CRUISE CONTROL SYSTEM This system is controlled by the ECM, and is activated by the throttle position sensor and motor. The ECM controls the following functions: ON-OFF, SET / COAST, RESUME / ACCEL, CANCEL, vehicle speed operation, motor output control, and shift down control. The ECM compares the driving vehicle speed from the vehicle speed sensor with the stored vehicle stored speed. The ECM receives signals such as ON-OFF, SET / COAST, RESUME / ACCEL, and CANCEL from the cruise control main switch and executes them. The ECM illuminates the combination meter's cruise control indicator light when it receives the cruise control main switch ON signal. The ECM illuminates the combination meter assembly cruise control SET indicator light when vehicle speed control begins after the cruise control switch is pushed to -SET while driving. The ECM cancels the cruise control system when the brake pedal is depressed and the ECM receives the stop light switch signal. The ECM cancels the cruise control system when the shift lever is moved from D (6th, 5th, 4th, 3rd, 2nd or 1st gear) to N or when the shift lever is used to select the 3rd, 2nd or 1st gear with the shift lever in S, and the ECM receives the PNP switch signal. cruise control switch 2. LIMIT CONTROL (a) Low speed limit control operation will be automatically canceled and the stored vehicle speed will be maintained when the vehicle speed decreases below the low speed limit 40 km/h (25 mph) while the cruise control is in operation. (b) High speed limit RESUME / ACCEL cannot be used to increase speed beyond the high speed limit. 3. OPERATION OF CRUISE CONTROL The cruise control main switch operates 7 functions: SET, COAST, TAP-DOWN, RESUME, ACCEL, TAP-UP, and CANCEL. The SET, TAP-DOWN and COAST functions, and the RESUME, TAP-UP and ACCEL functions are operated with the same switch. The cruise control main switch is an automatic return type switch which turns on only while operating it in each arrow direction and turns off after releasing it. (a) SET CONTROL Vehicle speed is stored and constant speed control is maintained when pushing the switch to SET / COAST while driving with the cruise control main switch ON (the cruise control indicator light is on), and the vehicle speed is within the set speed range (between the low and high speed limits).
