TROUBLE DIAGNOSIS
DTC Inspection Priority ChartINFOID:0000000005397785
If some DTCs are displayed at the same time, perform inspections one by one based on the following priority
chart.
NOTE:
If DTC “U1000” is displayed with other DTCs, first perform the trouble diagnosis for DTC “U1000”.
Refer to
CVT-56
.
Fail-SafeINFOID:0000000005397786
The TCM has an electrical fail-safe mode. This mode make s it possible to operate even if there is an error in a
main electronic control input/output signal circuit.
FAIL-SAFE FUNCTION
If any malfunction occurs in a sensor or solenoid, this function controls the CVT to make driving possible.
Secondary Speed Sensor
The shift pattern is changed in accordance with thrott le position when an unexpected signal is sent from the
secondary speed sensor to the TCM. T he overdrive-off mode is inhibited, and the transaxle is put in “D”.
Primary Speed Sensor
The shift pattern is changed in accordance with thro ttle position and secondary speed (vehicle speed) when
an unexpected signal is sent from the primary speed sensor to the TCM. The overdrive-off mode is inhibited,
and the transaxle is put in “D”.
Transmission Range Switch
If an unexpected signal is sent from the transmission range switch to the TCM, the transaxle is put in “D”.
CVT Fluid Temperature Sensor
If an unexpected signal is sent from the CVT fluid temperature sensor to the TCM, the gear ratio in use before
receiving the unexpected signal is maintained or t he gear ratio is controlled to keep engine speed under 3500
rpm.
Secondary Pressure Sensor
• If an unexpected signal is sent from the secondary pressure sensor to the TCM, the secondary pressure
feedback control is stopped and the offset value obtai ned before the non-standard condition occurs is used
to control line pressure.
• If secondary pressure sensor error signal is input to TCM, secondary pressure feedback control stops, but line pressure is controlled normally.
Line Pressure Solenoid
If an unexpected signal is sent from the solenoid to the TCM, the line pressure solenoid is turned OFF to
achieve the maximum fluid pressure.
Secondary Pressure Solenoid
If an unexpected signal is sent from the solenoid to t he TCM, the secondary pressure solenoid is turned OFF
to achieve the maximum fluid pressure.
Torque Converter Clutch Solenoid
If an unexpected signal is sent from the solenoid to t he TCM, the torque converter clutch solenoid is turned
OFF to cancel the lock-up.
Step Motor
If an unexpected signal is sent from the step motor to the TCM, the step motor coil phases “A” through “D” are
all turned OFF to hold the gear ratio used right before the non-standard condition occurred.
CVT Lock-up Select Solenoid
If an unexpected signal is sent from the solenoid to the TCM, the CVT lock-up select solenoid is turned OFF to
cancel the lock-up.

U1000 CAN COMM CIRCUIT
U1000 CAN COMM CIRCUIT
DescriptionINFOID:0000000005397799
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 vehi
cle, 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 li ne) allowing a high rate of information transmission
with less wiring. Each control unit transmits/recei ves data but selectively reads required data only.
On Board Diagnosis LogicINFOID:0000000005397800
• This is an OBD-II self-diagnostic item.
• Diagnostic trouble code “U1000” with CONSULT-III is detected when TCM cannot communicate to other
control units.
Possible CauseINFOID:0000000005397801
Harness or connectors
(CAN communication line is open or shorted.)
DTC Confirmation ProcedureINFOID:0000000005397802
NOTE:
If “DTC Confirmation Procedure” has been previously performed, alw ays 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-III
1. Turn ignition switch ON. (Do not start engine.)
2. Select “DATA MONITOR” mode fo r “TRANSMISSION” with CONSULT-III.
3. Start engine and wait for at least 6 seconds.
4. If DTC is detected, go to CVT-58, "
Diagnosis Procedure" .
WITH GST
Follow the procedure “WITH CONSULT-III”.
