Follow the circuit diagram (Figure 2) to continue to check the engine control module (DME) power supply and ground situation.

Measured, the voltage of the wire connector X60006 terminal 1 is 12V (normal), the voltage of terminal 2 is 12V (normal), the voltage of terminal 3 is 0V (it is normal and should normally be 12V).

The above test results indicate that the problem is on the line to which the terminal 3 is connected. The power supply of the engine control module (DME) is supplied by the No. 1 relay (DME main relay) and 3 fuses (fuses F01, F02, F03) in the integrated power supply module, which means that the terminal 3 is not energized. The fuse F01 on the power supply module is kess v5.017 , but the fuse F01 is integrated in the integrated power supply module and can not be replaced separately.

    So, why is the integrated power supply module burned?

With the doubt to continue to measure, measuring the integrated power supply module fuse F01 output terminal 2 and ground turn on the situation, disconnect the ignition switch with a multimeter conduction test, a test pen connected to the power supply kess red PCB module side of the terminal 2, the other The test leads are disconnected from the engine connector, and the line is no longer conductive when the wire connector X60002 is disconnected.

According to the terminal description of the wire connector X60002 given in the maintenance manual, the faulty code is used to check the parts with the fault code. After the measurement, it is found that the DISA (two-stage variable intake system) servo xhorse VAG MM-007 Scanner motor 2 on the wire connector X60002 The terminal 21 (the DISA servo motor 2 supply terminal) and the terminal 35 (DISA servo motor 2 ground terminal) are VAG MM-007 turned on and off. Remove the intake manifold and find that there is water in the intake manifold where the lower part of the intake manifold DISA2 is present.

The water passes through the flap into the inside of the DISA valve, causing the DISA valve wire connector to burn out due to short circuit (Figure 4), causing the integrated power supply module to burn out.

    Troubleshooting: replace the DISA valve and integrated power supply module, and KESS V5.017 Red PCB clean the intake system after the test, the X100 KEY Tool engine starts and run properly, troubleshooting.

The two signal waveforms of the intake camshaft are merged, resulting in malfunction of the sensor function. The reasons for signal merging are: MB SD C4 Diagnostic tool sensor hardware failure, sensor installation location failure, signal generator failure. Because the sensor has been replaced before, you can exclude the sensor MB SD C4 hardware failure; because the sensor mounting position is fixed, so they measured the camshaft 4 signal leaves to the fixed sensor position, the results show that there is a signal leaf and the other three signal leaves The distance is less than 0.9mm.

    It is this 0.9mm distance leading to the MB SD C4 sensor signal acquisition is not normal. Use the tool to correct the deformation of the signal leaves, measurement meet the requirements, install the sensor, remove the fault code, start the engine again, the engine on the instrument failure alarm light is no longer lit. Go out to test, everything back to normal. At this point, the car's fault was really completely removed by hand.

 

    Maintenance Summary: This car Opel Opcom v1.95 in the replacement of the camshaft after the failure, over-reliance on the computer given the diagnostic results, while ignoring Opcom V1.95 the meaning of the first fault code, that is, the sensor function failure, and no analysis of the system control logic, Which led to miscarriage of justice, and missed itself without failure of the intake camshaft adjustment sprocket and Opel Opcom control valve. It can be seen, to become a good car diagnostic division, it should be like the detection of suspense case, can not let go of any clues, so accurate analysis, lean evidence, in order to better and more accurately find the real source of failure.

 

    Expert Comments: After reading this article, I was very dissatisfied with the heart. As a front-line technical staff, but also high-end brand vehicle maintenance of Launch X431 V 8 inch technical personnel, in the troubleshooting, is this to carry out troubleshooting repair it?

As a modern vehicle maintenance, the use of professional equipment has long been commonplace, after reading the fault code, in addition to follow the Launch X431 v instructions in the maintenance manual to check, the use of oscilloscopes to verify the fault waveform is also necessary to do the work, so that more Accurately find the cause of the X431 malfunction, unfortunately, the author did not do so, which also laid the foreshadowing for the subsequent failure.

Several kinds of car ECU introduction

Le 12 septembre 2017, 08:18 dans Humeurs 0

Hyundai Motor in order to meet people on the car comfort, safety, economic needs, continue to increase the electrical equipment on the car. With the car ECU Programmer kess v2 v5.017 on the electrical equipment continues to increase, the car circuit has become increasingly complex, the difficulty of reading the car circuit diagram is xtool x100 pad constantly increasing. In fact, read the car circuit is not difficult, before reading the car circuit, you should first understand the basic composition of the car circuit.

    Throughout the car vehicle circuit, it is not difficult to find the car circuit is composed of XTOOL X100 Pad key programmer  many basic circuits and electrical equipment. The use of the relay circuit in the control circuit can be divided into direct control circuit and indirect control circuit. For the power circuit, the signal xtool x100 pad circuit and the actuator operating circuit. When x100 pad reading the car circuit diagram, you can follow the above points of the first circuit is divided into different types of circuits, and then class analysis and interpretation, read each type of circuit, but also read the vehicle circuit.

In reading the direct control circuit, the key is to kess v2 follow the principle of the circuit, that is, the electrical work must be in the battery positive, overload protection devices (such as fuses), the controller, electrical appliances and battery anode between the closed loop.

Kess v2 firmware v5.017 ECU Programmer

As shown in Figure 1-1, the circuit is the kessv5.017 battery positive pole the instrument panel fuse F20 10A (overload protection device) reverse switch (controller) turn the light (electrical) G401 grounding a battery negative.

    Multi-function combination switch is another important switch for the  kess v2 firmware 5.017 control of electrical appliances, including lighting switch (headlamp switch, variable light switch), signal switch (steering signal switch, dangerous warning light switch, overtaking light switch), block Wind turbines, wipers and washer switches, etc., installed in front of the driver's steering column, easy to control the driver.

 

    Fuse is the most common overload protection device when the vas5054a diagnosis  on the car, for the protection of local circuits can be rated current for a long time working load, but when the current exceeds the rated current of 25%, about 1min on the fuse, in vas5054a excess of the rated current 10%, then 3min on the fuse. So the fuse in the structure of a certain time, the greater the current flow through the fuse, fuse farther the shorter time. The fuse is a one-time protection device, after the fuse, can only replace the new fuse.
