Air Bag Sensor Light Code 15., Solved! Options

[rapid36]

Hi i have a 94 celica ST and i have a code 15 coming from the air bag computer. I went here to see how to go about fixing this.

I made it to step 8 where it tells me to measure resistence. it said this "measure resistance between terminals +S and +A (less than one ohm)" Now when i did this i got 2.2 ohms on both front air bag sensors, Then it said to do this "+S and -S (infinite ohms)" I tried measuring it but my volt meter i dont think displays infinite (if someone knows how to measure this then please let me know). And so i skipped that one and then i went on to this one "-S and -A (755-885 ohms)" I got 816 on the driver side air bag sensor and 822 on the passenger side air bag sensor. So Do you think these air bag sensors are bad?? cause it said that it should be less than one ohm and i got 2.2 ohm on the first test. Please share your thoughts.

If you are reading a resistance of Infinity most modern meters will read O.L. for Open Load, means basically no connection.
From what I understand the airbag sensors are One-shot mechanisms, so for example, if the car had a minor, low-speed, punch in the nose it may have tripped the sensors and yet not been hard enough to set off the air-bags.
In that case you would need to replace the sensors. Also when trying to read a low resistance like 1 ohm check the range setting of the meter so that it is on it's lowest range and will give you a more accurate reading. like there may be one for 0-5 ohms, and another up to 10k ohms, and another up to 1M ohm. It's different with each meter.
