Re: Lexus RX330 2005 - CSS Test

The blue graph indicates that cylinder # 4 is not operating under load. First, replace the spark plug in this cylinder and then repeat the test. If nothing changes, replace the ignition coil. If nothing changes, replace the fuel injector. In the process of performing these checks, it is not necessar...

Re: crank and cam sensor mitsubshi

Apparently, you have incorrectly connected the black crocodile of the device's power cable: it must be connected to the car body; You connected it to the "-" battery terminal. Because of this, inductions from high currents flowing through the car ground are superimposed on the useful signal. In this...

Re: Funcion Elpower

Hello, The alternator was broken and produced too high voltage. During the first measurement, there was not enough time to observe this; but you observed this during the second measurement. The starter circuit was able to accept only 880A (according to the CCA standard) and, apparently, this was not...

Re: Hyundai 1.5 HDRI Turbo Diesel

In a diesel engine the fuel is ignited by the high temperature of the gases compressed in the cylinder. The main cause of misfire is that, AT THE TIME OF FUEL INJECTION THE TEMPERATURE OF THE GASES COMPRESSED IN THE COMBUSTION CAMERA IS INSUFFICIENT to heat, to ignite the injected fuel. It is very i...

Re: Toyota Etios 1.3

Hi,
I think standard Pico adapters don't work properly because of wrong construction.
There is a parasitic volume that distorts the measurements.

It's better to ask about WPS500 deep well adapter directly support@usbautoscope.eu

Re: Erro scritp CSS Honda Fit 1.4

RE: 1. To solve the power problem of the CKP sensor power, use Remote Power Off device. 2. The reason for the uneven operation of the cylinders at idle (and, in particular, the worst operation of cylinder #2) is the unequal composition of the mixture in different engine cylinders, that is, the unequ...

Re: Flexray

Yes, you can use the PIN3-BNC adapter together with the high-frequency oscilloscope probe, the distortion from the parasitic capacitance of the cable will be minimal. PS: Here, the pulse repetition frequency is 5 MHz, this is theoretically the upper possible limit of the bandwidth, which could be me...

Re: Attenuators?

Hello, Yes, level-over-range warning is off in Ignition_Primary mode. Because ignition primary voltage can reach as high as 400V, and buzzer warning will be annoying during all measurement time. We don't have attenuators with the XLR connectors. Alternatively, we can offer you to use PIN3-BNC adapte...

Is there a tool or fixture that could be used to hold the Lx-M against the ignition coil during this type of testing?
No, the Lx-M should be held by the hand.
