Hello,

Yesterday I had my power steering rack replaced due to an oil leak. The airbag came on. Scanned it with my small OBD2, gave me: Airbag circuit resistance high, DTC B1031. Cleared the fault but it instantly comes back. I have doubts that the technician may accidentally cut some cable or sensor in the front. What to do and how to fix this?

Yes you are right the mechanic allowed the steering wheel to turn to many times now the clock spring behind the steering wheel needs to be replaced. Here is a guide to show you what you are in for when doing the job:

As you said the mechanic must have done bad job in respect of the power steering column and the clock-spring, he tied nothing, he marked nothing and apparently he knows nothing about airbag system and its relative electrics. The strange thing is that horn, radio and cruise controls are working fine, although lots of posts show otherwise.
One Suzuki Electrician I know, called him over phone (he is very far from my place and explained the whole situation, he said "you have to replace the airbag click-spring, the mechanic must have done a lot of hard twisting when they removed the old power-Steering rank", but that does not make sense to me as the Electrician who made the first diagnostic removed some plug and then scanned it one more time, gave him another DTC code in addition to B1031 (I guess it was B1035), by this result he confirmed nothing wrong with the clock-spring.
I do not know who to believe, but I know I will pay a lot if I go to Suzuki authorized workshop because they know nothing except replacing with expensive new parts besides their high wages. I am really confused.

The only way to be 100% sure is to test the wiring through the clock-spring. Here is a guide and the wiring diagram to confirm the issue:

Thanks a lot dear Ken for the valuable information. I cannot read diagrams myself but I will show it to the electrician and summarize your recommendations hoping all will guide him to locating the cause of the error.
Just in case I need to replace the clock-spring, from where I can order it online and how much is it?
Regards

That will be a dealer item I would say about $140.00 could be less though. You can rear the wiring diagrams like a road map. Just test the wires through the clockspring see if they are connected.
