the brake pedal while the cruise control is engaged will disengaged the Cruise Control System. The ECM monitors the TCC brake switch/cruise control
release signal circuit and the stop lamp switch signal circuit. When the brake pedal is pressed, the normally closed TCC brake switch opens and the
normally open stop lamp switch closes. The ECM detects a low signal voltage on the TCC brake switch/cruise control release signal circuit and detects a
high signal voltage on the stop lamp switch signal circuit, and disengages the cruise control system.
The Cruise Control System will disengage when the ECM detects that the accelerator pedal override is active for greater than 60 seconds.
The Cruise Control System will disengage when the cruise control on/off switch is turned OFF. The vehicle speed stored in the memory of the ECM will
be erased when the cruise control on/off switch is turned to OFF, or the ignition switch is turned OFF.
When the Cruise Control System is disengaged, the ECM sends a serial data message to the instrument panel cluster (IPC) in order to deactivate the
cruise engaged indicator.
