Hey Everyone. So my dash has gone Crazy The ABS, E-Brake, Trac Off and the "Service Traction Soon" Light is on in the Info center, But that is the only messages that goes away after about 3 minutes of driving. My check engine light is on from when I replaced my catalytic converter. I replaced both O2 sensors and it still won't go away :\ Anyone have any info on my ABS issues?

 

CEL light because of Cat is probably because the replacement isn't the exact same spec as OEM. These cars are very picky, and you won't get that CEL to shut-off without tuning the P0420 code out of the PCM.

Check your Brake Fluid Level, that can affect the BRAKE light. A wheel hub assembly/sensor can trip the other lights.

If all of those things check out, you might be getting some electrical gremlin that is harder to track down.

 

There may be one alternative to stopping the P0420. Look up a trick using a "Spark Plug Non-Fouler". Basically, you space the rear O2 sensor out of the exhaust stream. I read a LOT of people claim success with that trick on all kinds of makes/models. If all you were doing was getting a tune to rid that code, I'd explore that trick first.
