I am trying to figure out of the TCC is actually engaging or not. The scanner has 3 TCC applied channels. One of the three changes from "No" to "Yes" at the appropriate times TCC should be engaged. However, the other two channels do not. From the feel and RPM, I don't think TCC is engaging.

So, what channel do I need to verify if the TCC is engaged? Is there a way to force it to engage using editor? I already looked at the misfire channels and after driving for 20 minutes, had 2 misfires on number 3 and 7. This doesn't seem like enough misfires to stop the TCC. Open to any advice.

Thank!
