System Description The current flows from the GAUGE fuse to terminal 3 and terminal 12 of the CCS computer. When the ignition switch is on, the current flows from the battery to Terminal 2 of the main relay. 1. MAIN SWITCH OPERATION When the CCS switch is turned on (pushed in), the current flows from Terminal 2 → Terminal 4 of the CCS main relay — main switch — body ground. And then, turn on (closes) the relay contacts in the main relay. As a result, current flows from terminal 2 → terminal 6 of the main relay — So it is supplied to terminal 10 of the CCS computer. Therefore, the main relay remains on and continues to supply current to the CCS computer. 2. CONTROL SWITCH OPERATION When the control switch is set each position → sends a signal to terminal *4 or **1 of control switch → terminal 17 of CCS computer. 3. SPEED CONTROL OPERATION When the vehicle speed is set by the control switch, the CCS computer sends a signal to terminal 2 of CCS computer → terminal 2 → terminal 4 of stop light switch → terminal 1 of actuator (release valve side). At the same time, the CCS computer sends a signal from terminal 4 of the CCS computer to terminal 2 of actuator (control valve side). Then, the actuator increases or decreases the throttle valve opening angle in accordance with the signal from the CCS computer. 4. CANCEL SWITCH OPERATION The CCS is provided with several types of cancel switch, such as the Cancel switch of Control switch, the Stop Light switch, the Parking Brake switch, and the Neutral Start switch (A/T model) or Clutch switch (M/T model). (a) Cancel Switch of Control Switch When the Cancel switch is pushed on → Sends a cancellation signal to Terminal *4 or **1 of control switch → Terminal 17 of CCS computer. (b) Parking Brake Switch When the parking brake lever is pulled, the Parking Brake switch turned on → Sends a cancellation signal (earth voltage) to Terminal 12 of the CCS computer. (c) Neutral Start Switch (A/T models) When the shift lever is set to the P or N range, the Neutral Start switch goes on → Sending a cancellation signal (earth voltage) to Terminal 11 of CCS computer. (d) Clutch Switch (M/T model) When the clutch pedal is depressed on, the Clutch Switch goes on → Sending a cancellation signal (earth voltage) to Terminal 11 of CCS computer. (e) Stop Light Switch When the brake pedal is depressed, switch A of the stop light switch is turned off → the release valve of actuator is opened. At the same time, switch B of the stop light switch is turned on → the current flows through terminal 1 → terminal 3 of the stop light switch → stop light → body ground → the battery voltage is applied to terminal 15 of CCS computer via this switch. Thereby, the actuator is shut off. Therefore, the operation of CCS is canceled and the actuator is shut off due to the operation of these switches. *: U.S.A (w/ Airbag system) **: CANADA (w/o Airbag system)
