Cruise Control Module: Description and Operation
AUTO-CRUISE CONTROL-ECUThe auto-cruise control-ECU consists of the input interface circuit, microprocessor, constant voltage power supply circuit, microprocessor monitor circuit and output interface circuit. Signals from the vehicle speed sensor, TPS and each switch are input into the auto-cruise control-ECU.
It processes them according tb the program in the microprocessor memory and outputs control signals to the actuator. It also outputs system self-diagnosis results and conditions of input signals to the diagnostic output terminal.
