Uh-oh, It's another OBD turbocharger.

Or.. you could incorporate the flux capacitor from the previous night-light video and transform your car into a working time machine.. Unless of course it's the Lada, which isn't capable of reaching 88 mph

What about an OBD module that actually monitors the busses. analyses your driving habits, taps into phone's bluetooth and shames you by posting how rubbishy your driving is directly to all your friends' Facebook timelines

There's a certain pleasure to engineering quack products. Like a magician creating a convincing illusion.

Sometimes when you shunt or jam a network the ECU loses sight of sensors as you describe and goes into limp-home mode.

At least on my car (Ford, 2010 model), there are at least 3 networks. High speed, medium speed, and a speciality one for the airbag/stability control modules that isn't exposed on the diagnostic port. Found that indeed messing up one of the networks does affect how the engine runs, I assume because it loses some key sensor data and then reverts to a basic "it'll run but like a tractor" map. Had some fun playing with the canbus modules though and interesting to find how to interact and read data off. The canbus wires don't like being shorted together either :P <a href="https://www.ebay.co.uk/itm/MCP2551/162281092785" rel="nofollow noopener" target="_blank">https://www.ebay.co.uk/itm/MCP2551/162281092785</a>

I'd guess it may also be going to the other switch pad.

If you buy ten you get a free motorised toilet brush.

Power Prog sounds like a musical genre.

Good idea. I like the little round "ohm-box" to quickly use a resistor. @BigClive: where are these to buy? I could use one of them!!

That's what I love about you Clive, you're such a glass 3/4 full sort of guy. Not only do you rate the pros and cons of their 'fraud pulling' devices but you make suggestions for improvement and cost saving, always the engineer over everything else! 😁

In the US, 1996, most cars had it in other markets by 2002 IIRC. The nice thing about OBD however, is if you get a proper reader and software, you can basically interrogate and investigate *every* module on the car. IE I've got an E46 BMW 3 series, and with a £20 adapter and a laptop I can see what's going on with the ABS module, SRS modules, body control module - and I can perform limited programming. The one touch 'rise' on the passenger side window, for example, was disabled from the factory. I turned it back on and felt much better for it, as that has been annoying the utter piss out of me since I bought the car!

Just a thought ......how about a video on your tool box....eg...type of test instruments you use , how to use , cost effectiveness , etc....we often see you drag things into the video filming area to test projects , and l have personally bought a couple of the same test equipment you have used....

In what year did the automotive industry move to things such as canbus etc? Nowadays there are so many points of faillure in cars. Sometimes you can't even change a defect headlight lamp without ripping the radiator out :(

Where does the 5v go under the "S1" print? It T's to pin 2 and something under the switch... doesn't make sense on that layout.

The black dot probably means it failed quality control and was therefore available to sell on ebay. The quality fake items are reserved for better markets.
