Service airbag light came on?

[JML07denali]

My light came on out of nowhere and it's on a 2007 Yukon Denali. Where should I start to diagnose? Any help is appreciated.

Front sensors under the splash shield in the front. They are a bit pricey but it solved my air bag light problem.

There are two types of sensors make sure you get the correct one.

How much did you pay?

Re-seat the wiring harnesses under your seats first. If that doesn't resolve it, start your diagnostics with a Tech2 and narrow it down. You're dealing with yards of wire loom between the sensors.

Around $90 a sensor

But check the wiring harness under the driver seat first near the center console like mentioned above.

Is the airbag harness under the driver seat or the passenger seat?

Under the passenger for sure. Someone on here should have the schematic. I can't remember if the side impact also routes under the driver. Any luck with a tech 2? The dealer can pull the specific location of failure... For $100 unless you're a schmoozer

I'm going to try reseating the harnesse first. I called the dealership they said there is a recall on this but GM hasn't yet released a fix?
