does anyone know how to reset the airbag warning light on a 93 ls400? any info would be great. thanks.

 

I had the same problem and took my LS (1990) to a local garage where they work on Lexus quite a bit. They tried conventional methods but couldn't reset it. Then I found this info posted elsewhere in this forum. I tried it & it Worked like a charm!

I modified the info a bit to help clarify some of the steps:

1. Make two jump wires, each about three feet long. 18 gage, insulated, solid copper (doorbell wire) works best for this procedure. Strip about 1/4" of insulation at each end of both wires.
2. Find the OBDI connector (it's in the center of the engine bay next to the intake)
3. Open it up and find AB & TC sockets.
4. Plug a jump wire into each socket. I don't know whether it matters but I was careful to keep the other ends of the wires from touching other stuff--or each other--at this point.
5. Now, touch the other ends of the wires (one wire at a time) to the negative battery terminal, alternating TC, AB, TC, AB at about one second intervals.
6. Continue for about 7-10 seconds.

Note: This worked for me on the first try. I am told that if it doesn't work, try either speeding up or slowing down the TC, AB, TC, routine.

While I did this, I had my son stand outside the drivers side door with the window up (I was a little concerned that the airbag might deploy!) and observe what was happening on the instrument panel. He said the airbag light began to flash; slow at first, then faster and faster until it went out.

Good luck!

Did this this afternoon. Worked great.

 

What would the procedure be for a 97LS side airbag light?
