disengage the Cruise Control System.
The BPP sensor is mounted on the brake pedal bracket. Pressing the brake pedal while the cruise control is engaged will disengage the Cruise Control
System. The BCM monitors the BPP sensor via the BPP sensor signal circuit. The BCM sends a GMLAN serial data message to the ECM indicating
the position of the brake pedal. For further information on the BPP sensor, refer to Exterior Lighting Systems Description and Operation and to Brake
Pedal Position Sensor Calibration.
The CPP sensor is mounted on the clutch pedal bracket. Pressing the clutch pedal while the cruise control is engaged will disengage the Cruise Control
System. The ECM monitors the CPP sensor via the CPP sensor signal circuit as the voltage signal decreases while the pedal reaches the fully applied
position.
The Cruise Control System will disengage when the cruise control on/off switch is switched OFF.
The Cruise Control System will disengage when the ECM detects that a driver override function has been active for approximately 60 seconds.
When the Cruise Control System has been disengaged, the ECM sends a GMLAN serial message to the instrument panel cluster (IPC) in order to turn
OFF the Cruise indicator.
The vehicle speed stored in the memory of the ECM will be erased when the cruise control on/off button is turned OFF, or the ignition switch is turned
OFF.
