cuit

sively low line pressureP0746CVT-102

function is detectedP0826CVT-113

ary pressure sensor) is too high or too low while drivingP0840CVT-118

value while drivingP0868CVT-131
TCM-POWER SUPPLY

When the power supply to the TCM is cut OFF, for example
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)P1701CVT-134
TP SEN/CIRC A/TTCM does not receive the proper accelerator pedal position signals
(input by CAN communication) from ECMP1705CVT-139
ESTM VEH SPD SIG

CAN communication with the ABS actuator and the electric unit
(control unit) is malfunctioning

There is a great difference between the vehicle speed signal from
the ABS actuator and the electric unit (control unit), and the vehi-
cle speed sensor signalP1722CVT-141
CVT SPD SEN/FNCTNA rotation sensor error is detected because the gear does not
change in accordance with the position of the stepping motor

DTC U1000 CAN COMMUNICATION LINEPFP:23710
DescriptionBCS001GS
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 LogicBCS001GT
Diagnostic trouble code “U1000 CAN COMM CIRCUIT” with CONSULT-II is detected when TCM cannot com-
municate to other control units.
Possible CauseBCS001GU
Harness or connectors
(CAN communication line is open or shorted.)
DTC Confirmation ProcedureBCS001GV
NOTE:
If “DTC Confirmation Procedure” has been previously performed, always turn ignition switch OFF and
wait at least 10 seconds before performing the next test.
After the repair, touch “ERASE” on “SELF-DIAG RESULTS” and then perform the following procedure to con-
firm the malfunction is eliminated.
WITH CONSULT-II
1. Turn ignition switch ON. (Do not start engine.)
2. Select “DATA MONITOR” mode for “TRANSMISSION” with
CONSULT-II.
3. Start engine and wait for at least 6 seconds.
4. If DTC is detected, go to CVT-55, "
