TROUBLE DIAGNOSIS
TROUBLE DIAGNOSIS
DTC Inspection Priority ChartINFOID:0000000005928748
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:0000000005928749
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.
