Fail-safe INFOID:0000000004235511

The TCM has an electrical fail-safe mode. In this mode TCM operates even if there is an error in a main elec-tronic control input/output signal circuit.

FAIL-SAFE FUNCTIONIf any malfunction occurs in a sensor or solenoid valve, this function controls the CVT to make driving possi-ble.



Secondary Speed SensorThe shift pattern is changed in accordance with throttle position when an unexpected signal is sent from thesecondary speed sensor to the TCM. The manual mode and overdrive control mode are inhibited, and thetransaxle is put in “D”.Primary Speed SensorThe shift pattern is changed in accordance with throttle position and secondary speed (vehicle speed) whenan unexpected signal is sent from the primary speed sensor to the TCM. The manual mode and overdrive con-trol mode are inhibited, and the transaxle is put in “D”.Transmission range SwitchIf an unexpected signal is sent from the transmission range switch to the TCM, the transaxle is put in “D”.Manual Mode SwitchIf an unexpected signal is sent from the manual mode switch to the TCM, the transaxle is put in “D”.CVT Fluid Temperature SensorIf an unexpected signal is sent from the CVT fluid temperature sensor to the TCM, the gear ratio in use beforereceiving the unexpected signal is maintained or the gear ratio is controlled to keep engine speed under 5,000rpm.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 obtained before the non-standard condition occurs is usedto control line pressure.

• If secondary pressure sensor error signal is input to TCM, secondary pressure feedback control stops, butline pressure is controlled normally.

Line Pressure Solenoid ValveIf an unexpected signal is sent from the solenoid valve to the TCM, the line pressure solenoid valve is turnedOFF to achieve the maximum fluid pressure.Secondary Pressure Solenoid ValveIf an unexpected signal is sent from the solenoid valve to the TCM, the secondary pressure solenoid valve isturned OFF to achieve the maximum fluid pressure.Torque Converter Clutch Solenoid ValveIf an unexpected signal is sent from the solenoid valve to the TCM, the torque converter clutch solenoid valveis turned OFF to cancel the lock-up.Step MotorIf an unexpected signal is sent from the step motor to the TCM, the step motor coil phases “A” through “D” areall turned OFF to hold the gear ratio used just before the non-standard condition occurred.Lock-up Select Solenoid ValveIf an unexpected signal is sent from the solenoid valve to the TCM, the lock-up select solenoid valve is turnedOFF to cancel the lock-up.TCM Power Supply (Memory Back-up)Transaxle assembly is protected by limiting the engine torque when the memory back-up power supply (forcontrolling) from the battery is not supplied to TCM. Normal status is restored when turning the ignition switchOFF to ON after the normal power supply.

DTC Inspection Priority Chart INFOID:0000000004235512

If some DTCs are displayed at the same time, perform inspections one by one based on the following prioritychart.NOTE:If DTC “U1000”/“U1010” is indicated with other DTCs, start from a diagnosis for DTC “U1000”/“U1010”.Refer to TM-48, TM-49.
