Mat got me the PCM tune, and we installed it today. He did the security relearn and everything went okay. Now we haven't done the case relearn yet, but we noticed that our SES light is not on when it is supposed to be on due to the lack of the case relearn. Why would this be?
It says on the paper that we got from PCMforless...
The check engine light is disabled on the loaner PCM so that it will not illuminate.
But we did not get a loaner, we got the core, so the light shouldn't have been disabled. If the light was not disabled, we should have the SES light on, but we don't. Why would this be? And should we still get the case relearn done?
Hope this makes sense?
