INPUT/OUTPUT SIGNAL CHART
| Signal name | Input | Output | Description |
|---|---|---|---|
| ECO mode signal |
|
BCM | Transmits ECO mode signal to ECM, TCM and A/C auto amp meter via CAN communication. |
| ECO mode indicator signal | Combination meter (CAN) | BCM | Transmits ECO mode indicator signal to combination meter via CAN communication. |
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).
- 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.
A/C AUTO AMP. CONTROL
For details of air conditioning control, Refer to System Description .
A/C AMP. CONTROL

FAIL-SAFE
If a malfunction occurs in the system of CVT during ECO mode, the ECO mode is kept until ignition off, ECO mode is turned off automatically at the next ignition switch ON.
