I have spent the last 3 months trouble shooting the speed control and everything I test is ok except the dump valve is always open. Question I was reading on automatic test process when the ignition is turned on all active functions light and after the test passes the light turns off. In my reading when the ignition is turned on I do not see the "Cruse" light in the VFD. Would this indicate cruse control is disabled in ECM/PCM?


Thank you

If the "cruise" light does not turn on when the on/off button is pressed, then your ECM needs to have the cruise control reset via a dealer scan tool (DRB). I am not sure what you are referring to with the "dump valve" reference?

If you ship your ECM to us for a tune, we can also reset the cruise for you as a side benefit. Good luck.
