    My 98 eclipse gst has the SRS light on and wont turn off.. after a lot of research i came to find out that it cant be done by tricking it anyway shape or form like those guys do on youtube to there mustangs and hondas. Would be nice but impossible with our cars unless you have a special tool obd2 that reads SRS codes.

    From the cheapest to the most expensive i have found to have this SRS light wiped by a dealer, i found the cheapest to be $30 to the most expensive at $738.00 including labor!!!!

    So after some more research i tried to think of other ways. Replacing the air bag sensors? According to the Haynes, Only the 95's have 2 air bag sensors. Every year on up, the sensor is within the Air Bag Module or air bag "ECU". I just ordered a OEM SRS Airbag "ecu" module. I'm hoping by replacing this will completely clear my SRS code and save me a ton of money. this ECU has identifying numbers on it MR243 890 on a yellow sticker. its a small metal box located under the arm rest.

    When i receive this i will safely install it and possibly do a write up so people like me can save money. i paid 14 dollars for this module on eBay from a oem guy selling parts. I already know to disconnect BOTH battery terminals and let the car sit for about 10-30 minutes before disconnecting anything SRS related. Wish me luck i will post the results! If this thread was unnecessary let me know. But since all the threads i found about this similar thing were from like 2004-2006-2009 i figured i would have an updated one and see if anyone has done this recently successfully!

    Wish me luck :hellyeah:

    I would love to not have to go to a dealer to clear my SRS light. Local one quoted me $50. Keep us updated.

    You can simply just unplug the SRS ecu under the center console armrest to rid this light, its a giant yellow plug

    Just a tip but if your horn and other stearing wheel items are not workin and your air bag light is on. Chances are that u need to replace your clock spring.

    and you have done this first hand? I found that once that sensor is engaged in the ecu it locks and the light comes on and doesnt go off, the only way to get it off is by a dealer with a tool or just get a fresh SRS ECU..

    its worth a try, but i think if it was that easy i would have found that issue cause im not the only one with this problem. we will see.

    my horn works. i thought that at first cause the horn didnt work but i could hear the relay clicking in the engine bay and i tested the wires where the horn plugs. Horn was just bad. went to a junk yard and couldnt find any on any dsms.. just a tip for yall if you didnt know.. older dodge neons have the same horn and will plug right up. :thumb:

    as for unplugging it wont cut it in my situation. i have to have my car inspected and part of the inspection is that my SRS light cycles on and then off when ignition is turned on.

    like i said my horn works now and so does all my switches and stuff in the steering wheel area. ill have an update i guess when i get this new SRS ecu

    So after a few short days i received my new SRS ECU! Disconnected the Batteries, waited about 20 minutes. Unplugged my old SRS ECU, with a 10mm socket undid the 4 nuts. pulled it off. bolted the new one down, plugged it in. Reconnected my batteries. turned on my ignition....7 seconds later BOOM NO MORE SRS LIGHT!! :hellyeah: :rocks: :hellyeah: :applause: :dsm:

    again i only paid 14 dollars for this new unit on eBay! some of you may ask why is he so worried about the srs light why dont he just unplug the ecu like one guy did here on my thread or just remove the bulb.. well i actually NEEDED to fix the issue. my car has a salvaged title. i dont know how bad the car was wreck in the past but who ever fixed it put it back together in pristine condition but didn't bother to re do the SRS ECU. In order for me to get a new title for my car is to have a rebuilt title inspection. One of the automatic fail checks is that your SRS light cycles on with ignition and then cycles off! that SRS light was the only issue holding me back from registering my car!! :thumb:

    now i cant promise you that this will fix the problem with you guys who took out your airbags and reinstalled them or removed your dash etc etc.. but it doesnt hurt to try what i just did for only 14 dollars! compared to the amounts i listed above. you may even find one cheaper at a junk yard. but keep in mind why those cars are potentially IN THE JUNK YARD! It makes sense that this will fix your problem for you all who have SRS light issues with no accidents at all. Its definitely worth a try!! :thumb:

    here is one for 14.99 on eBay

    96-99 Eclipse Spyder Air Bag Airbag Computer ECU 97 98 | eBay

    this ad has a or best offer link too. the one i bought, the guy originally posted it for 18 bucks. LOL i offered 10, he met me half way with 14.. still cheaper than the stealerships 600+

    any style eclipse rs gs gst gsx SRS unit will work 96 and up! 95 is the only 2 g with a different SRS ecu. the 95s also had the actual sensor in the bumper. 96 and up have the "g-sensor" in the ECU itself

    Wonder if there's a way to pull codes using a smart phone, or clear it without a scanner. I found this:
    Android SRS-Airbag Code Encyclopedia App for Samsung, HTC, Motorola | XYO

    Anyone know if some app like that will tell you what you need to do to fix it? I might just buy one of those ECU's on eBay to fix mine too. But I'd like to know for sure that it will actually fix it. I bought the car with the light on, just figured the guy before me screwed something up when he was trying to wire in the turbo timer.

    You can use the Torque application to check and clear codes as well as do some other logging and whatnot, but it requires a Bluetooth ODB2 adapter and the app can only be used with OBD2.

    The SRS ECU I bought and installed didn't clear the SRS light... just my luck.
