Thanks Sugiami. I appreciate that the CC operates through the break pedal limit switch and that is why I removed it and shorted it out so that the CC would think that the break was not pushed and therefore CC should operate. Shorting out the limit switch did not cause the CC to operate. Do you think that it is worth fitting a new limit switch anyway? Could the engine management computer sence that the contact from the break switch is not working when the ignition is first switched on and the break pedal is depressed to disengage the engine from park to drive - at this point there would be a change of state for the CC signal also and if not detected could this cause the CC to be disabled? Only a thought - what do you experts think. Thanks.
