It did seem kinda odd that the cable deteriorated in the middle of a full length with no other real wear spots so I kinda suspect that maybe a grain of sand or salt or something fairly rough must have got in there and proceeded to grind a hole in the cabling as I turned my steering wheel day after day. I did though put a layer of dielectric grease on the ribbon cable just because I did see a tiny bit of it on the cable when I had a closer look at it. I didn't put any tape there and quite honestly I'm not expecting another 200,000 from the fix but we'll see what happens. I should first say thanks for all of your postings Scott, they really made it obvious what I was after. So the car went back together a lot easier than it came apart. The remaining wire was cut away after the pic was taken. I figured that I had nothing to lose to just solder it up along with a strand of thin copper wire embeded in the solder job. The culprit is the white ribbon cable seen here, as expected.Ī closer look at the ribbon cable (spiral cable) reveals a worn strand in the cable which has created an open circuit. Here are some pictures to go along with the fix.Īs you can see the Airbag light is on as well as the engine light, which I had just acquired in the last few days, probably gas cap or something?Īctually I was hoping somebody could tell me where to look in this picture for the 2 points for reading the codes.

So I have a 2007 Yaris but could not find the service manual or even where to short the pins for a code read but the problem sounded just like the typical spiral cable thing. I had been driving around wityh this problem for about a year now and decided to fix it with the help of your handy forum here. You have to pull the center console to gain access to the connector on the SRS ECU. So, you can leave that connector plugged in and check for no opens or shorts all the way back to the SRS ECU (which is located under the bottom of the center of the dash). On the steering column end of the spiral cable when you pull the connector off the pins short together. The driver's side airbag has two squibs, hence the two connectors. Squib is just a fancy name for the explosive portion of the airbag. Are these connectors should NOT have their pins shorted? Should I investigate and remedy the short within these connectors? But it didnt make sense as to why would Toyota use different wire but short them.
Since both the Black connector and Orange connector's had their pins shorted, I thought I must be by design. What was more interesting was that each pin had different color wires associated with it. What was interesting to me was that each connector had two pins, these stupid pins were shorted together. There was an Orange connector and a black connector. When I took the airbag out, I removed two connectors from it. With the spiral cable, when the connector is unplugged the two sets of squib pins do short together. Thank you.ĥ1 can indicate a short or an open in the driver's side squib circuit. Is this correct? Should the pins be shortaged? Anyways, when i assembled the airbag, after a few minutes, the SRS light came back on. When I used the DMM to see for shorts or open connections, I noticed that the two-pin of each connect, orange and black, were shorted together. However, there are two connector going to actual steering wheel airbag. The robin cable did not have any damages or breakage. So, I removed it and took to the lab and used DMM and microscope to see if anything was damaged or shorted. I am keep getting 51 51 51.I had monitored it for a few mintues to see if there's any other code aside from 51, but no. I followed Scott's write up, by the way thank you it was very helpful, I used the ODB2 jumper trick.

There are numerous other things that could cause your light to be on, but with the error code, the flowchart, and a lot of patience, you can certainly solve it yourself.īy the way, the service manual is an invaluable resource for any kind of mods or repairs.

Saved myself $250 over a pro repair :smile: But after this happened, I took it all apart, and was lucky enough to find a spiral cable assembly in a junkyard, soldered it in, and my airbag light has been off for several months now.
Don't ask me how it broke I've never even thought about taking off the wheel. I eventually traced it down to the spiral cable in the steering wheel. From there, I looked up the code in the official service manual, and followed the flowchart to find the problem. I did the old "OBDII port jumper" trick and found the trouble code.
