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.

Thanks! Unfortunately the guy lied to me and he doesn't know what he is doing when modding a car so there is just a ton of chopped wires behind the dash. Its very frustrating. So i will be posting a lot on here on the forums to try and figure everything out and where they go to. I had the battery connected but the connector going to the air bag computer was disconnected when doing all of the checks. I will disconnect the power and then flip on the lights to drain it (good tip). However this wont effect my tests because the connector on the front air bag sensor has to be disconnected completely to check the resistance. I wouldn't be surprised if the previous owner cut wires from the air bag system. I replaced the air bag computer but still have code 15. So the computer seems to be working right. I looked at the yellow wiring loom and it looks to be fine. However he may of done something weird with the wiring or maybe something legitemently went out in the system.
