      Repeatedly thinking, since the original instrument can be started, but can not start a new instrument, which shows that the old meter anti-theft system control unit is not damaged. Unpack the original instrument to find a model for the 93C86 8-pin chip. At this point, I whim, can sound like anti-theft solution as the Renault can clip V139 replacement chips? So after cutting the two instruments in the exchange of old chips. After refitted, still can not start. Apart again, but found that due to the negligence of the upper and lower legs welded obvious sign of backwards. At this point, I think it may come to naught under the chip will burn no doubt, but still holding the dead horse a living horse medicine idea, the next chip re-welding, weld and refitted correctly, unexpectedly turned out to be able to start a. By using a chip inside the original instrument, the password is not changed, it is still more than 10,000 kilometers km. The use of more than 1 year, this failure never occurs again.
      Through the above troubleshooting process, we can see that for a similar situation like the Passat B5, Audi A6 and other vehicles encountered and some of the sound with an antitheft device, we can by analogy, using the same method to solve. It also allows insight into the author, in the repair process, encountered in the case of the external environment is not allowed (eg no causes of passwords, equipment and technical information, etc.), we have to use the experience accumulated in peacetime, broaden thinking solve the problem. Some may seem impossible, but also through a thorough understanding of the principles, boldly practice to verify, and sometimes you will receive unexpected results.

Car fault diagnosis method summarized

Vehicles in use, the failure phenomenon is complex. A fail phenomenon may be caused by a variety of causes; while certain reasons, they may cause a variety of symptoms.
Hyundai Motor fault diagnosis through high-tech equipment, full use of electronic control technology characteristics of the car trouble to make scientific and accurate diagnosis, thus greatly improving the level of vehicle maintenance quick and reliability. Therefore, to make a diagnosis of science, we must choose a good method of diagnosis, while the cycle of diagnosis, diagnostic parameters, diagnostic criteria, which are well understood.

Currently automobile fault diagnosis can be summarized as the following four methods
1 Experience diagnostics
The traditional method is to rely on the experience diagnostic manual observation and feel, according to the car shown in the work of external abnormalities, using logical inference methods to diagnose the fault type and location, it is also known as fault tree analysis or diagnostic table method. But this approach must rely on experience and repeatedly observed long-term accumulation of maintenance personnel, cumbersome and inaccurate, often misdiagnosis and delays.

2. Detection and diagnosis method
Using a variety of testing instruments and equipment to get the car’s various data, and based on these data to determine the technical condition of the car, called the detection and diagnosis method. Currently available for the use of the equipment are: multimeter, ignition timing light, cylinder pressure gauge, vacuum gauge, oil pressure gauge, sound level meter, flow meters, fuel consumption meter, oscilloscope, cylinder gas leakage detector, crankcase channeling gas detectors, gas analyzers, smoke meters and function relatively complete dynamometer, wheel alignment, brake tester, sideslip test rig, integrated detector engine, chassis dynamometer, etc.. These instruments provide people with a reliable basis, making the car fault diagnosis from the development of quantitative diagnosis diagnosis.

3 self-diagnostics
Use of computer monitoring and control system itself can be quickly working conditions and the characteristics of the data stored by certain operating procedures, the car computer fault codes extracted, then solve the problem, troubleshoot, this method is called self-diagnosis method. This method is very effective for major automotive electronic control systems, and fast and accurate.
Enter the self-diagnostic test state:
1, with diagnostic fault detection jumper shorting the corresponding jack socket (diagnostic input jack and grounding jack).
Such as: Toyota cars (short TE1 ??and E1); Honda cars (short A and B).
2, press the “Diagnostic button switch.” Such as Volvo cars.
3, twist “diagnostic mode selector switch” on your computer. As Japan’s Nissan cars.
4, open the “combined switch” on the air conditioning control panel. If Cadillac is the cruise control power switch and the ignition switch to “ON”, press the “OFF” and “WARMER” button on the air conditioning control panel.
5, fault detection in the corresponding jack socket jumper made ??between 330? series of light-emitting diodes. If Mazda cars.
6, the ignition switch in the switch three times in a row 5s (ON-OFF-ON-OFF-ON). If Chrysler cars.
7, ignition switch “ON”, within the specified time will be five times the acceleration pedal. Such as Germany and M5 series BMW 300,500,700,800.

Fault code display method:
An engine fault indicator: Engine failure indicator light on the instrument panel using laws to eliminate the fault code is displayed.
2, Analog Multimeter
3, using a light emitting diode
4, the dashboard display
5, the direct English Display: Display fault content directly in English.

4 Computer diagnostics
Automotive fault diagnostic computer all kinds of information (commonly known as the decoder), which itself is a dedicated small computer, it can car computer (ECU) to save extracted, and then organize, compare and translation, in clear text, curve or graphically displayed, it can send out the information, and determines the type of fault sites occurred. It also issued a directive to the car computer, static and dynamic diagnostics. This is one of the most promising diagnostic method.

Diagnostic methods summarized above four cars, automotive diagnostic methods are still evolving and changing. However, at this stage, still maintain their own characteristics, but also has its own irreplaceable characteristics, therefore, the best option is to take with each other, complement each way to achieve a multiplier effect diagnosis.

Analysis of automobile engine oil pressure fault exception

The lubricating oil is able to reach the surface, because the oil has a certain pressure, so that continuous flow. Low engine oil pressure lubrication system technology marks a bad situation, once the oil pressure anomaly occurs, should immediately identify the reasons, be excluded.

     1. Always low oil pressure
     Oil pressure sensor is usually installed in the main oil, if the oil pressure gauge and oil pressure sensor is normal, and the oil pressure gauge indicates the pressure is too low, can be analyzed according to the composition of the possible causes of failure and oil lubrication system. If the direction of the oil flow to the oil by the oil pressure sensor for the sector is divided into before and after the two leading causes of low oil pressure can be divided into two aspects: First, the lack of oil pressure sensor or oil before the oil poor; Second, after the oil pressure sensor oil drain too quickly. Despite the different engine lubrication system components and oil have some differences, but according to the above ideas, it is easy for low oil pressure fault diagnosis.
     When the oil pressure is always low, usually the first out of the dipstick to check oil quantity. If sufficient amount of oil, remove the oil pressure sensor may be a short time to start the engine to observe the injection case, if the oil pressure sensor mount hole injection, weakness, should be followed by dismantling the oil filter bypass valve, pressure limiting valve, set filters, tubing and pump; If forceful injection, you should check the oil pressure gauge and oil pressure sensor is normal.
     In addition, the engine, if the engine oil pressure is always low, and there is abnormal sound crankshaft main bearings, rod bearing camshaft bearing abnormal sound or abnormal sound phenomena deal with these abnormal sound of the bearing clearance checks. According to tests proved that every crankshaft main bearing clearance increased 0. 01 mm, the oil pressure will drop 0. 01 MPa.
2. Sudden drop in oil pressure
     Sudden drop in oil pressure failure is generally a serious oil leak, such as oil lost track plugs, oil tract rupture, will make a lot of oil leaks, engine work will be reflected in the very low oil pressure. Pump damage, such as severe wear gear pump and the pump casing, shaft and bearing between the shaft fracture regulator device failure or other reasons, the pump can not establish a normal working pressure; also may be related to machine pipeline connecting the pump connector is loose or cracked, oil strainer clogging, etc., can cause the oil pump lubrication system unable to establish normal operating pressure, thus making the engine oil pressure is low, or no pressure. After this happens, you should immediately turn off the engine, in order to avoid serious mechanical accident. Then remove the engine oil pan, focus on checking the leak site and oil pump.

     3. Engine oil pressure is too high
     In use, if the oil pressure gauge indicates the pressure is higher than the normal standard for a long time, that is, the oil pressure is too high. Engine oil pressure is too high is not a good thing, not only the oil pump load increases, but also make a normally open valve, oil filter strainer without directly sent to the friction surface, increasing the friction pair wear; If the safety valve sticking, also rushed bad strainers filter, and cause the main oil filter is clogged debris.
     By low oil pressure failure analysis always thought that if the oil pressure gauge and oil pressure sensor is normal, before the oil pressure sensor to the main oil supply too much (eg pressure limiting valve failure) or the sensor poor oil (such as oil Road blockage) will cause the oil pressure is too high. Possible reasons for the limited pressure valve failure, after plugging the oil passage sensor bearing gap is too small, too large Bo oil, oil pressure gauge or oil pressure sensor damage. For the new engine assembly, where there is oil pressure is too high, you should focus on checking the crankshaft main bearings, rod bearings, camshaft bearings with the gap. Ignition switch is turned on but do not start the engine, oil pressure gauge pointer does not return, should focus on checking the oil pressure gauge and oil pressure sensor.

     4. Just starting pressure is normal, quickly reduce oil pressure after running for some time
     Pressure is normal when the engine has just started, and after a period of operation and rapid decline in oil pressure, as has been proved that the oil inspection tables, pump and control valve trouble, you can first check the oil dipstick draw number, if sufficient amount of oil, such as determined to be too low because the oil Bo, you should change the oil. If the coolant or fuel into the engine oil sump dilution, resulting in Bo was reduced due to leaks or spills should identify, troubleshoot and then replace the new oil.
     In addition, the engine crankshaft and the bearing gap is too large, such as poor crankcase ventilation, temperature increases, hot car engine oil thinning, such as tubing or joints slight case of oil spills, or crankshaft, connecting rod, protruding shaft bearings, etc. loose, it will make the oil pressure drop very low.

     5. Low oil pressure fluctuated
     When the engine is idling oil pressure normal, medium, high-speed operation, oil pressure fluctuations (oil pressure gauge pointer swings back and forth from 0 to 0 or vibrate between 6 MPa.), The reasons are:
     (1) pump is faulty (eg excessive wear or fixed gear screw off), oil pump suction air. When the engine speed operation, increasing the suction pump air into the oil pipeline from Mifengbuyan place, because the air is compressible, causing fluctuations in oil (no oil intake severe).
     (2) back to the oil control valve or valve spring by foreign objects sticking, bending and seat hole or spring grazing, spring sports blocked, the ball valve to open and close are obviously more difficult. When the main oil hydraulic rise ball is open, the main oil pressure relief, but blocking action of the spring until the oil pressure dropped to a very low or even close to zero ball was turned off, then the main oil and rose oil , ball valve and open, and so on ad infinitum, causing oil pressure fluctuations.
     (3) sump oil shortage, oil strainer suction port is located in the plane of the limit position, or in the possession of impurities in the oil but not completely blocked, so that the pump suction from time to time, causing the oil pressure fluctuated.
     (4) the pressure limiting valve assembly or improper adhesive, so that the oil flow resistance instability, or damage to the oil pressure gauge, oil pressure can also cause peaks and valleys.

Note the use of tires daily several major problems

Car tires are the only contact with the ground of the site, to reduce tire wear, in daily use should pay attention to the following matters.

Note that the tire pressure should not cheer too full, because tires may not be due to excessive tire inflation pressure occurs at high speeds dangerous, so it should be in accordance with the manufacturer’s required to maintain the standard tire pressure, including the spare tire pressure.

Available measuring tire tire, the tire temperature, but must be in a state to measure because the tire results in a hot state is not accurate measurement.

Swap positions regularly traveling 10,000 kilometers per tire should swap positions, because the general car’s engine is placed in front of the front axle load distribution and the rear axle is not the same, so the larger front tire wear. In order to reduce this phenomenon, the best way is to swap the position of a.

Regular checks on a regular basis to detect balance balance not only to extend tire life, but also improve the stability of the car when driving.

Can not mix tires of different specifications radial tires and bias tires lateral force different if the two different tire mounted on the same shaft at the same time, it will cause oversteer or inadequate, or likely to cause skidding.

Timely replacement recommended tire life is 40,000 km or so, if the mileage is less, but also suggested the use of more than two years to replace.

The role of OBD II

OBD II” is “On-Board Diagnositics ?”, ie OBD II type abbreviations. In order to standardize the diagnosis of all new car vehicle emissions and driver-related failures, starting in 1996, who sold in the U.S., its diagnostic instruments. Fault codes and maintenance steps must be similar to that in line with BOD II procedural requirements. With economic globalization and the car is becoming more cosmopolitan, as a driver and emissions-based diagnosis, OBD II system will be more widely implemented and applied. OBD II program enables simple and unified automotive fault diagnosis, maintenance personnel without special learning every manufacturer of a new system, we can say, OBD II diagnostic repair work to the maintenance staff brought unprecedented convenience.
After OBD II program implementation, any technician can use the same diagnostic equipment to diagnose any according to standard production cars. One of OBD II mature function is lit when the system fault light, recording all the sensors and actuators of data that can best meet the needs of the diagnostic service. Countries face increasingly stringent vehicle emissions regulations, OBD II emission control monitoring system efficiency goal: With the car running in reduced efficiency, according to federal test procedure, when the vehicle emission level has reached 1.5 times the emission standards for new vehicles, light fault light and stored fault codes. Moreover, OBD II also requires some additional sensor hardware configuration, such as additional heating oxygen sensor mounted in the exhaust gas downstream of the catalytic converter. Using more sophisticated crankshaft or camshaft position sensor in order to more accurately detect misfire, all models configured with a new 16-pin diagnostic connector. As a result, the computer’s ability to greatly improve the ability to track not only the damaged parts, and meets the stringent restrictions on vehicle emissions.
