I have a code 222, open circuit in passenger airbag. I attempted to reset the codes using the code reader in the engine bay. Code won't clear. Took the car to my independent shop, he tested the circuit and stated it is the airbag. I got a used airbag, he installed that and the code remains, it will not clear. His suggestion is now take it to the dealer for testing. Closest dealer to me is 45 miles away, so it would be an all-day affair.

In the thread I linked to above, Henry noted that a drivers seat belt tensioner would also throw codes (very similar to the codes I'm getting), so would the passenger seat belt tensioner also cause a code 222? The passenger front seat belt is not retracting properly.

Possible coincidence, one of the motors in the passenger seat has quit, not sure if this is contributing to the SRS issue or not.

Any advice is appreciated!

 

Dealer. Sometimes they check the SRS system for free since it's a safety item.

 

Check your connections: there really aren't that many on a '93. Look up the SRS diagram to see exactly where they are...

I don't see how a belt tensioner can throw a code--it's not wired.

Seat motor will not throw a code either.

 

Seat belt tensioner would throw codes, IIRC about 5 different ones, but not the 222.

As you already know 222 points to the passenger air bag.

Seat motor is a searate circuit and separate bundle of wires from the airbag.

It sounds like you were in a accident? Did you replace ALL SRS components, incl Crash Sensor, clockspring, tensioners, airbags?

If yes, I would check one last time for 2 things: connector of Passenger airbag is properly connected and that you are doing the procedure correctly for erasing codes.

 

Thanks for all the information/replies.

Car has not been in an accident. It's my daily driver with about 180k miles on it. The SRS lamp came on about the same time as the forward/back seat motor dying, and finding the other thread indicating a possible link between the seat belt and the SRS lamp, I thought they might be related.

I attempted to reset the SRS light myself using the test A/B box under the hood, where I have successfully reset other CEL's in the past. I couldn't get this one to clear, so I had my shop check it out for me. He got the same code, 222, open circuit in passenger airbag, could not clear the code either, and diagnosed the airbag as the culprit. New is $800+ so I found a non-exploded/intact used one from an in-state salvage yard, and had the shop install it.

Airbag replaced successfully, code still will not clear, as per the shop. I will attempt another reset tomorrow, and pull the glovebox and look for wiring/connector issues.

 

Yes, there is a wire that goes to the tensionser. It basically triggers a plunger which tensions the seat belt. Maybe both wires (seat motor and tensioner) are pinched? It wouldn't be the first time. And SRS module is reading something wrong? The manual I have linked at the resources at the top is for 1994. Maybe 1993 had a different scheme.

Just be aware that if you play with the tensioners's wire, it may deploy the airbags. Just make sure to de-activate the SRS before playing with that wire. Follow the instructions in the Manual how to de-activate SRS. And no, disconnecting the battery is not enough.

 

I don't believe the 1993 960 has anything besides inertia type seat belt tensioners, so there is no current or wires.

BTW, how do you suppose to deactivate the SRS other than by disconnecting the battery? The recommended way is in fact to disconnect the battery and wait a few minutes for static electricity to dissipate.

 

I don't suppose anything. Read Volvo's instructions.

Lev: do you have any info on '93 SRS, which is specific to '93 and NOT '94?

I know that on 850s added SIPS in 1994, which although not part of SRS system, still is part of occupant crash protection.

 

SIPS in the early years has nothing to do with Airbags and such but only with force dissipation in case of a side impact, a structural design. Even my 1992 740 has SIPS but NOT tensioners, same as the '93 and '94s.

The Volvo instructions are exactly that: disconnect the battery, wait 30 minutes.

 

Of course it doesn't. I asked you if you have the '93 Wiring Diagrams / Manual.


'94 and later -- that's not the case. Go ahead read the manual linked at the top. And read the whole paragraph. I have deactivated SRS at my Volvos several times, sometimes I have disconnected the battery only, knowing I was taking the risk. Other times, I have done it the right way -- disconnected the connectors below the glove box.

Cases of accidental deployment are well known. It takes nothing to disconnect the color-coded connectors.

I doubt '93 was any different, which OP needs to know -- if there are no changes between 93 and 94 SRS, she can just use the '94 Manual.

 

Yeah, well, there is a big diff between the '93 and the '94 as the 94 was the first year of PASSENGER SIDE air bags.

And since this is in fact a '93, I guess we go by the pre 1994 instructions...

 

Then something's amiss -- OP says she replaced the passenger airbag in her '93.

 

Amiss, perhaps, but to clarify: my '93 960 wagon (the one in question in this thread) has a production date of Jan '93, my '93 960 sedan has a production date of Sept '92, taken from the manufacturer tag with the VIN on it in the door jamb. Both have passenger airbags.

Back on topic, have not had time to examine anything in the car, hopefully today or tomorrow I'll be removing the passenger seat to address the motor issue and with the improved room in the cabin, can then pursue the airbag and seatbelt tensioner wiring.

Thanks for the link to the srs wiring, I have downloaded that and will use it as a guide.

 

I guess the 960s got the bags earlier. My '93 940 has no pass. bag, my '94 does...
