Adaptive speed control module - vehicles with adaptive speed control
System operation The speed control system is inoperative below 43 kph (27 mile/h) and inoperative above the following speeds: 193 kph (120 mile/h) for vehicles fitted with a 3.0L engine. 201 kph (125 mile/h) for all other variants. The speed control system is designed to maintain a selected vehicle speed between these two parameters.
Any of the switches operated by the brake will interrupt the speed control operation by switching the signal to the engine control module (ECM). This will allow the system to go into STANDBY mode. Pressing the RESUME switch with the vehicle travelling above 43 kph (27 mile/h) while the system is in STANDBY mode will allow the vehicle to accelerate until the last set speed is resumed. Steering Wheel Switches RESUME Switch When the RESUME switch is pressed with the vehicle travelling above 43 kph (27 mile/h) with the system in STANDBY mode, the vehicle is allowed to accelerate until the last set speed is resumed. The RESUME switch will not function if the ignition switch has been cycled or if the vehicle speed is below 43 kph (27 mile/h). CANCEL Switch When the CANCEL switch is pressed with the vehicle travelling above 43 kph (27 mile/h) the system will enter STANDBY mode. SET Switch When the SET +/- switch is pressed with the vehicle travelling above 43 kph (27 mile/h) the system allows the vehicle speed to be maintained to ± 1.62 kph (1 mile/h). Pressing the SET +/- switch will increase or decrease the vehicle speed respectively until the switch is released. If the respective switch is pressed momentarily, the speed will accelerate or decelerate in 1.62 kph (1 mile/h) increments. Brake Pedal Position (BPP) Switch If the brake pedal is activated while the speed control system is active, the ECM receives a signal from the brake pedal position switch. This will cancel speed control and allow the throttle blade to return to the position as demanded by the accelerator pedal. |
