Hi guys,

I have a problem with connecting diagnostic to the Felicia 1.3MPI 2000 year. I was missing one ground on the OBD connector, which I installed. But still no connection to the ECU or faulty codes. Anyone have any information which diagnostic to use or am I missing some pins at the OBD connector. On the picture the pin 5 missing ground is installed.

Thanks

This is helpful?

I have the power and diagnostic is trying to connect but at the end it says failed to connect. I used foxwell hand held reader. What does the signal ground means(pin 5)?

Thank you very much, this helps a lot. My next question is: So diagnostic should work only with pin 4, 7 and 16, or do I need to install pin 5(signal ground) and pin 15(K line-K2 and what diagnostic do you recommend? I currently have Foxwell NT 201 hand held and says failed to connect.

I have and OBD11 device just for simple scanning and code erasing, i am not car-electrician but @Thefeliciahacker has a VCDS programme and more experience on this matter.

@Thefeliciahacker can you help me?

Are you sure the Foxwell NT201 works on a European VWŠkoda Felicia 1.3MPI 2000 year, as 2000 is a threshold point. (Link I got say says free lifetime updates which might be good).

Current (?)Foxwell NT201 web link has 'Quick Start Guide' with pinout in it. - https://cdn.shopify.com/s/files/1/0581/4691/4470/files/Foxwell_NT201_User_Manual.pdf?v=1721296209

At that level the Foxwell is only going to give the basic generic info and code delete.

Sorry I've no idea about the wiring on/to the OBD port, I could guess but that's not a good idea with these sort of things.

When Thefeliciahaker is about he will probably be able to give you confirmed information. Good luck.

I saw someone here said that they used it and it connected to the car, I don't if it was European or American. That's what I need to read and delete the errors, but it looks like I would end up buying VCDS

I don't think the Felicia was ever sold in America so if you have bought the European version of the Foxwell that the other person had you should be fine you just need the wiring correct on your car.

I would wait and see when Thefeliciahacker arrives as even if you get or borrow a VCDS the OBD port will still need to be correctly wired for that to work and I am not sure how much extra the VCDS may be able to do on a 2000 Felicia though it may be a lot, you could perhaps research on old threads here.

Škoda Auto

Area served

Worldwide (except Japan, US and Canada)

Yes, unlike the UK which lets car manufacturers get away with lots the Yanks sue as VW found out when fiddling and cheating the diesel figures, hence their subsequent rush into EVs and Chinese market, that's (not) going so well. Of course the very highly paid bosses at the top still keep their jobs, enormous bonuses and enormous pay-offs and pensions so they did learn from USA corporate bosses.

It should self-identify the protocol used.

Tried it several times, every time it says failed to connect. I took the installation/wires out to check it for the right wiring or any breaks.

I may be wrong but this is how I understand it -

• Felicia 1.3MPI 2000 year, was missing one ground on the OBD connector, now I installed but still no connection to the ECU or faulty codes

• (pin wiring diagrams to OBD port as in previous posts)

• pins 4, 7 and 16 wired

- are pin 5 (signal ground) and pin 15 (K line-K2) also required to get the Foxwell NT 201 to work successfully?

HTH.

Yes, that's correct. I took the wiring out from the car to check for wire conductivity and if it's everything plugged like it's supposed to

My 1997 Felicia used KWP200. a specific protocol that most cheaper and easily available OBD scanners don't use, because it was only used in very few types of car.. ☹️

I did eventually find a local Auto electrician who's £1000 code reader did work, and he showed me that fact.

So it might be that your code reader will not work.

Earlier years were a bit of a wild west, well east for Europe comparted to USA, different systems and leads/plugs/sockets but with the standard 16-pin "port" socket and plug things are usually sorted by the modern machines as long the appropriate program for the make, model and year of car is on the machine and it'll get generic basic stuff. How much that actually tells you is a different matter, sometimes just stating the "bleedin' obvious" but that could be conformation perhaps.

We pay well over the odds for all machines compared to USA, bigger market I expect.

The KWP 2000 protocol uses a physical layer, identical to ISO 9141-2, for bidirectional serial communication over K-line with the controller.

Some modern OBDII scanners they don't support the Felicia's ISO14230 (KWP2000) protocol which uses for communication between ECU,sensors and OBD socket.

Here is one that i tested and never-ever worked

because is an OBD II and we have OBDI (or plain OBD).

Also those cheap Chinese

also they do not work!

So @DemoVrh is the connections are the proper but the scanner does not work, you can not do anything about it.

I paid for 2 and lost money and time-effort, the OBD11 works (but has no fancy gauges on your smartphone) and the VCDS via laptop.

On cars going back this far (and newer/latest models) you do need to check the machine, which ever one, has the program on it for your car and that the program works, or works as much as you want or need.

Some makes and models of scanner may work better than others for your particular car, even within the same manufacturer's range of scanner models, all have errors and omissions. Those that do professional diagnostics may have several scan tools they use for various makes, models and years of cars, unless they rely on one and that will cost more than £1,000.

Do you mean OBDeleven? - https://obdeleven.com/features?Skoda

I have seen some members cautio about using some of the one-click features but I don't know if, or how much, this applies to OBDeleven but I doubt there is too much you can do on a 2000 Felicia.

Isn't there a factory workshop manual showing the wiring to the OBD port?

I never saw your post where the OBDeleven wasn't working, did you contact the supplier or OBDeleven about this as some users have developed One-click for Felicia models and OBDeleven claim Worldwide coverage (except China) for VAG Group. - https://obdeleven.com/supported-vehicles?Skoda

Perhaps a OBDeleven owner could have walked you through it's use - originally I never know how to use a PC because I didn't know it need to load up after being switched on, that took a good while back then, as I was only used to seeing, but not using, computers in big offices with monitors (VDU?) and keyboards off a central computer. If you are not told about the basics you can't progress. It's a bit like my wife navigating written instructions on a car tour, first thing I need to know is which exit to use and whether to turn left or right (or straight over) from that exit before starting the tour or that section, getting to the start, to start (and for a start).

I'm not a fan of anything on a "smart" (they are not) phone or device and prefer stand alone plug-in power from car scanners or ones you can transfer to a laptop for bigger screen and a keyboard (preferably on mains power not its battery) but an OBDeleven was used to 'code in' the battery for my wife's VWŠkoda Fabia and do a full report prior and it was good with those (I realise it's a different and later model).
