Code (unreadable) and 3rd brake light failure
OK, I'm driving my '94 Bonneville and the SES light comes on and then, when I put on the brakes, it chimes and shows the 3rd brake light has failed... Then it runs rough and idles poorly. I took it to O'Reilly and they can't get their code reader to even read anything, much less pull a code. I disconnect the battery for a few seconds and restart the car and the SES light is off, the 3rd brake light failure is cleared, and the car runs just fine. This has happened more than once--same symptoms, same results from disconnecting the battery. It'* not a closed-loop/open-loop issue as the car runs fine warmed up or cold (i.e., in open loop and closed loop mode) for a long time before throwing the code and chiming the chime. I know I've got to find somebody (not the dealer! $100+ minimum to hook it up) to pull the code when it shows up, but I'm hoping this combination of events will chime in someone'* memory and they'll say "Oh yeah, I had that happen and it was the -----." Anybody?
