Airbag light on

Magically, all the Toyota dealers are booked solid for an SRS check, and it kind of terrifies me. I think they may try and tear the car to pieces.


Might be testing the alternator theory blind, but it makes sense, though. The light stays off when there is minimal electrical load (when first started) but comes on when accessories and such turn on. Then it'll tend click off when returned to idle with no accessories.

Just take care of the alternator issue. You know it is a problem and based on you not seeing SRS codes with the jumper and the blurb I posted above, the alternator output is definitely the issue with your SRS.

Just checked the output of the alternator via a quick test at autozone. It's at around 14.5V, which IIRC is on the high side (no audio equipment on, and no cooling fan running). Increase of revs brings no change in voltage. I checked the codes again; light resets itself (and is no longer on). I think this thing is playing tag, and the voltage regulator is deciding to work every now and again.

Autozone guy says everything is "fine" but what does he know? Something awry here.



I still have an appointment with the Toyota dealer to get an SRS scan, but I have a feeling they aren't going to listen to me and simply take the car apart then try and charge me for something mundane.
