CAN COMMUNICATIONPFP:23710
System DescriptionEFS0055T
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.

In a case that temperature detected by ambient sensor is lower than indicated temperature before turning
ignition switch off.
–Temperature detected by ambient sensor is indicated when turning ignition switch ON.
Indication During Running
Though temperature detected by ambient sensor temporarily changed, indicating temperature continentally
indicates.

In a case that temperature detected by ambient sensor is higher than indicated temperature.
–If vehicle speed is more than 20 km/h(13 MPH), elevation of indicating temperature is limited according to
the speed until temperature detected by ambient sensor is indicated.
NOTE:
Vehicle speed 20 km/h (13 MPH): 256 sec., 25 km/h (16 MPH): 238 sec., 35 km/h (22 MPH): 200 sec., 50
km/h (31 MPH): 144 sec., 65 km/h (40 MPH): 88 sec., more than 80 km/h (50 MPH): 32 sec.
–If vehicle speed is more than 20 km/h (13 MPH), and that temperature detected by ambient sensor
becomes 8 °C (46 °F) more than indicating temperature, indicating temperature will be elevated unit the
degree becomes same as temperature detected by ambient sensor with limiting elevation of indicating
temperature 1 °C par a minute.
–If vehicle speed is less than 20 km/h (13 MPH), indicating temperature is continually kept.

In a case that temperature detected by ambient sensor is lower than indicated temperature.
–Temperature detected by ambient sensor is indicated during running.
