Help on a 2014 V70 135 "SRS Airbag Service Urgent"

I don't see any srs codes.

It shows multiple codes for "lost communication with srs module" that's why me and David E7 were leaning into checking that module first.

I think in Vida there should be information about how to locate the module(still think it will be below arm rest of the front seats). Find electrical diagram and check if the connector wires correspond to your diagram(colors, numbers). Then check the powers and grounds with load(through 2amp bulb, this way you will assure wire is capable to carry current and not just voltage). Make sure you are using tiny needle probes when front probing. You can easily spread pins with big leads.

I found the module with the green connector, but I couldn't take of the middle console because I cannot find a tutorial. Just the sideplate of the middleconsole and you can get the connector

there are youtube videos.

when you turn the key does the seatbelt chime warning sound ?
does it go away when you buckle the belt.

no warning sound of the seats

did it used to chime?
if no, see if the chime is turned off with vida.

Found this on quick search. Hopefully will help somewhat

Yes it used to chime when I was driving unbelted.

Thank you for the video, mine is a bit different tough but this helps too

Today I took out the seat and removed the seat belt pretensioner. The sensor is defective. It had no change in Ohms or electrical flow.
I made a bridge to simulate a closed seat belt and the SRS module is still showing of the same issue.

I ordered another seat belt pretensioner and maybe I will need a srs module. Can I just swap the modules or do I need to install programm it with vida?
Regards

With anything past 1998 it is safe bet that you will need to program the module. I think modules are close to $900 plus necessary instalation and programming. Before calling the module I would want to be absolutely certain the module has everything it needs to operate(meaning power(s), grounds(s), intact communication line(s)). You need to find electrical diagram in order to be certain you are not missing anything. Unless when you look at the module there are obvious signs of damage from corrosion, water intrusion, etc.
P.s. were you erasing old codes between rescan?

the srs has a limited number of resets, once it reaches the maximum resets it has to cleared.
heres a company in Lithuania.

Don't discard the original sensor, it might be needed to transfer data from the old to new.
this can be done remotely.

Yes, I've erased it but it still isn't turning yellow.
I wait for a replacement belt lock pretensioner since I thought this may be the problem. It showed something above 3 Megaohms on my multimeter
