I have a 2007 RX400h. All of a sudden I see the air bag light on the dash and the passenger air bag off light always lit. It does not matter whether I am sitting in the passenger seat or not. I should easily weigh enough to turn on the passenger air bag. Is there a way to view the error code and/or reset the error code? I have a basic OBDII scan tool. It does not show any error codes. Any ideas?

Thanks.

I noticed that when the passenger removes the seat belt, the seat belt light does not illuminate, but it does for the driver. Do I assume the problem is with the passenger weight sensor?

I had to have the seat SRS sensor recalibrated. It cost me $150. That sounds very expensive for just hooking the car to a computer.

that does sound a bit steep for calibrating a sensor. My first guess would have been that the cabling under the passenger seat came unplugged.

I bought a Toyota/Lexus cable that connects to the car and to a computer using USB on ebay. It worked great. The dealer went on and on that it could take 2 hours to do the job. I did the whole calibration in maybe 20 minutes without ever having done it before.

Do you have airbags in general?

User 122922

good question, the car is clean title and I’m pretty positive there’s an airbag yes in the car!!! Any suggestions?

Is there anything at all on the passenger seat? It takes only a few pounds to make the light go on.
In fact, I have a habit of resting my right hand on the passenger seat while going around corners and light will go on.

but my case is different I have it off at all the time no


matter anyone sets in the passenger or not

All I can suggest is using Techstream to see the current command settings.

btw, I didn't know 2007 400H's had that type of center console -- it's a little different from all the other RX's. Is your car from overseas?

1. Look at passenger seat bolts. Maybe it was removed for some reason from car (or replaced)
2. Check all wire connectors under the seat.
3. Visit O'Reilly store to reed errors for free. It will show you where to search.

did you managed to fix the issue? Coz I got same too

I took it to a Lexus specialist and he did a diagnostic and couldn’t clear the code and couldn’t recalibrate also , so he told me it might be a bad sensor ? Since then I haven’t really bothered.
