Airbag light only from passenger seat

[JeffK]

Hi All, I've got an intermittent air bag light that goes on and off while someone is moving around in the passenger seat. I inspected the wiring/connector and looks good but I'll replace the seat harness just in case I missed something, and it's not that expensive.

I read the code and confirmed it is the passenger seat, I'm not surprised.

Is there also a sensor in the seat to detect if someone is sitting there?

Edit: I have a 2012 regular cab ST

Haven't found any info about an occupancy sensor so these trucks probably don't use them. I'll be replacing the seat back air bag harness first this week. Seems when someone is leaning onto the seat back is when the light and ding goes on and off.

You can download a free pdf copy of the Ram manual/s ..do a search on this site. I bet the answer is in the SRS troubleshooting tree.....

Thanks. I'll see if I can find them.

Also worth noting ...I've had two vehicles in the past ..one Jeep, one GM, where the yellow SRS connectors didn't snap in like they should and eventually came loose. The connectors couldn't come apart, but were loose enough to fail the self-test. Since you bought a new harness, maybe you'll get lucky and that'll solve your issue. Let us know.

I'm pretty sure there's got to be an occupant switch ...because SRS systems these days are progressive (multi-stage) depending on the severity of an impact ... but I haven't specifically looked it up on Rams..

Will do. Harness is coming this week and should have installed next weekend.

Took the seat apart to install the new airbag harness. Definitely no occupancy sensor. The only wiring to my seat is the pair of wires for the air bag. Good news is no more light. I inspected and tested the old harness and couldn't find anything wrong with it, but glad it's fixed now for only $43 for the new harness.
