Canbus issues

Hi, The attached waveform is from a Ford Kuga suffering can communication issues between engine ecu, abs module and instrument cluster, Can anyone explain the anomaly in the middle of the waveform, I have disconnected all ecu's and it still appears, going around in circle's with this one, also doesn...

Crank maths misfire

I am looking a bit of advice on the attached waveform, I know that the car needs number 1 injector due to excessive leak back. The trace has the following; Channel A (Blue) - Fuel rail pressure Channel B (Red) - Injector sync Channel C (Green) - Crankshaft sensor Crank Maths channel (Black) What I a...

Help understanding maf waveform

Hi, I have a Renault Trafic that I have checked the maf on, I suspect it’s either a maf issue or sticking egr valve (down in power & no fault codes) the egr isn’t accessible without a lot of stripping, how can I determine using the maf waveform which is at fault? See attached waveforms for reference...

Cylinder identification

Hi, I have a 2006 Landrover TD5 15p engine code that is down in compression in one cylinder, I have captured the attached waveform but I am struggling a bit to identify the cylinder. The sync used is on cylinder no.1 injector connected to channel B and relative compression on channel a using voltage...

Crank Maths Channel

Hi, I have read the tutorial and have watched a few videos but I cant work out how to get the crank maths channel for the attached waveform. It is from a Landrover 2.5 TD5 engine and I am trying to check for an engine misfire at initial startup, channel 1 is the ckp and channel 2 is injector no.2 an...

Ta325 on ev circuits

I have an ta325 that I want to use to view the phases on an electric vehicle motor, I have it fitted around 3 of the wires and I can get a signal, It is very noisy can any one suggest a good timebase/ setup for the probe as the automotive software doesn't have the option.
Thanks

Kuga can High/ Low

Hi, Can I have an opinion on the attached waveform, the Can High signal (red trace) goes down as far as 830mv in places, it is easily identifiable as the wave form has a sudden change in voltage, The car is a 2010 Kuga that is intermittently bringing on the power steering light, eml and anti skid li...

A4 abs sensor

I have a 2012 A4 that I am trying to check the lhr abs sensor on but for some reason I am struggling, unplugged it only has like 300mv on both wires and plugged in is the same, the trace is very noisy, I have tried various earths and I am now direct to the battery but nothing, I have tried the rhr a...

is220d slow to build fuel pressure

Can anyone tell me if you see anything wrong with the attached waveform, It if of the fuel rail pressure sensor which seams to take over 2 seconds to build full pressure and also the voltage and the current of the scv, the current seams high at over 2 amps most of the time, the test was done using t...
