Awesome Site! My toyota's CC, when activated will coast about 10-15 miles lower than set point, then down shifts and won't maintain. I seem to be getting enough vacuum and I know the unit knows its on and should be doing something. Any input would be appreciated.
Thanks...

Hi there,

This may be a speed sensor fault, i would try a scan first to see if there are any unresolved fault codes, do this and let me know, i will also look up the system and have a read and see if there are any other tests we can do.
