ENGINE MANAGEMENT SYSTEM – TD 18-1-42 DESCRIPTION AND OPERATION Description General The cruise control system is integrated with the engine management system and uses fuelling intervention to automatically maintain a set vehicle speed. Once engaged, the system can also be used to accelerate the vehicle without using the accelerator pedal. The cruise control system comprises the following components: l On/Off/Suspend switch land' (set/accelerate and decelerate) steering wheel switches l Resume switch l Rotary coupler l Cruise control warning lamp. The cruise control system also uses inputs from the brake pedal switch, the APP sensor, the ECM and the ABS ECU. The cruise control is operated by the driver using only the steering wheel switches. When cruise is active, the ECM regulates the PWM signals to the fuel injectors to adjust the fuel supply as required to maintain the set speed.
