PostSubject: CASE Learn Required When Changing Your PCM?   Fri Dec 19, 2008 7:36 pm

I am going to be getting an INTENSE PCM and wanted to know if getting the CASE LEARN done at the dealer necessary, or can I run the car without doing this?

The car will run without performing the CASE learn although it is highly recommended.
You do not necessarily have to have it performed at the dealership either.
Any good independent mechanic will have the proper alternative scan tool to a Tech 2 such as a Snap-On MT2500 (and others). The crankshaft relearn is necessary after replacing a crankshaft sensor as well. So any decent shop can perform this test. I was quoted $20.00 at a shop down the street from me, I was told it only takes 5 Mins to do.

My PowrTuner software says the car will trigger SES and throw a code if it needs a CASE learn. I've reprogrammed my PCM (not replaced) over 60 times and never did a CASE learn.

Then I guess it's just recommended but not necessary.

Note:
I just read a little more and if there is a problem it will throw a code "P1336".
So the answer to EASHER's question should be "only necessary if you get an SES and code.

depends on what year your riv is also. Mines a 96 all I had to do was swap out the knock modulater and I was done. I think for a 98 it is highly recommended or the car wount run right.

From what I understand it should be done after any PCM change. You may not get a code, but they may not be quite in sync either. You won't throw the code unless they are way out of sync.
