INPUT/OUTPUT SIGNAL CHART 

BCM CONTROL 

• BCM receives the ECO mode switch signal (ON/OFF) by hard wire. BCM transmits ECO mode signal to other control unit via CAN communication.
• BCM transmits ECO mode indicator signal to combination meter via CAN communication. Combination meter illuminates ECO mode indicator according to the signal
• For Air Conditioning Control details. Refer to System Description (Auto A/C) or System Description (Manual A/C).

NOTE:

• When the ignition switch is placed ON while the ECO mode indicator stays ON, the ECO mode indicator automatically turns ON at the next ignition switch ON.
• The ECO mode system cannot be turned off while the accelerator pedal is depressed even if the ECO mode switch is pushed to OFF. (ECO mode indicator turns OFF.) Release the accelerator pedal to turn off the ECO mode system.

ECM CONTROL 

ECM receives the ECO mode signal from BCM via CAN communication and improves the fuel economy by controlling the throttle movement to less than usual.

TCM CONTROL 

TCM receives the ECO mode signal from BCM via CAN communication and improves the fuel economy by controlling the driving characteristic (for decreasing needless acceleration and deceleration, reducing energy consumption, and fixing to ECO gear shift schedule), so that operation of fuel efficiency driving is assisted.
