through body grounds M16, M50 and M70 (Diesel engine models).
WATER TEMPERATURE GAUGE
The water temperature gauge indicates the engine coolant temperature.
ECM provides a water temperature signal to combination meter for water temperature gauge with CAN com-
munication line.
TACHOMETER
The tachometer indicates engine speed in revolution per minutes (rpm). ECM provides an engine speed signal
to combination meter for tachometer with CAN communication line.
FUEL GAUGE
The fuel gauge indicates the approximate fuel level in the fuel tank.
The fuel gauge is regulated by a variable resistor signal supplied
●
to combination meter terminal 47 for the fuel level sensor
●
from terminal 4 of the fuel level sensor unit
●
through terminal 1 of the fuel level sensor unit and
●
through combination meter terminal 46
SPEEDOMETER
ESP/TCS/ABS control unit or ABS actuator and electric unit (control unit) provides a vehicle speed signal to
the combination meter for the speedometer with CAN communication line.

CAN Communication
EKS009A3
SYSTEM DESCRIPTION
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.
