Fail-safe

INFOID:0000000010113945

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 FUNCTION 

If any malfunction occurs in a sensor or solenoid valve, this function controls the CVT to make driving possi-

ble.

Secondary Speed Sensor

The shift pattern is changed in accordance with the throttle position when an unexpected signal is sent from

the secondary speed sensor to the TCM. The manual mode and “DS” mode are inhibited, and the transaxle is

put in “D”.

Primary Speed Sensor

The shift pattern is changed in accordance with the throttle position and secondary speed (vehicle speed)

when an unexpected signal is sent from the primary speed sensor to the TCM. The manual mode and “DS”

mode are 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”.
