TURBINE REVOLUTION SENSOR
DescriptionINFOID:0000000001713049
The turbine revolution sensor (power train revolution sensor) detects forward clutch drum rpm (revolutions per
minute). It is located on the input side of the automatic transaxle. The vehicle speed sensor A/T (Revolution
sensor) is located on the output side of the automatic transaxle. With the two sensors, input and output rpms
are accurately detected. As a result, optimal shift timing during deceleration and shift quality can be improved.

CAN COMMUNICATION LINE
DescriptionINFOID:0000000001713064
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 malfunction detection ability.
Many electronic 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 con-
nected 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.
On Board Diagnosis LogicINFOID:0000000001713065
Diagnostic trouble code “U1000 CAN COMM CIRCUIT” with CONSULT-III or 12th judgement flicker without
CONSULT-III is detected when TCM cannot communicate to other control units.
