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. The Cruise Control System will disengage when the cruise control on/off switch is turned OFF.
When the Cruise Control System is disengaged, the ECM sends a class 2 message to the instrument panel cluster (IPC) in order to deactivate the Cruise
indicator. 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.

The Cruise Control System will disengage when the ECM detects that the accelerator pedal override is active for greater than 60 seconds.
