TCM-POWER
SUPPLY

When the power supply to the TCM is cut OFF, for exam-
ple because the battery is removed, and the self-diagnosis
memory function stops

This is not a malfunction message (Whenever shutting
OFF a power supply to the TCM, this message appears on
the screen)P1701 —CVT-145

signals (input by CAN communication) from ECMP1705 —CVT-150
ESTM VEH SPD
SIG*2

CAN communication with the ABS actuator and the elec-
tric unit (control unit) is malfunctioning

There is a great difference between the vehicle speed sig-
nal from the ABS actuator and the electric unit (control
unit), and the vehicle speed sensor signalP1722 —CVT-152

not change in accordance with the position of the stepping
motor
