I find that most American and Japanese(except Nissan) cars will reset on their own if someone turned the key on by mistake. German cars a big no no. I would say you have a wiring issue. I know that your checked your wiring under the seat but maybe you have a pinched or disconnected wire at the bag.

I will go through them again, my research today says the same.

I'm a certified tech at a dodge dealership. The conectors tend to be sensitive to poor connections. Its common in those trucks especially with thr thorax inflators in the back seat sides. Double check all connections and unplug them and plug back in 1 at a time. Also when you turn the key on the modules self check the system and if it doesn't see an airbag issue it shuts the light off instsntly. So each connector you try, cycle the key

Thanks, all found a connector that looked good but was not. All fixed

We purchased a $100 OBD reader, it resets SRS lights for the models that don't reset themselves such as Mercedes. The best feature is that in a situation like this it will usually tell you what seat is tripping the light, this way you know exactly where to check for bad connections.

Thanks, Sonny I have been looking at them just for that reason. It would have saved me a ton of time.

We boa VR15. About $150. I’ll Mercedes and BMWs should use the 10 minute rule with regards to the battery on and off no Arabic lights will go on
