Airbag light won't turn off

[transcendentalcrap]

Well after a bit of research, I found this thread and thought I'd add to it rather than start a new one.

My airbag light came on Friday while driving down the highway. What I have so far is a 51 code. I looked up the service manual and got the four possible problems:

1. Instrument Panel Wire
2. Spiral Cable
3. Speed Pad (Drivers Side Squib)
4. Center Airbag Sensor Assembly

I don't know if I'm tired from work or what but right now, I don't know what to do next. The manual is not making sense. . .

51 Is an issue with the driver's side squib circuit, so basically it is something in the wiring between the SRS ECU and the airbag. The most likely culprit is the spiral cable, so I would start by testing continuity between the squib connectors (with them disconnected) and the D3 connector on the steering column.

Thanks CTScott! I was tired--I put the manual reference page into the pdf file thinking that would be the right page. Doh!


The yaris met a white tail deer about 10 months ago; and since the repair I've had no problems until this past weekend. Off to buy a multimeter . . .

I'm now having this same problem on my '08 Hatchback. I'm getting a 3251 code. Could you elaborate a little more on where the squib connectors are, how to disconnect them, and the location of the D3 connector on the steering column? Is there are wiring diagram for this connection? Thanks in advance, Tom.

To get to the squib connectors, you have to remove the airbag from the steering wheel. The D3 connector is under the lower steering column cover. The actual airbag connector is the yellow one (D18) next to D3.

The SRS section of the service manual shows how to get to both and has the wiring diagrams.
