Oh great. Now I have to spend the rest of my day with J. Geils running through my brain.

Can't you pull the battery and clear the freeze frame data?

I am now sorry I started that!

So in regards to freeze frame.

The tech was talking about this failure and it actually happening on corollas a lot and i actually mentioned to him he could look at my computer and see it never went outside of factory limits because i know how to drive and he flat stated that the computer doesnt save that info as "this isnt GM". The only reason they got this freeze frame data is due to the code P0303 being thrown and this freeze frame snapshot was saved. Which as i stated, that code didnt accompany this failure as i never had a misfire.

Let me help with that...

1. The system records a multitude of vehicle operating parameters every half second.

2. When a qualifying fault is detected, a snapshot is saved. The snapshot includes 2 or 3 preceding (I don't remember exactly) freeze frames, another at the time of the fault, and one more immediately after. The snapshot is read/downloaded by techstream.


I don't think this is the EDR. I have no idea how that works. :/

Yup, my standard universal OBD2 reader pulled the snapshot data the few times I've had the coilpack failure code, never bothered to look at the others, but I remember looking at the one that happened heading up to turn 5 at Laguna Seca, >6k rpm, ~80-something mph, that's when I decided I wasn't going to waste much time attempting a warranty repair on 'em...

I can't recall if my bluetooth dongle could do it too, I know the scanner I have is relatively higher end, compatible with Toyota/GM protocols so that may be why it was able to pull it.

But as above, not really relevant to the rocker arm failure that should be front and center.

Yes, agreed. So far, as stated by the service rep, the implied digital evidence is exculpatory.

The car never had a noticeable misfire that would throw a P0303 code when this failure occurred. I was driving, saw smoke from the front passenger side, thought it was the bucket of a dodge next to me, drove to the next light about 2 miles away with full power, no knocks or ticks and no problems, was by myself and noticed the smoke again. Drove another half mile and pulled over, left the car running and got out and examined. Determined smoke coming from under the hood, popped the hood and saw oil and immediately then shut it off... i wouldve known if there was a misfire lol.

Do you, or anyone else know if these snapshots can be seen with ECUTEK hardware?

Even if there was a misfire too small to notice (it can happen) that does not negate the fact that you did not exceed the maximum revs. To deny for an over rev at 7300 is ludicrous.

i think a p0303 is a hard misfire though.

but exactly, its under the factory rev limiter so they need to stop playing.
