Airbag light: code 8- firing circuit, side airbag, rear right side
 
After I changed the regulator on rear right window, the air bag light came on. This was the second regulator I changed. The code from B800 scanner was 8, table 10 which points to firing circuit of the rear right side. After I reset it, it came back the next time the key was turned on. I check the connector and one of the outside legs having locking hook was broken; however, the legs that push the shorting circuit were good. When I put the lock piece down, the resistor measure between 2 wires was 0. When I lifted the locking piece up, the resistance was 2.2 ohm. The connector seems to work fine and I think the outside locking leg did not cause the problem. I exchanged the airbag with a different one from other window (a 3rd regulator broken I changed after this one), it still showed the same code.
What else should I checked. I read forum mentioning about lock spring on other car but i cannot find one for this car even from part diagram.

Clockspring is for the steering wheel airbag. There are no clocksprings in the curtain airbag or passenger side air bag.

If clocksping is for only one airbag, then I am not sure what's problem is.

Problem is that you didn't disconnect the battery when you played around with the SRS system.

I understood that but I am looking for a way to fix it.

so how do you reset the SRS system if the battery was not disconnected initially ?

If you already reset the SRS but it keeps comping back, you need to find out the code that is triggering the SRS and repair the fault.
