3C-21 Transfer: Motor-Shift Type (Transfer with Shift Actuator)
NOTE
“O” in transfer position indicator column of the above table means indicator lights up when DTC is
detected.
Fail-Safe Table
S5JB0E3314008
This function is provided by the safe mechanism that assures safe drive ability even when the actuator, switch, sensor
or its circuit fails. The following table shows the fail safe function for each fail condition of sensor, actuator, switch,
4WD control module or its circuit.
