Nissan Sentra Service Manual: Eco mode control
ECO MODE CONTROL : System Description
SYSTEM DIAGRAM
SYSTEM DESCRIPTION
- ECM receives an ECO mode signal from combination meter via CAN communication and improves the fuel economy by controlling the throttle movement to less than usual. Therefore, driving characteristic is controlled (reducing energy consumption by decreasing needless acceleration and deceleration), so that driving that improved operational fuel efficiency is assisted.
- ECM receives an ECO mode signal from TCM via CAN communication and improves the fuel economy by controlling the throttle movement to less than usual.
- ECM transmits an ECO mode indicator lamp signal to the combination meter via CAN communication.
NOTE:
For the details of the ECO mode, refer to DMS-26, "ECO MODE CONTROL : System Description" (CVT models) or DMS-6, "ECO MODE CONTROL : System Description" (M/T models).
