When the PCM detects that code it will shut the cruise control down. That code is the solenoids in the cruise servo. They are fed voltage and grounded thru the PCM when comanded to. Its much easier to test and check with the wireing book but you can make sure you have voltage to the servo and then check the ohms and continuity of the three solenoids in the servo. It may be the servo or the wireing or PCM. I dont remember the ohms but check all three and I believe they are all the same. Course there is much more to make the cruise not work but with that code it sounds like one of the solenoids or wireing and lastly it could even be the PCM. Ron
