When the brake is on, battery positive voltage is normally applied through the STOP fuse and the stop light switch to terminal STP of the ECM, and the ECM turns the cruise control OFF. If the harness connected to terminal STP has an open circuit, terminal STP will have battery positive voltage and the cruise control will be turned OFF.
