89 CRX DX auto. runs fine but every 30 seconds to every few minutes I will get the "ding ding ding ding" that sounds like my door is open, but the door ajar light does not light (it normally will). Also, get a CEL randomly , try to check the error code but it just short blinks constantly (i stopped counting after 41 blinks)

Seems to happen during deceleration, or during braking , sometimes on hard turns.


Reset ECU but the problem came back (as I would suspect with a short)

What are the best methods for tracking down a short ???

 

Idk about the short, but your ecu is flashing code 1- O2 sensor.

Thanks !!! Exhaust is leaking could a decent sized exhaust leak cause the 02 sensor to trip the CEL ??

 

if its before the sensor possibly. but i dont think its related. it could be a bad door switch doors your dome light come on when its dings? thatd be the switch if it does, or swap the pass. or rear switch if you got a 4dr

 

The seat buckle has a plug under the seat see if that's plugged in mine did that with it unplugged

 

The beeping your hearing is your door pins being partially pushed in and not pushed in. Chances are they are rusty, possibly bent or stuck together so they are always shorting, and saying that the door is open. I tried cleaning mine so that my alarm would work better, and go off when the doors opened but it would just always go off for no reason lol. imo try that, take out the door pins (little black L shaped pieces in the door jam) and see if it makes the noise.

 

Hey, a DX Auto. You're honestly one of the only people that I've ever heard of owning one besides myself.
