Hi, I have the SRS light on for quite some time now. I got the vehicle scanned and the following code were retrieved: F4-11 and 22-10. The car was not in an accident. Light came on suddenly.

Any suggestions to fix the problem?

Thanks,

Russ

Hi,

I attached the detail about these codes. The vehicle does not have to be in an accident for the seat tensioner to activate. It could have just been a quick stop or even just a malfunction in the tensioner. This is part of the seat belt buckle and the only way to fix it is to replace it if in fact it deployed. They are a one use only.

However, I would strongly suggest having someone qualified check this out because if there is a greater issue with the wiring or something else, this could cause injury in an accident by not operating properly.

Please let me know if you have any questions. Thanks

Thanks for your response and helpful information Kasekenny1. I forgot to mention my car is a couple if it makes any difference. I have a few questions.

Are you referring to the buckle being a one time use or the seat belt? If the seat belt tensioner is deployed would the seat belt be locked and not retract? The buckle in my car does not appear to have a tensioner but the seat belt assembly does have a tensioner. I took the seat belt assembly off today to take a look at it to see if there was any issues with connectors being loose or off but all seemed fine. During this I read a sticker on the seat belt assembly saying it has explosive contents. I also took the seat out and checked for a tensioner on the buckle but it doesn't have one at lease not that I can see. Buckle is attached to a metal bracket attaching to the seat. Didn't see any cartridge tube that could indicate a tensioner.

I'm a little confused about the seat belt being bad because it's still operational as in it it's not locked and it retracts and also locks if pulled abruptly. I think it's either a malfunction in the tensioner or maybe something in the wiring/harness as you mentioned. I'll try to test the harness and seat belt per your attached instruction. Just have to figure if I can test it without the tools noted in the attachments.

Thanks again for your help on this.

Best wishes,

Russ

Okay. You are confusing the seat belt retractor and the tensioner. The tensioner on your vehicle is part of the retractor of the seat belt reel.

You are correct that if it deploys the seat belt would not retract. So it probably did not actually deploy but has an open circuit and so the control module thinks it deployed. This is how it tells if there is an issue in the system or if it deployed, is there is an open circuit.

Follow those tests and I am sure you will find your issue but more than likely you will need to replace the seat belt. If so, I attached the procedure here.

Thank you so much for explaining this. I was able to test the seat belt pretensioner for resistance and got a reading of 2.7 ohms (should be between 2-3ohms). I did this test from the seat belt only not at the srs connector terminal. Now that I reinstalled the seat belt and the seat I will test for the ohms at the terminal. I figured out a way to short the circuit without the specialty tool. I'll let you know how that goes. I'm thinking it's either the SRS floor harness or the SRS unit itself that's the problem. If the resistance between pin 14 and 15 reads 2-3ohms I'll start looking for a new SRS unit. If it doesn't read that I'll have to change the harness which would be beyond my capacity. If I replace the SRS will I need to program it to the car? I hear it won't be plug and play.

Thanks again for all your help. Really appreciate it.

Sounds great. I attached all the documents that I think you will need to calibrate and relearn the entire system if you have to replace this.
