Circuit/System Verification

IMPORTANT: The cruise on/off switch must be ON in order to view all of the cruise control parameters properly.

Ignition ON, observe the scan tool Cruise Control Switch parameter in the BCM while pressing the various cruise control switches. The reading should be Error.

If the Cruise Control Switch parameter toggles between On, Off, Resume, Set and Cancel accordingly with the depressed switches, then replace the ECM.
