Recently purchased a 1994 Integra LS (OBDI) with only 79K on it. What a find! (I bought my ’99 GSR with 78K on it and it currently has 265K and running strong!) The LS runs great, but the ABS and the SRS lights are on. The ABS, I was able to get the code for and it’s a 4-4, right rear sensor. I took that apart and cleaned it and re-installed it. The ABS light will go off after a few seconds after starting, but once you head down the road, it comes back on. Not sure what else can be done on that. Thoughts?? That’s the minor of my issues.
The SRS light will NOT go off. I’ve tried pulling the SRS DTC’s with the 2 pin service connector by the passenger kick panel, but the SRS light doesn’t even flash. I’ve tried resetting the SRS light with the 2 pin Memory Erase Signal (MES) connector and a paper clip. No dice. I can’t even perform the whole procedure because the SRS light never goes out for me to remove the paper clip, etc. I’ve disconnected the battery and let it sit to reset the ECU. SRS light still comes on.
Since I am second or maybe third owner on this car, I don’t know all of the history. The car does have very minor front right bumper damage. The seller said that someone backed into it in a parking lot. The air bags have not been deployed.
Is there something possibly not connected? Still has the original steering wheel and the horn works. Are there some hard codes on the SRS system that won’t reset? Do I need to get another SRS main unit? How else can I determine why the SRS light is coming on? Any other scan tools out there?
As always, I appreciate the collective brain trust here on ETCG. I’ve already looked through the 193 search results by typing in SRS. Any help you good folks could give me would be amazing.
Update: I noticed when I took off the speed sensor on the right rear that the “gear” or “teeth” that the sensor senses was pretty rusty looking. Would that cause the sensor to not count the teeth correctly? Because at low speeds, the ABS light stays off. Also, if I did get a replacement sensor for the right rear, is the sensor the same for 94-01? Was thinking junk yard.

For the ABS sensor i would just replace it if it has damage. you can’t really fix those since there sealed and are a unit. So check the wiring first to the sensor and if its good then i would just replace the sensor and clear the code. Now for the SRS unit you might need a scanner that can read SRS codes and see what it says.
Thanks NightHawk92. I found a used, known-good, replacement sensor online and replaced that today. It worked! The ABS light goes off after starting the car and doesn’t come back on.
Side note: I was working on a few other little things on the car and wanted to post this somewhere because I was astounded. So, the interior light wasn’t working. I bought a replacement bulb, but when I took the cover off, the bulb wasn’t blown. So, I checked the fuse. Sure enough, it was blown. New fuse, interior light now working. This fuse also fixed the following:
* Rear defrost button and operation
* Key in, door open chime
* Lights left on, car off chime
* Door open alert dash light (this light stayed on even with both doors securely closed)This reminded me of when my speedo went on my ’99 GSR. Coincidentally (I thought), my alternator stopped working. After 4 days of troubleshooting and replacing alternator and it still not working, I discovered that the speedo and the alternator were on the same fuse. Astonishing.
I’m glad you got it fixed but yea some fuses tie into other electroical components. So if one goes out it can make them all fail. Or not work as they should
No. The SRS light is still on. I tried again to get something, anything from the SRS light either with the service connector or the SRS MES connector reset procedure. Nothing. Not even a flicker. I also checked the SRS fuse. It was good. My only guess is that the SRS system unit has a hard code in it that can’t be reset by DIY processes. I ordered a replacement SRS main unit off eBay that is a known-good unit from a ’94 GSR that was never in an accident. I’ve read that others have had success doing this. For $15, it’s worth a try. Thanks for staying with me on this. I appreciate it. Haven’t heard from any others.
Hey NightHawk92. Since you’re the only one who ever replied to me, I thought I would let you know how I made out with the replacement airbag main computer module that I was hoping would clear my SRS light that wouldn’t go off. The replacement module didn’t work. So, I had to dive even deeper into my integra service manual and the integra forums. Here’s what I found. Stepping through some airbag system troubleshooting steps, I had to disconnect the driver’s and passenger’s airbag connectors to the main module. When I took the glove box off to disconnect the passenger’s airbag connector, I found that it was connected to the red short connector. No earthly idea why that was plugged into that instead of its regular connector. So I made the switch, plugged everything back in, reconnected the battery, started the car and BOOM!, the SRS light went out after its 6 second bulb check. Amazing. So, the previous airbag computer module was likely not bad or had a crash code on it as I suspected. So glad to have this resolved. Now, we can take the car for its Virginia safety inspection with no worries or fear of failure. Thanks for your help, sir. Hopefully, this will help someone else too. Happy New Year. 2015 is going to be amazing!
I’m glad you got the issue with the airbag light resolved. And im wondering why the airbag module connector was connected to the airbag dummy plug? But Diagnosing the SRS system can be complicated but you did great on finding what the problem was. In fact i have dealt with my 03 Accords SRS system before but with the AirBag Cable Reel. So figureing out what was wrong was simlar and of course having the factory service manual Made life easier. But have. Happy New Year.
