Hi guys, new to the forum. I'm having the same problem and I did the jumper wire trick an came out with codes 32 and 51. Any idea what code 32 is? Btw, I couldnt find the new member section to introduce myself. Thanks for the help

32 indicates an issue with the occupant classification system, which consists of the OC ECU (the black box under the front edge of the passenger seat) and the 4 sensors in the seat frame for measuring the passenger's weight.

Hello! Im new in the forum, my mother in law yaris went in a light rear accident recently. Now the passenger airbag light always is in off. No matter somebody seated or buckle up. i read this thread and i understood what to do. But i have a problem. I cant download the service manual from the link provided. Only i need to know what pin is TC and what pin is CG physical in the obd 2 conector to make the jumper. Thanks for the help!

See post #2 of this thread.

Hello scott! i went to post#2 and i found only a link. When i hit this link i cant find nothing about how to find TC and CG pins in the obd 2 conector. I apreciated if you can tell me directly to me how to find those pins in the obd conector. I checked the obd conector in the car and i dont found any pin number or letters in the conector. Thanks

I have a 2007 Yaris coupe. The srs light keeps turning on and off. I followed Scott's write up, by the way thank you it was very helpful, I used the ODB2 jumper trick. 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 thought it was spiral cable. So, I removed it and took to the lab and used DMM and microscope to see if anything was damaged or shorted. The robin cable did not have any damages or breakage. However, there are two connector going to actual steering wheel airbag. There's an orange and a black connector. Each connector has two pins. 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. Is this correct? Should the pins be shortaged? Anyways, when i assembled the airbag, after a few minutes, the SRS light came back on. I am not sure what the cause is now. I would appreciate any timely response. Thank you.

51 can indicate a short or an open in the driver's side squib circuit. With the spiral cable, when the connector is unplugged the two sets of squib pins do short together.

r0m4ca3ped · 12-12-2012, 11:44 PM

Scott, appreciate the quick response. I do not understand what squib means. When I took the airbag out, I removed two connectors from it. There was an Orange connector and a black connector. What was interesting to me was that each connector had two pins, these stupid pins were shorted together. What was more interesting was that each pin had different color wires associated with it. Since both the Black connector and Orange connector's had their pins shorted, I thought I must be by design. But it didnt make sense as to why would Toyota use different wire but short them. Are these connectors should NOT have their pins shorted? Should I investigate and remedy the short within these connectors?

Squib is just a fancy name for the explosive portion of the airbag. The driver's side airbag has two squibs, hence the two connectors.

On the steering column end of the spiral cable when you pull the connector off the pins short together. 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). You have to pull the center console to gain access to the connector on the SRS ECU.

r0m4ca3ped · 12-12-2012, 11:46 PM

Okay, if one removes these connectors and if they short, and if the ribbon cable is free of any defects, what else could cause a code 51?

r0m4ca3ped · 12-13-2012, 01:14 AM

any ideas?

CTScott · 12-13-2012, 09:52 AM

Oh, and another thing - For testing the spiral cable, make sure that you do so with it in motion. It might require a second set of hands, but check for continuity while turning the steering wheel back and forth.

r0m4ca3ped · 12-13-2012, 01:24 PM

Thanks, I will double check the spiral cable today. So, I am keep getting code 51 in a pattern and this if for spiral cable. However, today when my friend whom weighs probably 120 LB sat in the passenger seat, the airbag was off the entire time. But when I dropped her off, the stupid srs light came back on. Is there another code that I am not seeing? Thank YOu

That is definitely odd. The codes relating to the passenger occupant classification system are all in the 30's.

r0m4ca3ped · 12-13-2012, 02:14 PM

I sat there for a while and read about 11 to 12 codes and they were all 51. I dont understand what to do now.

It might be worth having Toyota read it with the Techstream tool to see if there is better info available that way.

El Tomas · 03-25-2013, 10:01 PM

thanks CTScott
this post has been very helpful!!
fixed following instructions in post #2 of this thread
this is what it was:
Yaris 2008
car was involved in a light rear crash (broken bumper & tail light).
Airbag light ON, and passenger airbag OFF,

TOYOTA dealership wanted 108.00 dlls just to to pull out the codes,
and if possible another 80 dlls to delete the error codes, but they didn't guaranteed that by doing so would fix the problem

I pulled code 32 jumping terminals 4 & 13 on the OBD port
i changed this computer that is located right below the passenger seat.

voilà finally got the airbag light off!
I hope this info helps others save hundreds like i did
thanks!

My airbag light (not passenger light, but the red light in the dash) has been on since I cannot remember. I could care less as long as the car runs and has no other mechanical defects.
