SRS Light Lights up during hot days

[Creatve]

My SRS light seems to be coming on intermittently during hot days(90+ degrees f). I wonder if the heat has anything to do with it lighting up. I got the codes read off a Mac Tools ABS/Airbag reader and come up with 2 codes.

B1869 - Air Bag Indicator Inoperative
B1994 - Driver Air Bag Resistance High.

Wondering if you guys had any ideas what needs to be done to fix these 2 error codes cause I have no idea what they mean :scratch:
Thanks

Was it ever in a crash? Is the battery or alternator voltage low?

Na its never been in a collision and the alternator is still charging (13.3-13.5v) and its still the original! I just want to get this problem solved so I dont have any worries wondering if my airbags will deploy if I get into an accident.

The SRS light blinked about 4-6 times within last year and yesterday its been the 1st time this year so its intermittent.

Low voltage to the system is one of many possibilities. Check the fuse for corrosion on the leads and I'll do a little research. Since it is an intermitant problem the measurments have to be taken when the light is on. I wouldn't use the meter directly on any of the SRS componants though just to be safe.

I checked the fuse and the contacts were clean. I also scanned the code while the SRS light was on and now its just mentioning the B1994 code. I had my alternator load tested and it tested good. Still dont know what could be causing this problem

My understanding is that the air bags have a certain resistance that the computer module sees present under normal conditions. If that resistance isn't present or for some reason the supply voltage isn't correct then that can cause the trouble light. I'll be honest. Since I haven't run into this problem yet, I don't want to risk giving advise that might trigger the air bags.

My opinion is to take it to a qualified technician and put the liability on them. If that airbag goes off in your face while you are driving, it may be ugly. If you attempt to probe the electronics with a meter you could loose an eye.

I wish I could have been more help but your life is more important at this point.
