2013 Suburban LTZ Service Air Bag, DTC B0021 Symptom 03

[George B]

Got an air bag light and "Service Air Bag" on my 2013 suburban. It was pretty solid every key cycle for a couple days. Yesterday it was flashing the light and kept coming up on the DIC and then stopped with the light and the message. Didn't set the code since about 14:00 Hours yesterday.

Checking the code indicates DTC B0021 symptom 0D. Says " Passenger Seat Side Air Bag Deployment Loop Resistance Above Threshold". Going to check the connector but otherwise don't know what to look at next. High resistance should mean a poor connection. Anyone got any troubleshooting guides?

I think this is the recall out that GM finally has the fix for. I get the 'Service Airbag' every once in awhile, I just reach down next to the console and passenger seat and jiggle the wire connector around and the warning goes away.

The connector for mine is near the back of the seat on the floor to the outside

Hmmm.. maybe GM changed it, I have an 09 LTZ and the airbag connector is mid seat next to the console. I have another connector near the back of the seat in the floor to the outside too, but that is for the heat/cooled functions and the movement of the seat

Airbag connector is yellow and orange right?

Airbag connector is yellow and orange right?

Yes, yellow for sure. I would check the connectors, might just need to unplug them and plug them back in.

The recall is dash airbags, at least on mine. Just had it done.

Done. Also looked at the data display for the system. Both right and left seats currently indicate the same resistance. Can’t fix what ain’t broke.

Did they break your dash and offer to replace it?! I'm just kidding. Haha

If only. I had already replaced it. Now if they had broken the new one…

2009 Tahoe I have the service air bag message and a red airbag icon on the dash. My Innova code reader picks up nothing. I stopped by Oreilly and theirs could not read anything either.
Question: what are you guys using to pull the SRS codes??
