Re: Nissan Qashqai SRS diagnose

Hi. Multimeter is not able to activate the airbag module in measurement mode. Little current and little voltage. But it is strictly prohibited by all manufacturers for safety purposes. Those cranks from you-tube who activate an air bag module do it with large voltage and current. The SRS ECU has dri...

Re: ignition passat b5 1.8 ADR 1996

For some old-style ECU it is normal have multi-spark mode when you have cold start RPM or RPM less 400 .
ADR has Motronic M3.8.2 .
It is normal for it, I guess .

Re: Battery drain

There is another method, to use a current sensor,used in the automotive eq. In particular the sensor used by Honda in BCM. This sensor is very heat stable and accurate.To improve sensitivity ,it is possible wind 10 turns and placed into the sensor window.Turning on the osc into the recorder mode,you...

Re: fuel pump rpm

On the waveform You can see the current consumed by the pump,the difference between the maximum and minimum current,number of lamellae on the rotor,the speed of rotation.For most pumps turbine type , the value of the speed of rotation is about 4400 - 5200 at a voltage of 14.4 .The difference current...

Re: Engine mechanical test

Sorry for my english.Most of all A/C sensors have range like this (1) ,all of them have liner and thermostability characteristic . So,- on diesel engine, they will fit only on cranking or compression test.On gasoline engine they will work on crankig ,idling and even part load in working cylinder .Fo...

Re: misfire detection by engine speed signal.

Some digital oscilloscopes have such soft.They are very useful because they help to identify difficult cases in the diagnosis of the mechanics of the engine, when the normal gauge or pneumotest useless or difficult to use.

Re: Clio 1.5dci cutting out.

If you have K9K , trouble code DF137 and that waveform in comparison with standart, one of the reasons - wrong pressure regulator.May be there is no correspondence between the control current, and a high pressure .Sometimes it may help flushing and blowing out with compressed air after removing pres...
