Dear Experts ,

I am trying to analyse the basics checks of AIrbag issue ( will NOT use any multimeter ) so trying to see if all wiring is intact and no loose connection. Can anybody please advice if I am missing anything as I am seeing only just 1 airbag connector under seat rest 2 connectors as mentioned in video is missing even though same bracket exists as shown in video , also please advice I also don't see any extra cable connecting to ground terminal of my fabia mk2 . Any idea wht is the role of this wire ?

Thanks

Hi Experts , Can somebody Please correct me if my understanding is incorrect , I have found that other two types of connecter supplying power to heat the car seat and 2nd airbag, I believe my car does not have the both so I think of 3 plugs connector may be just for needed which is present .

I have reared 7zip website for information.

thanks

kind regrds

You have standard seats so you see only the yellow connector that is for the airbag in the side of the seats.

Also the connector you have seen in the video are different in 2011 models onwards, those are tipically only in prefaceift mk2 fabia

Appreciate @Jack25 for your quick response, so it mean mechanic had applied cheapest option as thought so It means the connector or wire has been changed hope it is fixed correctly will test with resister and update.

I have also found the seat belt tensioner was hardwired very poorly with ordinary plastic tape no wonder why it was throwing high resistance, the seat belt tensioner was from Skoda Passat .

Still unearthing slowly wonders as hobby project in car. Please can you dm me your VCDS diagnostics if possible want to check if all modules OEM number are correct so far I have verified with docs found on 7zap.com and feel that they looks ok to me.

Once again appreciate your time and support .

Kind Regards

My seatbelt are the one in the picture

The problem on the module is that the only one that is the airbag one and the instrument cluster; in this days I’m doing the retrofit of the climatronic and also the ecu is tuned, as long as you have a 1.2 tsi cbza with the exact same configuration I can gave you my coding but if you have like curtains airbag is a completely different coding because I don’t have that.

Appreciate Jack for your time , Mine fabia is CBZB 1.2 tsi tech (14 manufacturing year) , as per 7ZAP seatbelt tensioner for my car expects 5J (2)8 80202C which is may be specific for fabia 2014 and onwards model, the main point is resistance range of these tensioners, I have looked AI tool (AI cannot be trusted) found that 5J (0)8 80202(A,B, C) and 5J (2)8 80202C MAY not be interchangeable,, The 5J (0)8 80202 in generic part and fits in every fabia/Roomster model . Certinly prefix A, B, C does not effect resistance value but AESTHETIC improvement on connectors or plastic covering.

Whenever possible please do share your vcds coding it will be interesting to know how much things are same or different for both flavours of fabia. you my share any previous scan done I am more interesting for module OEM numbers. I have checked modules OEM number and matched with 7zap and found 99% looks fine only worry I have possible for airbag module controller which is doubtful 90% positive 10% negative.

I am progressing very well hope to complete this project and share knowledge with everybody .

I think airbag handling is not that challenging as presented on net , it is not rocket science just make sure to disconnect battery terminal for good hours for 100% discharging the energy storing capacitors . They cannot store energy more than few minutes but just be safe side I started touching airbags after 24 hours of battery disconnection .

Soon will be Testing ECU airbag wiring ( WITHOUT airbags connection simulating AIRBAGS with resistor ) will be done using 1 ohm , 2-3 ohm and 5-10ohm resistor to see the behaviour of ECU for low resistance, high resistance and just correct resistance. This will give me confirmation that airbag wring is prefect which seems to be good anyway and then will fit first set belt tensioner and test it , if all goes good focus will be front passenger AIRbag .

I will NEVER use multimeter for AIR BAG related wiring or on AIrBAG for sure .

Learning new things is great fun .

Thanks

kind regards

The OEM number as attached for my model of car , hope I am correct in identifying this

Chat GPT : Are 5J0857701 and 5J2857701 interchangeable?

No. They fit different mirror housings and different model years. Even though both are LED indicators, the shape, connector orientation, and mounting tabs differ.

If your concern is:

• Hyper‑flash

• Bulb‑out warnings

• LED load differences

…then both units draw similar low LED current, and neither will solve or cause those issues by “resistance.”

Dear @Jack25 , You were right , my car config is pre facelift possibly I was looking at wrong place of OEM parts info , today spoken to SKODA and they have reluctantly confirmed about OEM number of set belt tensioner , Bought it already fortunately I have bought latest Seat belt ending WITH 'D'

Once again thank you such your timely help .

Stay blessed.
