I had a friend check the reason the Air Bag Light would not extinguish using a code reader. This code presented as an old trouble, he cleared it but the light illuminated again after driving a short distance(seemed to react to braking?) He put the code reader on a second time 2 days later and cleared it again(it still presented as an old trouble?) But this time the Air Bag light has not illuminated for 50+ miles so far?

Problem there is there is multiple connectors from SRSCM to the end at the squib. "IF" I had to venture a wild guess, the "clock spring" (Toyota calls it a spiral cable) between the squib and steering column might have an open circuit in the ribbon cable inside the housing...

This started @ about 62,000 shortly after the 60,000 service was done, does this light mean that the entire Air Bag system is inoperable? I'm of the understanding that the warranty coverage for this item ends @ 60,000 miles, do you know if this is correct, or is it possible it was extended? If it is not under warranty, would you venture an estimate for repair?(ballpark figure) "What is perceived as real, is real in it's consequence"

After last reset, it went on then off with around a sharp turn! I'm scheduled to have it replaced as soon as part is obtained by repair shop, should be this week, Thanks again "What is perceived as real, is real in it's consequence"

Posts: 56 (06/11/09 07:38:04) Reply Quote More My Recent Posts	sbr711, Thank you, Thank you, Thank you You hit it right on the head with your "wild guess" it was the perfect diagnosis for air bag code B-1346? And replacing the "CLOCK SPRING" was the perfect remedy for this problem! We just finished driving 1000+ miles from NY to FL and there was only the initial illumination @ Start-Ups after that the system worked fine. We had a mechanic/technician that is also a relative check the code & replace the "CLOCK SPRING" @ a reasonable cost. Thanks very much for your help, we really appreciate it!

When first turn key on, SRS light will illuminate, go out after moderate "6" count if all is well with its' self test. If it go out after test, then come back on, or is on while car running, there is a fault somewhere, and scan will reveal the fault code. Did you pop the cover on the old part and pull the ribbon out to see if you could find the break in the wire inside that ribbon ? Last Edited By: sbr711 06/11/09 08:14:28. Edited 1 times.

There are "6" wires in the ribbon "2" of which are heavier then the others, but no smoking gun among them? But the system is working fine now thanks to you!
