Let me just say that any money that you paid, or if you have a subscription, that money stays in your account until the answers are rated, (positive) regardless of how fast or how long it may take to get finished. You can FOLLOW UP AT ANYTIME, even after rating.

Terminal "H" on the CCM is for the cruise control signal 'disengage'. Please see attached diagram, thanks.

It seems that you may need the diagnostics for the cruise control.
