The Custom Cruise III system contains a built in delay feature when it is first turned on. Specifically, with this system, only after the multifunction lever switch has been in the "on" position for approximately one to two seconds will the cruise control system engage -- with depression of the set/coast button. The reason for this time delay is two fold:
^ It allows ample opportunity for the electronic control module (cruise controller) to correctly interpret vehicle speed.
^ Secondly, an important safety consideration is yielded as well. This same delay prevents the cruise controller from storing an uncalled-for "set" speed.
This built in delay could be mis-diagnosed as a malfunctioning cruise control system.
